The last of this little trail, assuming you've started at the west end or have made a circular walk using the old trackbed. Coming along the lane cross the bridge (or wash your boots if you feel brave after rain) then take a rest on the biggest stone bench I've seen on the island. Moving on you will quickly come to Ballaugh village, a good spot for a start/finish to a walk as there is a shop, a pub doing good food and public toilets. Doing the circle gives a walk of about two and a half miles, with three more caches on the route, the circle can easily be extended in either direction using the old MNR track and back roads. There is no need to go onto the TT course, though you are never far from it. 
The cache is a camo'd tube, at the east end of the "bench", ground level.
