Land Owner
Born in the days of old with the newness of the current trails This section of trail has challenged many riders over the years. The rock garden has multiple lines with that range in difficulty from steep rock faces to a full on rock drop. The trail then leads to the refurbished jump section including a wooden drop.
Traditionally Indigenous Territory
