MNA Coach Trip Cemlyn Bay 23rd June 2012


Sea Kale Growing On Cemlyn’s Shingle Bank

After a brief convenience stop at the loos at Penrhos CP it was off to the second venue for today’s coach trip Cemlyn Bay NR. Cemlyn is known mainly as a valuable site for terns with Common Terns, Sandwich Terns and Arctic Terns seen on the breeding colony – unfortunately no sign of the Roseate Tern that the warden noted.
