Seal island is a name given to the largest of the rocky islands known as the Carracks, just off shore about a mile and a half round the coast from Porthzennor Cove in the direction of St Ives.
Seal island is so named because it is home to a colony of grey seals (halichoerus grypus), while the name Carracks derives from the Cornish word Kerrek, simply meaning rocks.
Boat trips are available from St Ives to visit Seal Island, and if you’re a fan of Seals, the Cornish Seal Sanctuary in Gweek is also worth a visit.
