The trail itself
One road, and a fence at the top.
The honest way to describe Green Canyon is a wide old road grade that keeps climbing. There is no trailhead sign board with a neat mileage; there is a canyon mouth, a dirt road, and a canyon that narrows and steepens as you go. The Forest Service length, about 4.27 miles for Green Canyon Trail number 000, measures the graded road and trail up to a fence near the head of the canyon, and that fence is the natural turnaround for most people.
You will see the length quoted a few different ways online, from a shorter official figure to a longer round-trip number that counts the walk back. Here is the version that actually helps: most walkers and riders go about four miles up to the fence, climbing somewhere around 1,000 to 1,100 feet, and turn around there. If you want the top, a narrower singletrack of roughly 1.7 miles carries on from the fence to the edge of the Mount Naomi Wilderness, which puts the full push near 5.7 miles each way and closer to 1,800 feet of climb. Pick your turnaround and the canyon rewards it either way.
It is not a technical trail. The grade is steady rather than brutal, the footing is road-solid on the lower stretch, and the first mile or two make a genuinely easy out and back. What changes with distance is the exposure: the upper canyon is remote, shade comes and goes, and the road surface roughens. Carry water, because there is no reliable place to get it, and the canyon's own stream is often dry for reasons worth a paragraph of their own below.
The details
The drive and the seasonal gate
Getting there, and when the gate is shut.
Getting to the mouth is simple. From central North Logan, follow 1900 North east until the houses give way and the pavement ends, about five minutes from Main Street, and you are at the lower trailhead with parking. That lower area stays reachable on foot all year, so a winter or early-spring walk is fine; you just start from the bottom.
Higher up, a gate controls the dirt road, and it is closed through the snow season. Closures run roughly from November 1 into May, driven by snow and mud rather than a fixed calendar, and the road generally opens by about mid-May. That is why the reliable driving and riding season up the canyon is roughly mid-May through October. When the gate is open you can drive farther in, but the road has a rough, washed spot not far up, so a higher-clearance vehicle is the comfortable choice past the gate. Cell signal fades as you climb, so download your map in town.
Two things to plan around. The upper canyon gate is closed through the snow season, roughly November through mid-May, so confirm it is open before you count on driving in. And at the head of the canyon you reach the Mount Naomi Wilderness boundary, where no motorized travel and no mechanized travel, bicycles included, are allowed past the line. Ride and roll up to the boundary, then continue on foot or horseback only.
Who it is for
Hikers, bikers and horses share it.
Green Canyon is a shared-use canyon, and that mix is part of its character. The Forest Service lists Green Canyon Trail number 000 for hiking, mountain biking and horseback riding, and on a decent-weather day you will meet all three: walkers and trail runners on the lower grade, riders climbing to the fence and dropping back, and the occasional string of horses. The wide road grade is what makes that coexistence work, and it is why the canyon is a training-hill favorite for anyone who wants steady vertical close to town.
Motorized use is the one thing to check rather than assume. The trail listing names hiking, biking and horseback riding, and rules on the lower canyon road can change from year to year, so if you plan to ride a machine, look at the current motor vehicle use map or call the Logan Ranger District first. What does not change is the top of the canyon: past the Mount Naomi Wilderness boundary, no motorized and no mechanized travel is allowed, so mountain bikes and any wheeled machine stop at the wilderness edge and the last stretch is foot or horse only.
For a first visit, the lower two miles are the easy introduction, a steady out and back you can shape to whatever time you have. Save the push to the fence and the wilderness singletrack for a morning with water, sun protection and a look at the forecast, since the upper canyon is exposed and remote.
The water pipeline that built the town
Why the streambed is often dry.
Green Canyon is not just North Logan's backyard trail. It is where the town's drinking water came from, and that story is the reason the canyon matters civically as much as recreationally. In the 1920s, families in North Logan were getting sick, some with meningitis, from contaminated canal water, and the wells they drilled came up warm and metallic. The community's answer was to go up the canyon for clean spring water.
The pipeline was finished in 1935. It was led by Orson W. Israelsen, an engineering professor at the agricultural college in Logan, and it was Depression-era work in the most literal sense: partly funded through the Works Progress Administration, partly paid for by the town, and dug by hand. In Israelsen's own account the crews worked with a pick and shovel and crowbar, trenching miles of line down out of the canyon and across the valley floor to North Logan's homes.
That system, rebuilt over the years, is why you will often walk a dry or near-dry Green Canyon streambed even in a wet spring. Modern piping captures the spring flow for the culinary system before it can run the length of the canyon. When you stand at the mouth, you are standing at the head of the town's original water supply, which is a fair thing to know about a canyon most people treat purely as a trail.
