Overview
Steam Mill Lake Loop is one of the quieter day hikes in Cache National Forest, tucked into the forest east of Logan Canyon and away from the heavily visited Tony Grove corridor. The 5.6-mile loop visits a secluded backcountry lake through mixed aspen and conifer forest with a modest 800 feet of gain.
The trail is rated moderate and represents a good middle ground: more than a lakeside stroll but without the sustained climbing of routes like Naomi Peak or Bear River Ridge. Wildlife is a highlight: moose use the wet meadows near the lake, and mule deer are common throughout the forest.
The Route
The loop can be hiked in either direction. Taking the left fork from the trailhead climbs gradually through forest before reaching the lake at about 2.5 miles. The return completes the loop on the south-facing slope through open aspen groves. The lake sits in a shallow bowl with views to the ridges above.
When to Visit
June through early October. The aspen groves are spectacular in late September, making this a popular fall hiking destination. Summer mornings offer the best wildlife viewing. Afternoons in July and August can see passing thunderstorms.
Practical Details
No facilities at the trailhead. Dispersed camping is permitted on Cache National Forest lands. Review Leave No Trace principles for backcountry camping. Carry all water or plan to treat from the lake.
Getting There
From Logan, drive east on US-89 through Logan Canyon. Turn onto the appropriate forest road as marked by trailhead signage roughly 15 miles from Logan. The turnoff is easy to miss; download GPS coordinates before departure.
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.
Safety Considerations
The moderate rating reflects the trail's general character under typical conditions. Weather, seasonal snow, and trail conditions can change the experience significantly. Carry the 10 Essentials on any full-day outing. Inform someone of your plans and expected return time before heading out, particularly on longer or more remote trails. Cell service varies throughout Cache National Forest and may be unreliable in canyon bottoms or remote terrain.
