Make no mistake: the grunt to the top is still strenuous. But that steep climb rewards you with a superb descent!
The descent begins with beautiful ridge top riding, with wide-open views in all directions. The soil is sandy and loose, interspersed with sharp rocks that look volcanic in origin.
After dropping off the ridge, the descent picks up in earnest, with some portions of the trail being bench cut into the side of the mountain. The fall danger is quite significant through the bench cut sections—while the trail tread is wide, it would be a long tumble down the mountainside!
Lower down, the steepness of the mountain slope mellows out, allowing you to really open it up and rail through the flowy, dry singletrack! In the middle portions of the trail, the singletrack swoops through wide-open alpine meadows.
Eventually, this flowy track drops back into the forest. Some of the lower sections of the trail actually hold bigger rocks and gnarlier rock gardens than the above treeline portions. Here, the rocks are more rounded and boulder-like, with a few big up-and-over moves.
There are a few different ways to climb and descend Thunder Mountain. The route mapped here includes a little car shuttle via the highway to get you some free vert. Alternatively, you could pedal up the highway, ride from the upper trailhead as an out-and-back, or if you’re truly masochistic, ride up from the lower trailhead.
However you choose to ride it, Thunder Mountain serves as a rewarding and surprisingly-rideable mountain summit.
Widely variable, narrow trail tread with steeper grades and unavoidable obstacles of 15in/38cm tall or less. Obstacles may include unavoidable bridges 24in/61cm wide or less, large rocks, gravel, difficult root sections, and more. Ideal for advanced-level riders.
