Saint Lucia - Soufrière -Sulphur Springs
The Sulphur Springs, located near the town of Soufrière (French for sulfur), are perhaps the world's only drive-in live volcano. (I have been inside two other dead volcanoes: Daimond Head in Oahu, Hawaii, and Fira, on the the Greek island of Santorini. The St. Lucia attraction is most intriguing. I recommend all visitors bring two things: a camera and a clothes pin.
