Almost every couple who chooses St Lucia chooses it for the Pitons. Gros Piton and Petit Piton rise from the sea on the southwest coast, and the resorts built to face them have made that view one of the most recognisable in the Caribbean. Unlike the flat coral islands further east, St Lucia is mountainous and covered in rainforest, which gives depth and layering to images that a beach horizon cannot.
The island is also compact enough that a wedding can include genuinely different environments in one day — coastline, rainforest, and the sulphur springs and waterfalls inland around Soufrière.
