Marianne Island
Island Uninhabited Seychelles islet with snorkeling and reef
A small islet in the Seychelles reached by boat from Mahé, popular for day‑trip snorkeling, seabird observation and short beach outings.
Marianne Island is a small island in the Seychelles archipelago. It is uninhabited and part of the island nation’s offshore island groupings.
The island is used as a habitat for seabirds and coastal flora and may be visited for wildlife observation and coastal scenery when visits are permitted. It is not a populated or developed tourist destination.
Marianne Island has no permanent settlement and has remained largely natural in character; it has been mentioned in charts and records of the Seychelles but does not have a recorded history of major construction or long-term habitation.
Situated in the Seychelles island chain in the Indian Ocean, the island lies among the outer islands of the republic and is accessible only by private boat from the main islands.
How to Get to Marianne Island #
Marianne Island is reachable by private boat or day‑trip charter from Mahé or Praslin; many excursions that include the Sainte Anne Marine Park also stop at smaller islets. Arrange landings through licensed operators and check marine park rules.
Tips for Visiting Marianne Island #
- Day visitors should arrive on early boats to maximise time on the island-landing slots are limited.
- Respect nesting bird colonies and obey any local conservation signage-many islets here are important bird habitats.
- Bring snorkeling gear if tides and boat operators permit; clear water and granite formations make for pleasant exploration.
