This is pretty dang cool. "Coasteering" is the latest wacko activity that adrenaline junkies have dreamed up. It originated in Wales and as one coasteer (?) puts it, "it's everything your mother told you not to do by the seaside." Basically, you strap on a helmet and wet suit and work your way down the rocky coastline, however you can. You shimmy around on slick rocks and when it gets too steep or too high, you jump in the water. You get tossed around in tidal pools like you're laundry and dart in and out of caves like a sea turtle.
I'm not Mr. Extreme or anything, but I enjoy a good romp now and then and I love the spirit of these people and how they use the Earth as their own little playground. It reminds me that humans are kind of cool and creative.
