Extremely rocky trail that drops off of the top of the mountain. The top of Skid Marks has beautiful views of the lakes basin, but you'd best keep your eyes on this unrelenting trail.

Access Info

Take the Panorama Gondola to the summit. After exiting the gondola building, take a left and go behind the building. The trail splits from Off the Top after about 400 yards.

Adaptive Bike Info
aMTB Black Rating: Advanced obstacles exist, some trail obstructions.

Crossing the exposed pumice field at the top is a little sketchy

        I have a love/hate relationship with Skid Marks. It’s worth doing (at least to mix it up from the top)...
