St Lucia

The west coast dive sites of St Lucia stretch from Anse Chastanet in the south to Pigeon Island in the north, offering vibrant reefs and dramatic wall dives beneath the majestic peaks of the Pitons.

Part of the Windward Islands of the Lesser Antilles, St Lucia is a volcanic island in the Caribbean Sea, renowned for its dramatic scenery and lush tropical island landscapes. The island was originally named "Louanalao" by the indigenous Arawak people, meaning "Land of the Iguanas", a name that hints at the rich wildlife found here. 

Its strategic location and numerous sheltered bays later made it a favoured haven for pirates during the Age of Sail. Today, this captivating Caribbean destination stands as a vibrant melting pot of African, French, and British heritage. This rich history is reflected in everyday island life—English is widely spoken as the official language, though a French-based Creole echoes through the markets and coastal villages. Visitors are charmed by a distinctive culture and wonderfully relaxed atmosphere, blending traditions of the indigenous Carib people with centuries of European influence, all set against a striking volcanic island backdrop. 

With its resorts, well-equipped dive centres, and an array of dive sites, St Lucia caters superbly to all types of traveller, from couples seeking a picturesque retreat, to families in search of an active break. Solo travellers and experienced divers alike will find a welcoming community, professional diving instructors, and fantastic opportunities for a scuba diving adventure.
