If you’re looking for things to do in St Ives, a boat trip to Seal Island is an unmissable experience. Just three miles off the St Ives coast, this rocky outcrop is home to a colony of Atlantic grey seals, making it one of the best wildlife-watching spots in Cornwall.
What is Seal Island?
Seal Island is the largest of a small group of rocky islets known as The Carracks, located just off the coast between St Ives and Zennor. The name comes from the Cornish word for ‘rocks’ (kerrek), but these days it’s the playful grey seals that steal the show. You’ll often spot them basking on the rocks, bobbing in the waves, or curiously watching boats as they pass by.
