The climb up Santa Rosa features some tight switchbacks combined with 3-4" boulders that you'll need to lift that front tire over while cornering uphill. Once at the top you are rewarded with some super fast flowy downhill that contains many obstacles in the form of sharp pumas rock and some tight switchbacks which can sneak up on you. It's well worth enduring the short climb.
The right turn onto Santa Rosa Trail.
