Park on the side of the track leading to Hawk’s Tor Farm. Walk NE past the Trippet Stones, through the first gate and across the small stream. You are now in a narrow lane with sheep pens. There are two more gates in this lane (both were tied shut and I had to climb over them). You can then follow either route to the Stripple Stones (the south route is easier going). The land marked in yellow is private, but I believe this route has been given the OK for access to the stones.
