As your St. Lucia flight prepares to land the mighty Pitons welcome you to their beloved island. Situated in the Caribbean – north of the islands of Saint Vincent and the Grenadines, northwest of Barbados and south of Martinique – St. Lucia has become a top spot for holidaymakers all year-round. Named the “the world’s leading honeymoon destination”, travellers book flights to St. Lucia for a relaxing getaway on the volcanic island. Rainforests, volcanic mountains, and pristine beaches are all within eye sight from many of the post St. Lucia resorts.
The west coast of the island is the most developed part of St. Lucia. Castries, the capital city, is where all the large cruise ships and yachts dock. Its public market provides a great introduction to the locals and their culture. Rodney Bay, Marigot Bay and Soufriere are where the resorts are located. And the famous “drive-in” volcano, Mount Soufriere, with its sulphur springs and pools is a major attraction. Nature lovers can explore the two national parks, Fregate Islands Nature Reserve and the Maria Islands Nature Reserve and Grand Anse home to rare birds and endangered sea turtles.
