Overview
The upper Fremont River corridor is one of the most accessible and scenic canyon walks in Fishlake National Forest. The trail follows the river downstream from a USFS access point on UT-24, staying close to the water through a classic southern Utah setting of red-rock walls, cottonwood trees, and clear-running river. The grade is gentle throughout, making this a strong option for hikers who want riparian scenery without serious elevation work.
The route also serves fly fishers, who know this stretch of the Fremont as a quality brown and rainbow trout stream. Multiple dispersed camping areas sit along the river corridor, and the combination of easy access and good fishing makes this one of the busiest riparian zones in the forest, though "busy" here is relative: on most weekdays you may share the trail with only a handful of other visitors.
The Route
Trailhead to First River Bend (Miles 0-1.5) The trail follows the river's north bank immediately from the trailhead, staying within earshot of the water throughout. The first 1.5 miles pass through open cottonwood flats with several dispersed camping spots visible across the river. The path is well-worn and easy to follow.
Canyon Narrows (Miles 1.5-3.0) After the first major bend, the canyon walls close in and the trail becomes more defined by the terrain. The river picks up velocity through this section, and there are several good casting pools for fly fishing. The red sandstone walls rise 100 to 200 feet above the river in the narrowest section.
Upper Flat (Miles 3.0-3.3) The canyon opens into a broader flat at the upper end of the maintained trail section. A large dispersed camping area sits here, and the river slows to a meandering stretch through willows. This is the turnaround for the out-and-back. The trail continues as a rough path beyond this point, but becomes unmaintained. Return the way you came.
When to Hike
May and June offer high river flow from snowmelt and excellent spring birding along the riparian corridor. The trail may have muddy sections near the water in early May.
July through September the river drops but remains fishable. Temperatures in the canyon can be warm by afternoon. Start early and carry ample water since the river water requires treatment.
October brings cottonwood fall color and the end of fishing season for many anglers. The trail is dry and firm, and the canyon walls glow in the lower-angle autumn light.
What to Bring
Many hikers and anglers carry 1.5 to 2 liters of water since river water must be treated before drinking. A fishing rod and Utah license make this trail significantly more rewarding for anyone interested in trout fishing. Rubber-soled boots help on the rocky river edge. A light rain layer is useful in afternoon monsoon season. Individual water needs vary by pace and conditions.
Trailhead Access
The trailhead is off UT-24 east of Loa, Utah. The parking pullout has a vault toilet and space for 8 to 10 vehicles. No day-use permit or fee is required as of 2026. Dogs are welcome on leash. Cell service is not available from most carriers in this canyon. The nearest full services are in Loa (gas, limited supplies) and Richfield (full services).
