Belmullet Boat Charters runs boat trips from Blacksod Pier in County Mayo. The business is run by the Lavelle family, who are from Inishkea, and it says the family has carried people and cargo to the Inishkea Islands since 1851.
Its trips include an Inishkea Island tour, which it calls its most popular, an Inishkea walking tour, an Inishkea ferry, a wildlife sea safari, sea angling, an Achill Island ferry, and private hire for groups.
Its guide to Blacksod points to the ancient monastic ruins and the remains of coastal communities on Inishkea. It also describes Blacksod Lighthouse, which has stood over Blacksod Bay since 1866 and gave the weather forecast behind the 1944 D-Day landings, and the ruins of St Derbhile's Church and Holy Well at Falmore.
The business says its sea safaris fill up fast in July and August.
