Slickrock Trail
The OG. Petrified sand dunes, painted desert, pure traction on sandstone. A bucket-list ride.
Trail beta
Park at the main Slickrock trailhead inside Sand Flats Recreation Area ($5/day per vehicle, $2 by bike); lot fills on busy weekends so arrive early. Ride the Practice Loop first (right fork at 0.25 mi). If the Practice Loop humbles you, turn around; the main loop is harder. Main loop is ridden clockwise by convention: take the left at the loop junction and climb Swiss Cheese Ridge first. Follow the white painted dashes religiously, yellow = caution, don't cross biological soil crust between domes.
When to go
Open year-round via BLM's Sand Flats Recreation Area ($2 bike day pass). Prime conditions run March-May and September-November when temps sit in the 60s-70s. Summer is dangerous: the exposed sandstone reflects heat and triple-digit surface temps are common, so locals ride at dawn or skip it entirely. Winter is rideable on dry days but can ice up after storms.
