I like this site a lot - three lads having a right laugh messing about. I've done a day of "coasteering" with a mate in South Wales and it was wicked fun - well recommended for maximum fun.

what do you actually have to do? is it a case of traversing the headland just above the sea or something?

[Bubba]

Yeah, it's just messing about above the water, so lots of traversing, jumping, sometimes swimming and stuff - we got really close up to seals and stuff too which was nice but then we wimped out of a particularly ominously looking bit of water with a gnarly looking whirlpool in it.

google turned up this history of coasteering http://www.farmersmathry.com/page14.html

One of the better known routes is Magical Mystery Tour, HVS 5a, 7,700ft at Berry Head, and really the modern deep water soloing is the same thing taken in a different direction...up!
