Route Description for Lewiston Lake Trail

The Lewiston Lake Trail is a family-friendly adventure in the Shasta-Trinity National Forest that boasts picture-perfect scenery. Meander along the shoreline cliffs of the busy body of water and admire the beauty of the inviting waters bounded by rolling hills. On a clear day, you will even notice Mount Shasta looming in the distance. Accessible year-round, our favorite time to hike this route is in the autumn when the foliage is changing. No matter the season, make sure your camera is charged; this stunning trail warrants countless photo opportunities.

Using the trail GPS, the path Lewiston Lake Hike travels north along the shoreline of the Trinity River. As you weave between tree shade and exposed terrain, you will be granted inspiring views of Mount Shasta commanding the northeastern skyline on a clear day. Continue along this route all the way to Copper Gulch. At this point, turn around and retrace your footing along the path back to the trailhead, where you will continue south.

Follow this route past the parking lot and down towards the Mary Smith Campground. At the path’s end, backtrack to the trailhead, marking the end of your adventure.
