At Grandes Cayes beach rises to the top of the list when you think of the wild, authentic beauty of Saint-Martin. This coastline, protected by the National Nature Reserve, offers a setting where nature reigns supreme, far from the crowds and hustle and bustle. Over the years, Grandes Cayes beach has preserved its identity: once a place where families gathered for Sunday barbecues, today a preserved area where white sand stretches as far as the eye can see, under the peaceful gaze of the island of Tintamarre.
Exceptional ecological wealth
A site classified as a National Nature Reserve
It takes more than just a glance to grasp the biodiversity of Grandes Cayes beach. The majority of the site is fully protected. Every season, sea turtles choose this beach to lay their eggs, preserving a precious natural cycle. The coastal vegetation, dominated by majestic cacti and other xerophilous species, shapes a landscape typical of northern Saint-Martin, at the foot of the Red Rock massif.
Remarkable flora and fauna
The terrain surrounding Grandes Cayes beach is home to red gum trees, mapous, pear trees and the rare guaiac tree, all protected by the reserve’s strict regulations. Careful walkers may also spot rare orchids or striped iguanas, an invasive species that has replaced the Lesser Antillean iguana. The area is also home to endemic lizards, such as anolis, skinks and geckos, veritable guardians of this ecological heritage.
Landscapes shaped by sea and rock
A spectacular waterfront
Atlantic rollers lick the northeast-facing of Grandes Cayes beach, but the coral reef protects the bay and Pinel islet from the most powerful assaults. This reef, enclosing a narrow channel, provides shelter for seagrass beds. At depths of between three and seven meters, rays, turtles and sharks frequently come across it: this sanctuary serves as a nursery for a number of aquatic species, as Julien Chalifour, deputy director of the Nature Reserve, explains.
Two trails to immerse yourself in nature
The site is not just a destination for contemplation; it also invites discovery on foot. To the north, the sentier des Froussards guides walkers to Anse Marcel, winding through lush vegetation. To the south, another trail follows the hill along the coastline, offering breathtaking views of îlet Pinel and the sea below.
An authentic place, far removed from tourist development
Absolute serenity and simplicity
The Grandes Cayes beach offers a rare experience in the Caribbean: no facilities, no services, just peace and space to reconnect with the essential. It’s advisable to bring your own food and water, as nature reclaims its rights. The place exudes peace, and you hardly come across other walkers: ideal for those seeking tranquillity away from conventional beaches.
A heritage to protect
Grandes Cayes beach, with its rich biodiversity, is the subject of a restoration project designed to enhance its protection. The project, which is currently underway, reflects the company’s ongoing commitment to the sustainable management of the site, so that everyone, whether expert naturalist or curious visitor, can find something to marvel at and learn from.

Far from clichés, this unspoilt spot gives the impression of being at the end of the world, where nature reveals itself without artifice. Whether you’re an ecology enthusiast or simply looking for a soothing interlude, all you have to do is let yourself be carried away by the magic of this unique area.
