There has been a bunch of fun trails built in the Tahoe Donner neighborhood of Truckee in the past few years. We rode a new to us loop that included Cinnamon Twist, Mustang Sally, and Sidewinder.
Jackass Trail is probably the most ridded downhill trail in the Truckee area, and that’s for a good reason. It’s rideable by all levels of riders, with ride arounds for beginners and doubles, drops, and rock rolls for advanced riders. It’s newly legal (thanks Truckee Trails Foundation & US Forest Service!) and there’s a new trail for climbing so go check it out.
