“Technical elevated rock sections at the top open up into fast, flowy trail that ends in a chunder'd out creek bed!
— Jeff Simcoe
Chunder Mountain Trail begins at the same area as Gene's Trail
(Fike Mtn Rd.) and ends in the creek bed at the bottom of the Big Bear downhill (Race Loop downhill). It starts out with some classic Big Bear rock features (including a tight canyon/crack type move) then gets fast and rough with the roughest part being toward the bottom. This trail tends to be wet as you get farther down the trail.
