Rainbow Lake Trail


Rainbow Lake Trail - The first part of Caton Lake Trail is the upper portion of Ditch Creek Trail.

Ditch Creek Trail provides access to Rainbow Lake Trail and Caton Lake Trail.

Approximately 0.7 miles from the trailhead, the unsigned 0.3 mile Rainbow Lake Trail splits off to the left. In another 1.8 miles, the trail junctions with the Caton Lake Trail.

From the Ditch Creek/Caton Lake Trail junction to Caton Lake is 5 miles, and another 0.8 miles to the boundary of the Boise and Payette National Forests.

The trail weaves in and out of trees, large open wet areas, and meadows. After climbing slightly, the trail drops gently for several miles. The trail then passes through Caton Meadows, climbs to a low saddle, and drops sharply to Caton Lake.

This trail begins approximately 0.7 miles up the Ditch Creek Trail. It is not signed, but the trail is obvious and takes off to the left. 

Just before the lake, the trail passes through a medium sized campsite, and then out of the trees onto a small marsh at the south end of the lake. Rainbow Lake is lovely and clear, though steep sides and encroaching forest limit the shore.
