Butterhole is a stunning spot on the north coast of Cornwall. You won't be able to get there by car, you'll have to hike to it. The beach is not suitable for picnics, buckets and spades, or surf boards, as it is surrounded by vertical cliffs and a very steep, ancient sheep path that is only visible to sheep. It's not suitable for kids, pets, or wheelchairs, and there is no parking. It's only for the properly kitted climber or local lunatic. Once you get there, it's so beautiful that it's hard to leave.
