It's a nice walk down Pound Lane to our of our family's frequently visited spots... the "tree house" has seen better days but is in the middle of nice circular walk around the edge of North Crawley. Keep going past gz to Dollars Grove Farm if you want to do the circuit, turn right down the road up to the farm, and then right again through East End down to the main road. Right again for North Crawley.
You can park in the village to start this walk and walk down Pound Lane where the road runs out. Or you can park there if you not having a long walk. Either way you the walk down the semi- tarmacced track until it bears sharp left. You keep straight on through an immature but pretty wood along a marked footpath/bridle way. Follow the path until you get to the edge of the field. Admire the little structure where the cache used to be hidden. Then check the hint because we had to move it a stone's throw away ....
