Chipperfield Common is a very popular spot for walkers, both 2 and 4-legged. During the summer the woods are very busy but fewer people venture down to this part. I placed it in winter when leaf cover was minimal but even so it was difficult to get a good satellite lock. You should have fun when the trees are in full leaf!
Penman's Green used to be a stop off point while driving the sheep to market. You can still see a small pond used as a drinking spot for the sheep at N 51°41.852', W0°29.779' There is a small bench here where you can rest and also nearby in a clearing at N 51°41.874', W0°29.932' Either would make a nice picnic spot.
The cache is just off a footpath midway between the two. It is in a typical cache hiding spot, well typical for me and will involve a little bit of "ducking and diving" in the last few feet. Nothing too strenuous though and certainly no fences to cross.
The best place to park is in the Church car park right by the village green at N 51°42.203, W0°29.479' This has the advantage of being close to the Two Brewers pub/restaurant and overlooks the cricket pitch. The cache can be reached by taking any of the myriad paths through the woods. Parking is also available in Belsize at N 51°41.821', W0°30,237' (anybody seeking Hornet's Hide 10 might welcome a short break here!)
The cache is a small tupperware style box so please keep swaps small. As with most of my caches there are a number of very good pubs nearby, any of the 4 within half a mile serve excellent food and beer.
During wet weather beware of lots of mud in places due to this being very "horsey" territory.
