For qualifiers looking for a little excitement, a new activity is coming into vogue: coasteering. Along the Pembrokeshire Coast of Wales, Preseli Venture specializes in corporate group business and has its own wilderness lodge, located in the U.K.'s only national forest, just a short hike from the rocky Atlantic shoreline.

Suited up in wetsuits, helmets, and buoyancy jackets, groups explore the sea caves of the coast with a guide, sometimes swimming and other times rock climbing. The daring ones in the group also get the chance to fling themselves off the shore's towering rock faces.

The typical excursion is half a day, and the best group size is about 12 people (maximum 20). Preseli's Adventure Lodge is two hours from Cardiff and four hours from London.
