Zig Zag is very tight, twisty, and a bit rough. Start at the parking lot and enter the woods next to the kiosk. Zig Zag is marked by a wooden sign just on the other side of the bridge. Once you are on Zig Zag the trail get tight and twisty. It skirts the westside of the parking lot and makes its way towards west boundary road before making a right turn and paralleling West Boundary Road.
At the edge of Purdham Hill, Zig Zag turns away from West Boundary road and criss crosses the pipeline until it intersects with Shipwreck
near 5Mile. The trail is tight and and a little rough the entire time.
