Warren Lake Trail to Frog Lake Cliffs

This hike begins at the castle peak parking lot along hwy 80. Start going north on Castle Valley Road as if going toward the peak, but soon veer east onto the Donner Lake Rim Trail. About 3 miles in, a northern trail with a wooden sign showing it as Warren Lake Trail appears - take this uphill until an overlook offshoot at mile 4. This overlook provides incredible yet under-published views of Frog Lake and Tahoe Donner. Enjoy!The entire route takes place on relatively mellow trails with soft pine and dirt surfaces, with only a few instances of hiking over granite slabs. Shade is plentiful the entire way aside from the last half mile, which is exposed to the sun a wildflower meadow rife with mules ears. This route is an off-the-beaten-path classic largely because it offers solitude, incredible views, and varied trails without the typical traffic, even though it starts from one of the area's most popular trailheads.
