There are no signed trails here, but it's easy to create your own circular walk over the heath and woodland.   We followed a footpath sign just inside the gate by the parking bay, and then went up the hill and followed a fence until we saw a lake further away on the right.  This seems to be a fishing lake, so we avoided that and took a path away from it and into the woodland, gently curving to the left to walk through the trees back to the car.   There's a lot more woodland if you want a longer walk.
