Mupe Bay is an incredibly dramatic pit stop along the Jurassic coast. Surrounded by steep cliffs dropping off (in some cases quite literally) down to shingled beaches which extend out into crystal clear water and then a bed of sand.
The holding was good although the anchorage was quite busy. There's a lot of luck involved in getting into Mupe Bay, as you can only venture in when the military firing ranges are not in action, so you will have to check with the ranges themselves here.
Like Lulworth Cove, Mupe Bay gives you good protection from the North, but nothing from the south. You also want to be mindful of potential catabolic winds which can rip down off of the cliffs and into the anchorage.
