On inclement days thunderous waterfalls of rain run-off spill over the cliffs and into Dungeon Hole. Some of them seem to issue from out of the cliffs themselves, with no obviuous water source above but most have a channel of water at the top. This section of coast, up to Ness Point, is rich in rare ammonite species.

Coracles are a simple means of gettng around over difficult water terrain such as are found at low tide at Dungeon Hole. Rare ammonites can be found here, and some parts of the Bay's dome have scores of coracle tourists. Coracles are small light-weight one-man boats.
