Guadeloupe's Natural Sanctuary. Explore 22 attractions across the island.
Petite Terre is a day trip, not a destination for overnight stays, and that constraint actually concentrates the experience into something memorable. The two uninhabited islets - Terre de Bas and the smaller Terre de Haut - are a national nature reserve with a strict daily cap of 200 visitors, meaning the beaches and reefs never feel overrun. Most boats depart from Saint-François on Grande-Terre at around 8 AM, and the crossing takes 60 to 90 minutes depending on sea conditions and the type of vessel. Choose your operator carefully: some run large motorized catamarans that pack in 40 to 50 people, while others offer smaller boats with groups of 12 to 15 that feel more like an expedition than a tour.
On arrival at Terre de Bas, you land on the northern beach - a sweep of white sand and turquoise water that looks computer-generated but is entirely real. Within minutes of stepping ashore, you will encounter the Petite Terre iguana (Iguana delicatissima), the island's most famous resident. An estimated 10,000 of these Lesser Antillean iguanas live on the islets, and they are remarkably habituated to humans, basking on the sand and trails without much concern for visitors. Do not feed or touch them - rangers enforce the rules and fines are real.
The snorkeling here is exceptional. The marine reserve surrounding the islands extends 200 meters from shore, and the protected reefs are thick with sea fans, brain coral, and parrotfish. Sea turtles are regular sightings, and nurse sharks cruise the shallows near the mangrove edges.
The 1840 lighthouse on Terre de Bas is worth the short walk from the beach - it is no longer operational, but the view from the surrounding area takes in the full sweep of both islets and the open Atlantic beyond. Rangers give brief ecological talks near the lighthouse most mornings, explaining the reserve's conservation efforts and the threats facing the iguanas from habitat loss on other islands.
Bring polarized sunglasses for the water, reef shoes for the rocky patches near the lighthouse trail, and a waterproof bag for your phone.
The protected waters around Petite Terre offer some of the best snorkeling in all of Guadeloupe. Visibility regularly exceeds 30 meters, and the healthy reef supports sea fans, elkhorn coral, parrotfish, trumpetfish, and sergeant majors. Sea turtles are common, and nurse sharks are occasionally spotted in the shallows. Most operators provide masks and fins.
Petite Terre hosts one of the largest remaining populations of Iguana delicatissima, with an estimated 10,000 individuals. They bask on the beaches and trails and are remarkably calm around humans. This is one of the few places in the Caribbean where you can observe these endangered reptiles in their natural habitat without disturbance.
A short trail from the main beach leads to the historic lighthouse on Terre de Bas. Built in 1840, it is no longer operational but offers an elevated vantage point over both islets and the surrounding sea. Rangers often give ecological briefings in the lighthouse area, explaining the reserve's conservation work.
The main landing beach on Terre de Bas is a pristine crescent of white sand with shallow, calm turquoise water. With only 200 visitors allowed per day, it never feels crowded. The water is warm and clear year-round, and the lack of motorized water sports keeps the atmosphere serene.
Green sea turtles and hawksbill turtles frequent the waters around Petite Terre, grazing on sea grass beds near the shore. Early morning snorkelers have the best chance of extended encounters before the turtles move to deeper water. Keep a respectful distance and avoid chasing them.
Some tour operators bring kayaks or stand-up paddleboards, allowing you to explore the coastline beyond the main snorkeling area. The channel between Terre de Bas and Terre de Haut is shallow and sheltered, and paddling along the mangrove edges reveals juvenile fish and small rays.

A shallow turquoise lagoon between the two islets of Petite Terre, renowned for its crystal-clear waters and abundant marine life. Snorkeling here reveals sea turtles, rays, nurse sharks, and colorful reef fish in a protected natural reserve.

A 19th-century lighthouse on Terre-de-Bas, now housing a small museum about the reserve's ecosystem. The surrounding area is home to one of the largest populations of the endangered Lesser Antillean iguana.

A strictly protected nature reserve covering both islets, home to over 10,000 Lesser Antillean iguanas - the largest colony in the world. The reserve also protects nesting sea turtles, hermit crabs, and rare coastal vegetation.

A pristine white-sand beach on the northern shore of Terre-de-Haut, accessible only by boat. The untouched setting, lack of development, and warm shallow waters make it one of the most exclusive beach experiences in the archipelago.
