Currently, none of the downhill mountain biking at Snow Summit takes place on the Snow Summit property (although that might be changing in the near future). However, there are a number of gravity-oriented trails spread throughout the nearby San Bernardino National Forest that can be accessed from the top of the lift via the gravel road network.
Some trails are easier, others are more difficult, but on the whole the singletrack is steep, loose, and rocky. If you're looking for an easier ride down, try some of the gravel roads out, or head way outside of the resort and pick up the Pine Knot trail. There are a few jumps and drops that have been built with the help of fallen trees, but if you're looking for an A-line style trail with berms and table tops, Snow Summit doesn't have it. But if you like to pin it through the gnar, come and check out the steep trails above Big Bear Lake!
