Overview
Mount Elmer rises from the limestone ridges of Logan Canyon in Cache National Forest, offering one of the more demanding and solitary summit hikes in the northern Wasatch. The 7.2-mile out-and-back gains 2,200 feet from the Sink Hollow Trailhead to a summit at approximately 9,660 feet with outstanding views of Logan Canyon, Cache Valley, and the Bear River Range.
The trail is considered strenuous, with sustained climbing through aspen and conifer forest before emerging onto the open limestone ridge. The upper sections involve some route-finding on faint trail across rocky terrain, making this a better choice for experienced hikers comfortable with basic navigation.
The Bear River Ridge Trail in the same area offers a loop alternative for those who prefer not to retrace steps.
The Route
From the Sink Hollow Trailhead, the trail climbs steadily through dense forest for the first two miles. A trail junction at the ridge top requires staying right to continue toward the summit. The ridge walk to the summit covers about a mile of open terrain with increasingly expansive views.
The summit area is rocky and exposed. On a clear day, the Great Salt Lake is visible to the southwest and the Bear Lake basin to the northeast.
When to Visit
July through October is the reliable window. Snow can persist on north-facing slopes into early July. Afternoon thunderstorms are common in midsummer; an early start is advisable. Fall visits in September and October offer great weather and near-empty trails.
Practical Details
No facilities at the Sink Hollow Trailhead. Carry all water from home. Dispersed camping is permitted on Cache National Forest lands away from the trailhead. Review Leave No Trace principles before visiting. The 10 Essentials are important on this more remote route.
Getting There
From Logan, drive east on US-89 through Logan Canyon. Approximately 12 miles from the canyon mouth, watch for the Sink Hollow pullout on the north side of the highway. The trailhead is not prominently signed; a GPS waypoint is helpful.
Leave No Trace
This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.
