As always, you look for caches at your own risk.
Placed with the kind permision of the landowner - Mr D.L. The recommended way to get to the cache is by walking along the Western side of the hedge and ditch opposite the large barn on Seaside Road - the path pretty well points straight to the cache. Alternatively you can get there from the North, along the cliff top from the stream called the Runnel (past The Forgotten Bridge). Neither are a public right of way but are much used by dog walkers and beach fishermen and allowed by the landowner.
This Second World War Pillbox that was the last one along this section of the coast (and was the host for the original Holmpton Number 19) went into the sea last week as a result of coastal erosion. But there remains, for now at least, the remains of the associated Royal Observer Corps underground monitoring room (long since largely filled in, but with bits of it still sticking out of the ground).
