Curieuse Island Giant Tortoise Sanctuary and Trails

Curieuse Island sits two kilometers off the northern coast of Praslin and functions as a strictly protected national park requiring a 300 SCR entry fee for all non-residents. This 2.86-square-kilometer landmass remains famous for its free-roaming population of more than 300 Aldabra giant tortoises and its status as a primary sanctuary for the endemic Coco de Mer palm. Visitors typically arrive via taxi boat from Anse Volbert, landing at Baie Laraie where the ranger station manages conservation fees and ecological monitoring. Unlike the larger granitic islands, the red earth here contrasts sharply with the white coral sands, giving the island its original French name, Ile Rouge.

The Giant Tortoise Colony and Baie Laraie

Conservation Efforts for the Aldabra Species

The primary attraction at Baie Laraie is the tortoise sanctuary, which has successfully reintroduced hundreds of Aldabra giant tortoises that were once nearly extinct on the inner islands. These reptiles can live for over 100 years and weigh up to 250 kilograms. While they are accustomed to human presence, the rangers enforce strict rules against sitting on the animals or feeding them non-native vegetation. Most tourists cluster around the main feeding area near the shore, but a short walk inland usually reveals older, larger males resting in the shade of the takamaka trees away from the noise.

The Tortoise Rearing Station

Young tortoises remain in a protected nursery enclosure until they reach five years of age or a size sufficient to protect them from natural predators like large crabs. This management strategy ensures the survival rate of hatchlings is significantly higher than in the wild. You can see the different age cohorts separated by size, providing a clear visual of their growth stages. It is a detail often missed, but the rangers keep meticulous records of each individual shell marking, which helps them track the health of the entire 300-strong population across the island.

Hiking the Mangrove Boardwalk to Anse St. Jose

Navigation of the Coastal Trail

A 1.5-kilometer trail connects the two main bays of the island, winding through a diverse topography that transitions from coastal scrub to dense mangrove forests. The path involves climbing over several granite ridges—some reaching an elevation of nearly 100 meters—which offer clear views across the Curieuse Marine National Park toward Praslin. The humidity trapped within the valley can make the trek feel more strenuous than the distance suggests. Bringing at least one liter of water per person is necessary since the island has no commercial shops or kiosks to purchase supplies.

Identifying the Native Mangrove Species

The boardwalk section of the trail crosses one of the largest mangrove swamps in the Seychelles, home to six distinct species of mangroves. You can distinguish the Great Mangrove by its large, buttressed roots, while the Red Mangrove is identifiable by its characteristic prop roots that arch into the water. This ecosystem serves as a vital nursery for lemon sharks and various species of rays that are often visible in the shallow channels during high tide. Observation from the wooden platforms is much more effective during the rising tide when marine life enters the submerged root systems for protection.

Historical Heritage and the Doctors House

Architecture of the Former Leprosarium

At the southern end of the trail in Anse St. Jose stands the Doctor's House, a well-preserved example of French colonial Creole architecture built in 1873. The building served the resident physician of the leper colony that operated on the island from 1829 until 1965. Today, the ground floor serves as a museum displaying information about the island's history and the biology of the local fauna. The thick coral-rag walls and wide verandas were designed to facilitate airflow—a practical necessity in the tropical climate—and offer a quiet respite from the midday sun.

Rare Flora and the Turtle Cemetery

The area surrounding the Doctor's House contains several Coco de Mer palms growing naturally on the hillsides. While the Vallee de Mai on Praslin is more famous, seeing these palms here feels more authentic as they compete for space with other native trees like the Bois Mapou. Near the ruins of the old patient quarters, a small path leads to a series of unmarked graves often called the turtle cemetery, though it actually contains historical remains from the colony era. This part of the island sees fewer visitors than the tortoise sanctuary, making it a better spot for those seeking a quiet environment to photograph the granite rock formations.

Frequently Asked Questions

How much does it cost to visit Curieuse Island?

Non-residents must pay an entry fee of 300 SCR per person to the Seychelles National Parks Authority. This fee is usually paid by credit or debit card at the ranger station in Baie Laraie or included in the price of a commercial tour package.

Are there any restaurants or shops on the island?

No commercial facilities exist on Curieuse, so you must bring all food, water, and sunscreen with you. Most visitors arrange a boat excursion that includes a Creole barbecue lunch prepared on the beach by the tour operators at designated picnic sites.

What is the best time of day to see the tortoises?

Arriving before 10:00 AM allows you to see the tortoises while they are most active before the midday heat forces them into the shade. Early arrival also helps you avoid the large tour groups that typically arrive from Praslin and La Digue around noon for lunch.

Is the hiking trail suitable for young children?

The 1.5-kilometer trail is manageable for children who are accustomed to walking, but it does involve steep granite steps and uneven boardwalks. Sturdy footwear is recommended as the red soil becomes very slippery after the frequent tropical rain showers.
