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.

WTSWW’s marine monitoring work gathers evidence for critical datasets, used to strengthen the resilience of Wales’ network of protected marine sites and the protection of the marine species found within these sites. Long-term, uninterrupted datasets are particularly important to assess broad population trends, filling knowledge gaps, and informing decisions about use of the marine environment.
