Hike the Piton
Planning a trip to St. Lucia, the chances of the Tet Paul Nature Trail already being on your list are pretty high. If you're feeling more adventurous (and fit!), the four-hour Piton hike is the activity for you. You have the option of hiking the Gros (large) or Petit (small) Piton, but the one more travelers do is the Gros Piton.
It's a two-hour climb, taking you up 2000 feet, and a two-hour trek back down, depending on your athletic ability. This hike isn't for the weak-kneed though; the downward hike is very steep and can be really rocky and slippery. Try to start your hike on the earlier side as later in the day gets really hot and the hike can become tougher. The sweeping views while hiking are breathtaking, and while this hike is challenging, it's equally rewarding.
