Geology Tour Road is a 16.9 mile out and back trail located near Desert Center, CA and is rated as moderate. The trail is primarily used for hiking and mountain biking and is accessible from October until May.
When I return to Joshua Tree National Park, I want to see Squaw Tank on Geology Tour Road, then drive all the way through Pinto Basin Road to checkout Cholla Cactus Garden, Cottonwood Spring and Lost Palms Oasis Trail. Continue to Cottonwood Springs Road to see Bajada Nature Trail, and finally return to Interstate 10 heading west to see if it’s possible to access Thermal Canyon Road. Passed Geology Tour Road last time and didn’t go all the way because it didn’t look interesting enough, next time will check to discover if it was worth seeing Squaw Tank.
