St. Lucia's landmarks are the two volcanic spires, so-called pitons, rising high over the town Soufriere on the west coast. The smallest, Petit Piton, is is 743 m (2,438 ft) high while the tallest, Gros Piton is 771 m (2,530 ft) high. Both peaks can be hiked and/or climbed. Gros Piton is the most doable and can be done in 4-6 hours return and is not too difficult. A guide is required and hired at the park center. Scaling Petit Piton is a different story as it's steep with some challenging sections with fixed ropes. The pitons are UNESCO World Heritage site and depicted on St. Lucia's flag and national beer.
