Outdoors and the canyon survey Grantsville

The canyon into the Stansburys

South Willow Canyon and Deseret Peak

Grantsville sits at the foot of the Stansbury Mountains, and South Willow Canyon is the way in. The canyon road follows Willow Creek up through five small Forest Service campgrounds, holds pavement to the forest boundary, then turns to gravel for the final four miles to the trailhead. From there the ground rises to Deseret Peak, at 11,031 feet the roof of the range and of Tooele County, inside a wilderness Congress drew in 1984. This is the whole canyon, top to bottom, plus the reservoir on the valley floor below it.

The short answer

South Willow Canyon is Grantsville's own way into the Stansbury Mountains, a few miles southwest of town. A road runs up it beside Willow Creek, passing a chain of small Forest Service campgrounds that climb from oak and juniper into fir. The pavement gives out at the forest boundary, and about four miles of gravel end at the Loop Campground trailhead, the launch point for the hike up 11,031-foot Deseret Peak. Everything above the trailhead is the Deseret Peak Wilderness, no vehicles allowed. It is a warm season canyon; snow closes the high end for half the year.

The drive up South Willow Canyon

Southwest of Grantsville Along Willow Creek Into the Stansburys

From Grantsville you aim for the mountains southwest of town, and within a few miles the valley grid hands off to South Willow Canyon Road, which threads into the mouth of the canyon. Willow Creek runs beside you the whole way up, and the walls close in as the road gains height. The forest shifts as you climb, from Gambel oak and juniper down low into cottonwood, maple and fir higher up, so the shade deepens and the air cools the farther you go.

The road is paved to the forest boundary, and it is an easy, pretty drive that any car can make. The catch waits higher up. Past the boundary the asphalt ends and about four miles of gravel run on to the top, narrow and pinched tight against the creek and the rock. It is passable for a standard car in dry weather if you take it slow, but it is no place for a trailer, and a wet spell turns it greasy in a hurry.

That upper dirt is what carries you to the head of the canyon and the Loop Campground trailhead, where the road quits and the wilderness begins. The entries below work up the canyon in that order: the campgrounds first, then the peak and the backcountry above the trailhead, then the reservoir that sits down on the valley floor.

The Forest Service campgrounds

Intake to Loop Loop takes reservations No drinking water

The canyon's real draw for most Grantsville families is the camping, and it is stacked up the road like rungs on a ladder. Working up from the bottom you pass Intake, then Boy Scout, then Lower Narrows and Upper Narrows, and finally Loop at roughly 7,400 feet at the top of the road. Each is a small, quiet pocket in the trees with the creek close at hand, and the higher ones open later in the season as the snow retreats.

Keep your expectations rustic. These are old Forest Service sites, most of them just a handful of spots with fire rings, tables and a vault toilet, run first come first served, except Loop, which takes reservations. Upper Narrows in particular is primitive, its sites scattered loosely along a mile of road. The one thing every camper needs to know is that none of them have drinking water, so you haul in every drop you plan to use and pack your trash back out.

Because the good spots are few and the canyon is close to the whole valley, summer weekends fill early. A weeknight or the shoulder weeks of spring and fall are the quiet play, and the Loop sites at the top double as base camp for anyone heading up Deseret Peak the next morning.

Deseret Peak and the wilderness

11,031 feet 1984 wilderness From the Loop trailhead

Above the last campground, the ground keeps climbing to Deseret Peak, 11,031 feet at the summit. It is the highest point in the Stansbury Mountains and the roof of Tooele County, and on a clear day the view from the top runs out over the Great Salt Lake, the salt desert and range after range fading west. Everything above the trailhead falls inside the Deseret Peak Wilderness, about 25,500 acres that Congress set aside under the 1984 Utah Wilderness Act, which means no vehicles and no bikes past the boundary, just boots.

The climb is a real one, not a stroll. The standard hike leaves the Loop Campground trailhead near 7,400 feet and gains something like 3,600 feet on its way to the summit, roughly eight to nine miles round trip depending on the line you take. Many hikers make a loop of it, going up by way of the Mill Fork meadows and the south ridge and coming down a different drainage back to the same lot. Give it a full day, start early, and carry more water and warm layers than a valley morning suggests you will need.

This is high, exposed country, and summer afternoons build thunderstorms fast over the ridge, so the summit is a morning goal. Snow lingers on the north-facing pitches into July some years and returns early in fall, which is the other half of why the trailhead is a warm season proposition.

South Willow Lake and the Medina Flat trails

Backcountry lake Medina Flat trailhead On foot only

Tucked high in the Stansburys, off in the wilderness north of the peak, is South Willow Lake, a small alpine tarn most people never see. There is no road to it and no shortcut. You earn it on foot, which is exactly why it stays quiet even on a busy summer weekend down in the campgrounds.

The way in leaves from the Medina Flat trailhead, which sits across the canyon road from the Loop Campground entrance and also serves as the low end of the Stansbury Front Trail. From there the route works up through the Mill Fork drainage into the high country and over to the lake basin. It is a long day out and back, so treat it like the summit hike: an early start, real water and food, and layers for weather that changes fast up high.

The same trailhead leads to the rest of the range's backcountry, so it is worth knowing about even if the lake itself is more than you want to take on. The Stansbury Front Trail traces the foot of the mountains for miles, opening up shorter walks and longer ridgeline days from the very same parking area.

Grantsville Reservoir on the valley floor

About 15 minutes southwest of town County campground Open year round

Not everyone wants the climb, and the canyon has a low-country companion. Grantsville Reservoir sits about 15 minutes southwest of town, reached by heading southwest out of the grid rather than up into the mountains, though it draws its water off the same South Willow Creek that feeds the canyon. It is the flat-water counterpart to the peak: a place to put in a boat, drop a line, or camp within easy reach of home.

The fishing is the point. The reservoir is stocked with rainbow trout by the state through the year, and it also holds smallmouth bass, which must be kept. Tooele County runs the shoreline as a year round recreation area with camping for a daily fee ($20 a vehicle), but keep the same rule in mind as the canyon: bring your own water, so come stocked.

It is a working desert reservoir, not a manicured park, and the water level rises and falls with the season and the runoff. On a hot weekend it is busy with valley families; on a weekday morning in the off season you may have the bank to yourself.

Two kinds of water


The canyon or the reservoir, and which suits the day

Grantsville has two outdoor draws pulling from the same creek, and they ask for different days. South Willow Canyon is the mountain, all shade, trails and the climb to the peak. Grantsville Reservoir is the flat water down on the valley floor, built for fishing and an easy overnight. Here they are side by side, so you can pick before you pack the car.

The spot From Grantsville The road Season Best at
South Willow CanyonSouthwest to the StansburysPaved, then gravel near the topWarm months onlyCamping, trails and the Deseret Peak hike
Grantsville ReservoirSouthwest of townPaved to the shoreOpen year roundFishing, boating and close-in camping

One climbs, one stays low

The canyon is about gaining height, from shaded campgrounds to an 11,000-foot summit. The reservoir keeps you on the flat by the water. Choose the canyon for the hike, the reservoir for the fishing.

Neither has drinking water

Both places have vault toilets and no potable water, so you haul your own to either one. The canyon sites are national forest; the reservoir is a Tooele County recreation area.

Winter splits them

The reservoir stays open through winter and even draws ice anglers, while the canyon shuts down with the snow. When the mountain is closed, the low water is still in play.

Preparation


Reading the road, and reading the season

This is a small mountain canyon, and it rewards a little planning. The two things that catch people out are the rough upper road and the short season. Get both right and the day runs smooth.

The upper road is narrow, unpaved and only open in the warm months. South Willow Canyon Road is paved to the forest boundary, but the last four miles to the trailhead are gravel, tight and squeezed between the creek and the rock. A standard car can manage it slowly when it is dry; it is no place for a trailer, and rain turns it slick. Snow shuts the high end of the canyon for roughly half the year, and road work or a rockslide can close it with little notice, so check current conditions before you drive up and do not assume last week's open road is open today.

On the road

  • The last miles are narrow dirt with potholes; take them slow
  • A standard car is fine in dry weather; rain makes it greasy
  • Leave the trailer at home; the upper canyon is too tight for it
  • The road is single lane in spots, so yield and watch for oncoming cars

On the mountain

  • Carry all your own water; no campground here has a tap
  • The peak is high and exposed; pack layers for wind and cold at the top
  • Summer storms build fast over the ridge; summit early and turn back for lightning
  • Signal drops in the canyon; download your map before you leave town

By season

  • Late April to early May: the campgrounds usually open as the snow leaves
  • Early summer: the upper road clears and the Deseret Peak trailhead comes in
  • Fall: cool air and quiet sites, but the first storms can close the top
  • Winter: the canyon shuts down; the reservoir stays open on the valley floor

Why there is no water at the sites

The South Willow campgrounds are old, simple national forest sites, kept deliberately basic rather than plumbed. There is no water system in any of them, at the reservoir either, so the standing rule for the whole area is the same: bring every drop you will drink and cook with, and carry your trash back out. Willow Creek runs right there, but treat it as scenery, not a tap, unless you filter it.

Where the road stops and the wilderness starts

The dirt gives out at the Loop Campground trailhead, and that is not just the end of the pavement, it is a legal line. Everything above is the Deseret Peak Wilderness, where no vehicles, bikes or motorized gear are allowed. So the canyon divides cleanly: cars, campers and coolers below the trailhead, boots only above it, all the way to the summit.

Put it together


A summit push, a camp night, or a morning by the water

Three ways to take the Stansburys, scaled to how much day you have. The first is a serious hike; the other two are easy to fit around a normal weekend.

A full day up Deseret Peak

  • Drive the dirt to the Loop trailhead at first light
  • Climb the loop past the Mill Fork meadows to the summit
  • Off the top before afternoon storms build

A night in the campgrounds

  • Grab a first come site along the creek, water packed in
  • A fire ring, deep shade and cool mountain air
  • Wake up at the trailhead if the peak is the plan

A morning at the reservoir

  • Head southwest to the reservoir with the rods
  • Fish for stocked trout or launch a small boat
  • Works year round, even when the canyon is snowed in

Living near the Stansburys


The town at the foot of the range

Grantsville spreads across the western edge of Tooele Valley, and the Stansbury Mountains are the backdrop to it, close enough that the canyon is a short errand rather than an expedition. The oldest streets sit on the pioneer grid near Main, and toward the mountains the parcels open up, with larger lots and acreage tracts along the foothills where the ground rolls toward the range. For anyone weighing this side of the valley, the draw is plain: a working town with a wilderness trailhead almost within sight of the porch. The pages below carry the rest of the Grantsville picture, from the history to the everyday to the drive-time math of moving here.

Quick answers


South Willow Canyon, answered

South Willow Canyon cuts into the Stansbury Mountains southwest of Grantsville, on the west side of Tooele Valley. From town you head out toward the range, and South Willow Canyon Road runs up the mouth of the canyon into the Uinta-Wasatch-Cache National Forest.

Mostly. The road is paved to the forest boundary, then about four miles of gravel lead to the trailhead. That upper stretch is narrow and too tight for trailers, though a standard car driven with care handles it in dry weather.

Deseret Peak stands 11,031 feet, the highest point in the Stansbury Mountains and the high point of Tooele County. It anchors the Deseret Peak Wilderness, roughly 25,500 acres set aside by the 1984 Utah Wilderness Act.

The standard route starts at the Loop Campground trailhead at the top of South Willow Canyon Road, near 7,400 feet. It gains about 3,600 feet over roughly eight to nine miles round trip to the summit, and many hikers run it as a loop up the Mill Fork side and down the other. Plan on a full day and an early start.

Yes. Five Forest Service campgrounds line the canyon road: Intake low down, then Boy Scout, Lower Narrows and Upper Narrows, and Loop at the top by the trailhead. They are small and rustic, with vault toilets and no drinking water, so pack in your own. Loop takes reservations.

The canyon is a warm season place. The campgrounds are usually open from late April or early May to the end of September, and snow can keep the upper road and the Deseret Peak trailhead closed later into spring. Road work and the occasional rockslide can shut the upper canyon with little notice, so check conditions first.

South Willow Lake is a small backcountry lake tucked high in the Stansbury Mountains inside the Deseret Peak Wilderness. There is no drive to it. Hikers reach it on foot from the Medina Flat trailhead by way of the Stansbury Front Trail and the Mill Fork drainage, so it is an all day effort, not a roadside stop.

Grantsville Reservoir is stocked with rainbow trout by the state through the year, and it also holds smallmouth bass, which must be kept. It sits about 15 minutes southwest of town, run by the county as a year round campground for a daily fee. Bring your own water.

The mouth of the canyon sits just a few miles southwest of Grantsville, so the lower campgrounds are a short drive from town, roughly fifteen to twenty minutes to where the pavement ends. The Deseret Peak trailhead takes about 35 to 40 minutes, because the final miles are slow going.

Scott Buehler, Moving Utah

The trailhead is the draw, the town is the decision

Anyone can drive up South Willow Canyon for a weekend. Choosing to live at the foot of it is a different question: which part of Grantsville sits closest to the mountains, how the acreage parcels near the foothills compare to the old grid near Main, and what the commute out of the valley really costs. Tell me what you are working through and I will hand you to a Tooele Valley partner agent who knows this ground, then stay involved on the research and the loan side myself.
