Purchase a map of Stanislaus National Forest at the ranger station in MiWuk or Pinecrest and also a map of Toiyabe National Forest at the Bridgeport ranger station. One of the favorite trails is Lyons Reservoir – Railroad Grade. It is a 4.5 mi/7.2 km, moderate trail with elevation gain of 200 ft/61 m.
It is a gentle trail to Lyons Reservoir, that follows the old Sugar Pine Railroad grade. In late spring, it is open even at an elevation of 4000 ft/1219 m. Lyons is a beautiful lake to visit. Hike around the lake, it’s on an easy level trail across the dam.
At the south end of the lake is the dam, having a dramatic spill way that drains the lake into a magnificent picturesque canyon below the dam. In late summer and fall the lake drops, as  water is used by the Tuolumne water district.
