The town's doorstep canyon, bottom to top

Ephraim Canyon, the road up to Skyline Drive.

Ephraim Canyon is the road that climbs east out of town into the Wasatch Plateau. It leaves US 89 at the south end of Ephraim, gains close to a mile of elevation past Lake Hill Reservoir and the old Great Basin research station, and tops out on Skyline Drive along the roof of the plateau. This page stays with Ephraim's own canyon: the drive, the reservoir, the history and the seasons. The plateau road itself, Skyline Drive, is its own Central Utah page, named and linked where it comes up.

The short answer

Ephraim Canyon is the town's doorstep road east into the Wasatch Plateau. It leaves US 89 at the south end of Ephraim, climbs close to a mile in elevation, passes Lake Hill Reservoir about five miles up and the historic Great Basin research station, and meets Skyline Drive near 10,000 feet on the plateau. The lower canyon is paved and open through much of the year; the top holds snow into July and closes again with the first heavy storms in late fall. From the top the road carries on over the plateau toward Orangeville and the Emery County side.

The canyon road and the climb

East off US 89 Free Paved low, dirt high

Ephraim Canyon Road turns east off US 89 near the south end of town and heads straight for the mountain wall behind Ephraim. Within a few minutes the valley farmland is behind you and the road is climbing through scrub oak and then into pine and aspen. From the valley floor at about 5,500 feet it gains close to a mile of elevation before it reaches the top of the plateau.

The lower canyon is paved, and any car can manage the first stretch to Lake Hill Reservoir in dry weather. Higher up the pavement gives way to a graded dirt Forest Service road that gets rougher and slower as it climbs, so a higher clearance vehicle earns its keep near the top. There is no fuel, no store and thin cell signal once you leave town, so top off the tank and download a map first.

Keep going and the road does not dead end at the ridge. It meets Skyline Drive along the spine of the plateau and then carries on over the top and down the far side toward Orangeville, in Emery County, a long unpaved mountain crossing that is only open in the snow free months. Most Ephraim trips turn around at the reservoir, the station or the Skyline junction rather than driving the whole way across.

Getting there

From Main Street in Ephraim, drive to the south end of town and turn east off US 89 onto the canyon road; it starts climbing right away. In town it doubles as a bike route for the first mile before the grade steepens and the traffic thins to a handful of trucks and trailers.

Before you go

  • The first paved miles suit any car in dry weather; the dirt near the top wants higher clearance and dry conditions.
  • There is no fuel or service up the canyon, so fill up and pack water before you leave Ephraim.
  • Cell signal fades as you climb, so download your map in town.
  • In spring and after storms the dirt turns to mud up high, and snow lingers at the top into July.

Lake Hill Reservoir and Campground

About 5 miles up 8,400 feet Roughly May to September

Lake Hill Reservoir is the canyon's water, a small man made lake about five miles up at roughly 8,400 feet, ringed by spruce, fir and aspen. It is calm and scenic rather than large, the kind of place people bring a canoe or a float tube on a summer morning. The Utah Division of Wildlife Resources stocks it with rainbow and tiger trout, so it fishes well from the bank or a small boat, and it is shallow and quiet enough to be an easy stop with children.

Lake Hill Campground sits right beside the water, a Forest Service campground with a mix of single and group sites, vault toilets and drinking water, shaded by the mixed forest. It runs a summer season, opening around May and closing in September once the nights turn cold. Because it is up at 8,400 feet, it stays cool through the summer when the valley below is hot, which is much of the point of camping up here.

For a lot of people in Ephraim the reservoir is the default canyon outing: fifteen minutes from town, cool air, a little fishing and a picnic, with no need to drive the rough road higher up. It is the one stop on this page that a low car can reach on pavement in summer.

The details

CostFree day use; a fee to camp; a Utah license to fish

Getting there

Drive up Ephraim Canyon Road about five miles; the reservoir and its campground are signed off the road. The pavement generally reaches this far, so a regular car is fine in dry summer weather, and this is where most low clearance cars turn around.

Before you go

  • The state stocks the reservoir with rainbow and tiger trout, and anyone old enough needs a Utah fishing license.
  • Camp sites can be reserved on Recreation.gov in the busy months, so check ahead on a summer weekend.
  • At 8,400 feet the nights are cold even in July, so pack layers.
  • This is the turnaround for most low clearance cars; the road gets rough above the lake.

The Great Basin Station

Up the canyon Run by Snow College A century of research

The most surprising thing up Ephraim Canyon is not a view, it is a research station. Around the turn of the last century the Wasatch Plateau above Ephraim had been grazed nearly bare; by 1900 an estimated half a million sheep summered on the mountain, and the stripped slopes sent summer floods and mud roaring down onto the farms in the valley. In response the federal government set up an experiment station up the canyon in 1912 to find out what was causing the floods and how to stop them.

That station, first called the Utah Experiment Station and later the Great Basin Experimental Range, is regarded as one of the places where the science of range management in this country began. Researchers spent roughly sixty years here studying how grazing, plants and water move on a mountain watershed, and the work helped bring the floods under control. The oldest buildings date to the 1910s, with more added by Civilian Conservation Corps crews in the 1930s, and the cluster is now a listed historic district.

When the on site research wound down the buildings sat mostly empty for years, until Snow College took over the site in 1992 in partnership with the Forest Service and the city. Today it runs as the Great Basin Environmental Education Center, with a museum, an amphitheater and lodging used for college courses, field programs, conferences and retreats. It is the clearest link between Snow College and the mountain at its back.

Getting there

The station sits up Ephraim Canyon on the plateau front, reached by the canyon road. It hosts scheduled programs and group stays rather than casual daily tours, so arrange a visit through Snow College's Great Basin Station office. The Snow College page covers the college side of the story.

Before you go

  • The center runs on a program and reservation basis, not as a walk in attraction, so contact Snow College to visit or stay.
  • The buildings are a listed historic district, so treat the grounds gently.
  • It is the reason Snow College keeps a research and field presence on the mountain, covered further on the Snow College page.
  • Pair a visit with the reservoir below it or a fall color drive higher up.

Skyline Drive at the top

Top of the canyon Near 10,000 feet Mid July into fall

At the head of the canyon the road climbs out of the trees and meets Skyline Drive, the high road that runs the length of the Wasatch Plateau near and above 10,000 feet. This is the payoff at the top of Ephraim Canyon: big open country, wildflowers in high summer, and long views back down over the Sanpete Valley on one side and toward the Emery County canyons on the other.

Skyline Drive itself is a Central Utah subject rather than an Ephraim one, because it belongs to many towns; every canyon from Fairview to Manti climbs up to it. Ephraim Canyon is simply one of the main ways onto it. The plateau road, its length, its high points near 10,900 feet, its OHV network and its season are covered in full on the region Skyline Drive page rather than repeated here.

What matters from Ephraim's side is the timing. The top does not melt out until about mid July, late September storms can turn the dirt to a bog, and the first heavy snows close it again for the winter. So the window for driving all the way up and onto Skyline from Ephraim is really high summer into early fall, and a high clearance vehicle is the right tool for the rough upper miles.

The details

WhereThe top of Ephraim Canyon, where it joins Skyline Drive
ElevationNear 10,000 feet at the junction; the plateau tops near 10,900
SeasonSnow free only from about mid July into fall
VehicleHigh clearance for the rough upper canyon
MoreThe full plateau is on the Central Utah Skyline Drive page

Getting there

Follow Ephraim Canyon Road all the way up past Lake Hill and the station; the grade steepens and the surface roughens before the road tops out at the Skyline junction. Allow plenty of time, since it is a slow gravel climb rather than a quick drive.

Before you go

  • The upper canyon and Skyline are high country; snow lingers into July and returns early, so check conditions first.
  • This is not a maintained highway up top, so carry water, a spare and a paper map.
  • The plateau, its trails and its OHV routes are covered on the region Skyline Drive page.
  • Turn around at Lake Hill if the road above is wet, muddy or snowbound.

How people use the canyon

Fall color Fishing OHV Winter snowmobiling

Through the year Ephraim Canyon does several different jobs. In summer it is the cool escape: fifteen minutes to the reservoir, camping at 8,400 feet, trout on the line and a picnic under the aspens while the valley bakes. It is also one of the main street legal routes for ATVs and side by sides to climb onto Skyline Drive and the wider Arapeen trail system that laces the plateau.

The canyon's best known season is fall. The aspens that fill the middle of the canyon turn gold in late September, and the drive up to the reservoir and beyond becomes one of the easiest fall color runs in Sanpete County. It makes a short, scenic loop of a morning: up the canyon into the color, out onto the edge of the plateau for the view, and back down to town.

In winter the road is not plowed above the reservoir. Instead the upper canyon becomes a groomed snowmobile route, part of the plateau's winter trail network, with riders using Ephraim Canyon as one of the climbs up to the snowbound top. Hunters use the canyon in the fall seasons as well. Whatever the month, the pattern holds: the lower canyon is the easy, all season part, and the top is the seasonal, high country part.

The details

WhereUp and down Ephraim Canyon and onto the plateau
SummerReservoir, camping, fishing, cool air
FallGold aspens in late September; the color drive
OHVA main access to Skyline Drive and the Arapeen system
WinterThe upper canyon groomed for snowmobiles, not plowed

Getting there

All of it starts on Ephraim Canyon Road east of town. How far up you go depends on the season and your vehicle: pavement to the reservoir in summer, dirt to the top in high summer, and a snowmobile in winter.

Before you go

  • Fall color peaks around late September and is weather dependent, so aim for a clear day.
  • ATV and OHV riders should read the region Skyline Drive page for the trail network and the rules.
  • The upper canyon is unplowed in winter and used by snowmobiles, so do not drive a car past the plowed end.
  • Check the hunting seasons in the fall if you plan to hike or ride.

The logistics


Distances, seasons, and what it costs.

The main stops up the canyon in one table, in order from the valley floor to the plateau. Distances and drive times start from town and are rough planning figures on a mountain road, not exact numbers. Seasons and fees shift year to year, so confirm campground and program details with the Forest Service and Snow College before you go.

The stop Where From Ephraim Season Cost

Skyline Drive, the topTop of the canyon, near 10,000 ftSlow gravel climbMid July into fallFree
Over the top to OrangevilleEast across the plateauA long crossingSnow free months onlyFree

Paved and easy

The lower canyon is paved to Lake Hill Reservoir, so a regular car reaches the water, the camping and the fishing in dry summer weather. That first five miles is the part most people use.

High and seasonal

Above the reservoir the road turns to dirt and climbs to near 10,000 feet at Skyline Drive. That top stretch is snow free only from about mid July into fall and wants a high clearance vehicle.

Mostly free

The drive, the day use and the views cost nothing. Only camping carries a fee, a Great Basin Station program has its own charge, and a Utah license is the one extra cost if you fish.

Preparation


Using the canyon, by season.

Ephraim sits at about 5,500 feet and the top of the canyon is near 10,000, so the same drive lives in two climates at once. Three things shape a trip: how far up the pavement takes you, the short snow free window on top, and the fact that there are no services once you leave town.

The upper canyon is high country, not a maintained highway. Snow lingers at the top into July and the first storms close it again by late fall, and in winter the road above Lake Hill Reservoir is unplowed and groomed for snowmobiles instead. There is no fuel, no store and thin cell signal once you leave Ephraim, and a high clearance vehicle is the right tool for the rough upper miles. Turn around at the reservoir if the road above is wet, muddy or snowbound.

In summer

  • Pavement reaches Lake Hill Reservoir, so a regular car handles the cool air, the fishing and the camping
  • At 8,400 feet the nights stay cold, so pack layers even in July
  • Weekends fill the reservoir and campground; a weekday morning is quieter water
  • The top opens by about mid July for the drive onto Skyline Drive

In fall and winter

  • The aspens turn gold in late September, the canyon's headline season
  • The first heavy storms close the top for the winter, often by November
  • Above the reservoir the road is unplowed and groomed for snowmobiles
  • Fall hunting seasons bring traffic to the canyon; wear bright colors if you hike

On the road

  • No fuel, no store and thin cell signal past the edge of town
  • High clearance helps above the reservoir; the dirt turns to mud after storms
  • Carry water, a spare and a paper map for the upper canyon
  • Watch for cattle, riders and OHVs sharing the road in the warm months

The season, top to bottom

The two ends of the canyon keep different calendars. The lower, paved miles to Lake Hill Reservoir open early and stay usable through much of the year, closing only when a big storm buries the road. The top, near 10,000 feet, runs on a short mountain season: it usually does not clear of snow until about mid July, late September rains can turn the dirt to a bog, and the first heavy snows shut it again for the winter. Plan a full drive onto Skyline for high summer into early fall, and keep the reservoir as the reliable fallback the rest of the year.

One road, three landscapes

Ephraim Canyon changes character as it climbs, and it helps to keep the three parts straight. At the mouth it is farm valley and scrub oak, a few minutes from Main Street. In the middle it is aspen and evergreen around a stocked reservoir, the summer and fall heart of the canyon. On top it is open alpine plateau at Skyline Drive, a different world of wildflowers, long views and short seasons. The same road is a town errand, a family outing and a high country adventure depending on how far up you drive.

Put it together


A quick drive up, or the whole crossing.

Four ways to spend the time you have. The first three suit late spring through fall; the last is the high summer plan, when the top is finally clear of snow.

A short drive up

  • Drive the paved miles up to Lake Hill Reservoir
  • Fish from the bank or float a canoe on the lake
  • Picnic under the aspens and be back in an afternoon

A summer day

  • Camp beside the reservoir at 8,400 feet
  • See the historic Great Basin Station up the canyon
  • Drive toward the Skyline junction if the road is dry

A fall color drive

  • Go in late September for the gold aspens
  • Climb into the color and out to the plateau edge
  • Take in the valley view and drop back to town

Over the top

  • Drive all the way up to Skyline Drive in high summer
  • Cross the plateau and down the far side to Orangeville
  • A long high clearance day; carry water and a spare

Common questions


Ephraim Canyon, answered.

Ephraim Canyon is the mountain canyon directly east of Ephraim, Utah, in the Manti-La Sal National Forest. Ephraim Canyon Road leaves US 89 at the south end of town and climbs east, gaining close to a mile of elevation past Lake Hill Reservoir and the historic Great Basin research station before it meets Skyline Drive on top of the Wasatch Plateau. From there it carries on over the plateau and down toward Orangeville in Emery County.

The lower canyon is paved, and a regular car can reach Lake Hill Reservoir, about five miles up, in dry summer weather. Higher up the pavement gives way to a graded dirt Forest Service road that gets rough and slow, so a higher clearance vehicle is the right tool for the climb to the top. There is no fuel or service up the canyon, so fill up in town first.

The top is high country near 10,000 feet, so the season is short. The upper canyon and Skyline Drive usually do not melt out until about mid July, late September storms can turn the dirt to mud, and the first heavy snows close the top again for the winter. Plan a full drive to the Skyline junction for high summer into early fall, and check conditions before you go.

Yes. Lake Hill Reservoir, a small man made lake about five miles up at 8,400 feet, is stocked by the Utah Division of Wildlife Resources with rainbow and tiger trout, and it fishes well from the bank or a small boat. A Utah fishing license applies for anyone old enough to need one. The mountain streams in the canyon hold trout as well.

It is a historic federal research station set up in 1912 to study the summer floods that were damaging the valley farms after the plateau was overgrazed. First called the Utah Experiment Station and later the Great Basin Experimental Range, it is regarded as one of the places where the science of range management began. Snow College took over the site in 1992 and runs it today as the Great Basin Environmental Education Center.

Yes. Lake Hill Campground sits beside Lake Hill Reservoir about five miles up the canyon, a Forest Service campground with single and group sites, vault toilets and drinking water. It runs a summer season, opening around May and closing in September, and sites can be reserved on Recreation.gov in the busy months. At 8,400 feet it stays cool through the summer.

The aspens through the middle of the canyon turn gold in late September, which makes the drive up to Lake Hill Reservoir and the edge of the plateau one of the easiest fall color runs in Sanpete County. Peak color shifts a little each year with the weather, so go on a clear day toward the end of September.

Yes. Ephraim Canyon is one of the main street legal routes for ATVs and side by sides to climb onto Skyline Drive and the wider Arapeen trail system that runs along the Wasatch Plateau. The trail network, its map and its rules are covered on the Central Utah Skyline Drive page rather than here.

At the head of the canyon the road meets Skyline Drive, the high road that follows the spine of the Wasatch Plateau near and above 10,000 feet, with long views over the Sanpete Valley and the Emery County canyons. Skyline Drive belongs to many towns and is covered in full on the region Skyline Drive page; Ephraim Canyon is one of the main ways up onto it.

Scott Buehler, Moving Utah

A canyon at the edge of town, and a valley worth a longer look.

A drive up to a reservoir and a research station is the visitor's Ephraim, not the resident's. The resident's questions are different: which streets sit closest to the canyon mouth, what a lot costs on the east edge of town, and how the college and the mountain seasons shape a week here. Tell me what you are weighing and I will introduce you to a Sanpete County partner agent who knows this valley, and stay on the file for the research and the financing side.
