there's some stuff. not much, but snapper is worth a play – just a short little dh-y track, probably in terrible condition at the moment though. head out of barny on the goodleigh road (bear street?), keeping left at the goodleigh fork. through the village of snapper, and then after a bit you'll come to a left hand turn over a little bridge. park almost immediately and follow the fireroad up. the track takes a little finding, but there's some other stuff in the woods. nothing worth writing home about.
if you were down for longer, there's loads of worthwhile stuff north of braunton but it takes a lot of finding and a fair amount of roadwork to link up.
