About Denis Island

Denis Island is a small private island in the Seychelles Inner Islands group, operated as a boutique resort with its own airstrip and basic guest facilities. The island is noted for beaches, coral reef and marine recreational opportunities.

Visitors use the island for accommodation-based holidays featuring snorkeling, diving, sport fishing and nature observation around the reef and shoreline. The island’s compact infrastructure centers on a small resort area and a short airstrip for inter-island flights.

Denis Island has been used in modern times as a private resort destination and has hosted small-scale tourism and conservation efforts; much of its economy and infrastructure are oriented to guest stays and marine recreation.

Denis Island lies among the Inner Islands of the Seychelles in the Indian Ocean, north of the main island of Mahé and accessible by short domestic flights or boat transfers.

  • Access and services: Operates as a privately run island resort with limited guest capacity and on-island services, so advance booking and transfer coordination are required.

  • Resort and airstrip: A small private resort complex and guest accommodations built on the island and an unpaved airstrip that receives scheduled charter flights.
  • Beaches and reef: Beaches fringed by coral reef and shallow lagoon areas that are used for snorkeling, diving and small-boat fishing around the island.

Getting There & Around

How to Get to Denis Island

Denis Island is a private island in the Seychelles reached from Mahé (Victoria). The usual way is a scheduled light aircraft transfer from Seychelles International Airport (Mahé) to Denis Island’s private airstrip - flight time is about 20-25 minutes. The island operator also arranges boat transfers from Mahé; these are considerably longer (typically a few hours) and must be booked in advance.

Tips for Visiting Denis Island

  • Confirm transport well in advance-Denis Island is served by scheduled light aircraft/charter flights and occasional boat transfers from Mahé, and operators often require reservations tied to your accommodation.
  • Plan water activities for early morning when seas are calm and visibility for snorkeling is best; the island is known for clear reefs and turtle sightings.
  • Ask the island resort or staff about guided nature walks and birdwatching times-many visitors focus on the beach and miss the island's nesting seabirds and endemic flora.
