GROS & PETIT PITONS, ST. LUCIA - Together, the two peaks are part of the Pitons Management area, a UNESCO World Heritage Site since 2004. In addition to their impressive geography, the Pitons are also home to a huge variety of plant and animal life. Lush vegetation surrounds the slopes, providing habitat for hundreds of different species. Volcanic activity continues to this day, with hot springs bubbling from the rocks.
