Bells Canyon does not see much Mountain Bike traffic, and for good reason! It starts out very steep and with a loose gravel trail base, it makes for a tough climb on a bike. There are steps that are all but impossible to ride up (or down). After reaching the very scenic Lower Bells Canyon Reservoir the trail is much better! It turns to a fun single track through the trees. After crossing the stream above the Reservoir the trail becomes snarled with large granite boulders and is tough for even a hiker to negotiate.
