Off Anglesey's eastern point, the Special Protection Area of Puffin Island is alive with puffins, cormorants and kittiwakes, while seals, porpoises and dolphins call the waters around the 28-hectare island home. Seacoast's (weather-dependent) 90-minute boat trips cruise alongside the island or through Menai Strait; book at the kiosk at the entrance to the pier or by phone.
