Easily accessible from Interstate 80, the Castle Peak area is a popular destination for summer hiking and winter snowshoeing or backcountry skiing. It is in the Tahoe National Forest not far off the Pacific Crest Trail, and adjacent to Castle Pass.
Directions:
Take the Castle Peak/Boreal exit off I-80 and park at the lot on the north side of the freeway, then proceed about 1.5 miles along a dirt road to access a web of hiking, biking and cross-country ski trails at the base of Castle Pass. From here, you can ascend to the 9,103-foot Castle Peak summit or follow the Pacific Crest Trail into Round Valley, where you can visit the historic Peter Grubb hut.
