Armstrong Pass is a 22.6 mile lightly trafficked loop trail located near South Lake Tahoe, CA that offers scenic views and is rated as difficult. The trail is primarily used for hiking, trail running, and mountain biking and is accessible from June until October.
Tough hill climb but going up you can take the paved road to the beginning of Armstrong and then fly down. Great trail coming down. I had a blast with Corral trail at the bottom. Lots of jumps and curved banks.
