Details like bobbing out through a passageway from a bowl-like cave to play with seals – just another day when coasteering from Morfa Nefyn, says Chris Thorne, founder of Llyn Adventures. With its low 10m cliffs, the north coastline of the Llyn is accessible to all. For adventure there’s Aberdaron: the waves are larger, the coasteering wilder.
