Anglesey offers some of the best wildlife watching opportunities in North Wales and if you want to see porpoises, your best bet is to head over to the north side of the island.
You are almost guaranteed to see harbour porpoises (Phocoena phocoena) at Point Lynas during high water. At this time of year you will also see gannets (Morus bassanus) and sandwich terns (Sterna sandvicenis), or maybe even their large resident Atlantic seal (Halichoerus grypus).
The staff at the National Coastwatch Institute hut are a wealth of knowledge and will happily point things out to you.
If you are visiting during September or October, keep an eye out for Risso’s dolphins (Grampus griseus), which can be seen breaching.
Directions: Park in the free car park opposite the caravan site and walk down to the beach. To get to the lookout point, turn right at the beach and walk up the road towards the lighthouse. Follow the path around the side of the lighthouse and you will see the Coastwatch hut and the lookout.
Admission: Free (but feel free to make a donation to the National Coastwatch Institute)
