Jo dearest, it is a wade through 2 or 3 feet (0.5 to 1m in new money) of water for a bit, maybe 50 yards, but the beach itself is worth it. Like Dimitris said in another post it is lovely up north. When the wind/waves are up it can be a bit of a challenge getting there. But the sea yesterday was like getting into a bath. So warm even I didn't even notice. I am certain that you will have all you need, but may be surprised by the change of shape along the whole thing.
