Tom's Thumb Trail was not designed or built with mountain bikes in mind. Due to the number of steep switchbacks and their extremely tight radius, it is a frustrating trail to try to on your bike. Not impossible by any means, but most riders will spend significant portions of the trail hiking their bike. If you are still convinced that you want to bike it, try it as a hike first and then make your decision.

Access Info

Trail can be accessed from the west side via Desert Parks or Windgate Pass Trail. On the east side, access via East End Trail.
