Only a 20 minute boat trip from the mainland, Skomer is an excellent place for a daytime adventure. Bursting with seabirds including our Atlantic Puffins, Guillemots and Razorbills, this National Nature Reserve is one of Britain's most important seabird colonies. It is peaceful and wild at all times of year - there's so much to see and explore.

Please note, Puffins start arriving in mid-April. They are present from May-July. The first ones start leaving in mid-July and all Puffins are gone by the end of July. Please see our seasonal timeline below for what to see each month.
