Tight switchbacks on extremely narrow single track. Only available to bikes from September 15 to May15! Big elevation loss so really not a great downhill for bikes. It is a very expedient route to get to the top of Mt Constitution when doing an all singletrack look from Mtn Lake, though if you can do so without getting off your bike you're superhuman. Start from the northwest corner of the parking lot just before the Y and under the power line. FYI, want some jumps, stick to the power line trail!


Trail only open during winter months
