Stop at this exciting area in St. Lucia Island and discover why it is known as the Caribbean’s only drive-in volcano.

Sulphur Springs is the most active geothermal area in the whole Lesser Antilles, a group of islands in the Caribbean Sea. It is part of Soufrière, a town located within the caldera of the dormant Qualibou volcano. Explore this famous attraction and enjoy the thrill of driving through a hot volcanic crater.

The word geothermal comes from the Greek “thermos,” which means hot. That is exactly what you are going to find in Sulphur Springs. The temperature below the Earth's crust is so high that it melts the rocks and heats the water in the surface. The water can become so hot that it boils and rises as steam. See bubbling mud pools, hot springs and fumaroles (steam vents) surrounded by huge clay-rich rocks. Temperatures of up to 342 F (172 C) have been recorded in the fumaroles.

While you are in Sulphur Springs, be sure to enjoy a healthy mineral bath. The name of Soufrière comes from the French word “soufre,” which means sulfur. It is not surprising that this well-known spot has puddles and hot springs bubbling with sulfur-laden steam. Bathe in the warm sulfuric pools located just outside the springs and experience its famous soothing effects on your body.

Visit Sulphur Springs and see the value it could have as a potential source of power for humankind. Geothermal energy is cost effective, sustainable, reliable and environmentally friendly. There have been numerous studies to investigate the big energy potential of Sulphur Springs.

Sulphur Springs is about a 10-minute drive from Soufrière’s town center. Rent a car from the many car rental agencies on the island. Remember that to do so, you need an international driving license or a temporary St. Lucia license. Buy a temporary one at the car rental agency, the airport immigration department or a police station. The roads in the area are usually steep, winding and narrow, so if you prefer not to drive, catch a local bus or take a taxi.
