St. Lucia is a rainforest island as much as a beach one. You'll want hiking shoes for the Pitons, an old swimsuit for the Sulphur Springs mud baths, and rain gear, because even the dry season sees regular showers.

What shoes should you pack for St. Lucia?
Hiking shoes with real grip, plus sandals. Gros Piton is a steep, rocky climb that is often muddy, and rainforest trails stay slick. Bring water shoes for rocky beaches and boat landings.
What do people wear in St. Lucia?
Resort casual. Cover up over swimwear away from the beach, including in Castries and Soufrière. Nicer resort dinners expect smart-casual clothes. Don't wear camouflage: clothing in a camouflage pattern is restricted by law in St. Lucia, including for visitors and children.
What to pack for hiking the Pitons?
Grippy shoes, at least two liters of water, sunscreen and a light rain layer. Gros Piton is steep and humid, and guides are required, so book ahead. Start early to beat the heat.
What to wear at the Sulphur Springs?
An old dark swimsuit. The volcanic mud and sulfur water can stain fabric and leave a smell. Bring a towel and a plastic bag for the wet suit.
What plugs does St. Lucia use?
St. Lucia uses Type G sockets at 240V, the same as the UK. US, Canadian and EU visitors need an adapter. Most phone and laptop chargers handle 240V, but check hair tools before you plug in.
