Off Le Robert, on Martinique’s Atlantic coast, a small slip of land concentrates everything that makes the island so wildly charming: a turquoise lagoon sheltered by the coral reef, colonial ruins reclaimed by vegetation, and above all a colony of iguanas you won’t encounter anywhere else in France. Îlet Chancel is the largest of the eight islets in the Bay of Le Robert, and one of the excursions I most often recommend to the travellers we host. Here is everything you need to know to plan your outing, with respect for a protected and fragile species.
Where Îlet Chancel is and why you should go
Îlet Chancel lies within the municipality of Le Robert, on the Atlantic side, about a 30-minute drive from Fort-de-France (the capital) and 45 minutes from Aimé Césaire airport in Le Lamentin. At roughly 70 hectares, it is by far the largest islet in the bay, set in the heart of a lagoon protected by the coral reef. This setting creates calm, shallow, crystal-clear waters that are perfect for kayaking and swimming.
What makes Chancel unique is its dual identity:
- Natural: it shelters Martinique’s main population of Lesser Antillean iguanas (Iguana delicatissima), an endangered endemic species.
- Heritage: you can explore the remains of an 18th-century sugar mill and a distinctive brick tower, both witnesses to the island’s colonial past.
For travellers staying in the South (Sainte-Anne, Le Diamant, Les Trois-Îlets), Chancel offers a valuable contrast with the white-sand beaches of Les Salines: here you’re in Atlantic Martinique, more secret and greener.
The Lesser Antillean iguana: a species to protect
The islet’s main draw is its iguanas. But take care not to confuse them: this is the Lesser Antillean iguana (Iguana delicatissima), recognisable by its grey-green coat and the absence of stripes on its tail, unlike the common iguana (Iguana iguana), which threatens it through hybridisation.
Why this species is endangered
Iguana delicatissima is classified as endangered on the IUCN Red List. Martinique is home to one of the last viable populations, and Îlet Chancel is a major refuge for it. Several threats weigh on the species:
- Hybridisation with the common iguana, an introduced and invasive species.
- Predation by rats, cats and other introduced animals.
- Habitat loss and human disturbance.
That is why your behaviour on site genuinely matters. You’re not in a zoo: you’re a guest in the home of a fragile species.
The rules of good conduct to follow
On my outings, I systematically remind everyone of these simple but essential guidelines:
- Never feed the iguanas. Bread, fruit or chips disrupt their diet and create a dangerous dependency.
- Keep your distance: observe without touching, and stay at least a few metres away.
- Leave nothing behind: take away all your waste, including food peelings.
- Stay on marked trails to avoid trampling the nesting areas.
- Hold on to children and avoid sudden movements: a stressed iguana may bite or flee toward risky areas.
These actions aren’t mere recommendations: they directly contribute to the colony’s survival.
How to organise your trip to Îlet Chancel
The islet is only accessible by sea, from the village of Le Robert. You have two main options.
By kayak (the option I prefer)
The kayak crossing from Pointe Savane (Le Robert) to the islet takes about 20 to 30 minutes depending on your pace and the wind. Since the lagoon waters are sheltered, it’s accessible to beginners in good physical condition. Several rental operators offer guided outings.
- Indicative price: €25 to €40 per person for a guided half-day.
- Total duration: 2.5 to 3 hours, including the visit to the islet.
- What to bring: water, closed shoes for walking, a waterproof bag.
The advantage of the kayak: the silent approach, the gentle effort and gliding over the clear seabed where you sometimes spot rays and fish.
By boat or shuttle
For those who’d rather not paddle, shuttles and glass-bottom boat trips serve the islet, often combined with a stop at the famous fonds blancs of the Bay of Le Robert (sandbanks where the water comes up to your waist right in the middle of the sea).
- Indicative price: €35 to €55 per person depending on the package.
- Common combo: Îlet Chancel + swim at the fonds blancs + a creole aperitif on some outings.
On site: ruins and trail
Once you’ve landed, allow 1 to 1.5 hours to walk around the islet. A trail leads to the sugar-mill ruins and the tower, from which the view over the bay is superb. This is also where encounters with iguanas are most frequent, as they perch on the sun-warmed low walls.
