Cousin Island Seychelles

Cousin Island Seychelles

Cousin is a small granite island belonging to the archipelago of Seychelles. It has an area of 34 ha and is located at about 2 kilometers to the west of Praslin. Cousin is regarded under Seychelles law as a special reserve and is also identified as an Important Bird Area. It is administered by Nature Seychelles which is a national non-profit organization.

Cousin is mostly covered by lush vegetation while being surrounded by a long sandy beach. Every morning, the island is open to visitors excluding weekends and public holidays. However, you can only access the island by the sea from Praslin.

Thanks to its natural beauties, the island is a very frequent tourist destination. Visitors mainly come to the island to spot the endemic birds and trees which are present in Cousin.


Initially, the island was a coconut plantation. It was being plundered of its vegetation and the endemic species living there started to disappear. Among the endemic species was the Seychelles warbler which went on the verge of extinction. In 1968, when the Seychelles warbler’s population was at 26 birds, the BirdLife International bought the island. Coconut trees were removed to allow the native vegetations to flourish on Cousin Island. As the native flora regenerated, the native fauna started to recover. Later in 1975, Cousin Island was declared a special reserve.
