Boscastle, Devon

Much of the land in and around Boscastle is owned by the National Trust.
The village is of course famous for nearly becoming an ex-village during a disastrous flood a few years ago. At the village centre you can visit a small museum of the disaster and look at the new bridge and flood prevention works. It’s worth making an effort to tramp further afield, as there are interesting walks down to the harbour mouth (both sides), or if you can find a paper walk guide, you can walk around some hilly old streets looking at old buildings of interest. The harbour largely dries out at low tide.
