Pioneered in Wales, coasteering is a high energy adventure sport involving swimming, rock scrambling, cave-exploring, cliff jumping and other exhilarating actions to traverse a coastal terrain both in and out of the water. The Welsh cliffs and coastline around Pembrokeshire, Anglesey, Glamorgan and the Gower Peninsula are ideal for this kind of adrenaline rush. There are several outfitters in those areas that can arrange full or half day guided excursions that can be geared from novice to expert ability levels, and by all reports it’s an absolute blast. Respect and education of coastal ecology is an offshoot of this pursuit, and safety is paramount. Helmets and wetsuits are provided, but you have to muster up your own courage to take the plunge.
