This trail is tucked in between the Red Trail and Blue Trail in Bay Park West. It's good, flowy hand-built singletrack that winds around the bowls.
Orange Trail begins at the top of the Blue climb from the trolley bed, where Blue, Red, and Orange split. Orange is the middle route, uphill of Red and downhill of Blue. It briefly runs on its own before rejoining the other two for the rocky creek crossing. It continues right with Blue past the split with Red and then splits left from Blue.
From there, there are no trail intersections until its end at the big saddle and 4-way intersection with Purple Trail and Blue Trail. Orange Trail winds up and down the bowls through the woods. The last portion of Orange is fairly new (finished in Fall 2014) and is extra rolling, like a pump track. Like most other trails in West Bay, enjoy it in both directions!
