New Trails Added to Avalanche Trail System
TOMMBA has completed the construction of the final trail in the Avalanche Multi-Use Trail System, and it is open to all riders. The trail is called Stroll the Steep and is an Advance Level trail designed to be ridden in one direction, down. The trail is the most difficult within the trail system, and should be ridden with caution. This trail IS NOT for beginners. Access to the trail is gained by riding one of the "legacy trails" that has been named Bo-Riginal. See the map below.
