Turtle Islands Cluster Guide 2026: Taganak, Baguan & the Sea Turtle Sanctuary Islands of the Sulu Sea
The Turtle Islands Cluster forms the southeastern edge of the Sulu Archipelago and consists of a small group of islands located between Tawi-Tawi and Sabah, Malaysia.

Why the Turtle Islands Are Different
Unlike Basilan, Sulu, or Tawi-Tawi, the Turtle Islands Cluster is not defined by large communities, tourism infrastructure, or island-hopping routes. Instead, the islands are valued for their environmental significance and their role in protecting marine wildlife.
The cluster forms an internationally important sanctuary where conservation efforts focus on safeguarding nesting beaches, maintaining healthy coral reef systems, and protecting critical marine habitats. For many visitors, the experience is less about sightseeing and more about understanding the importance of preserving one of the Philippines’ most valuable wildlife areas.
Geographic Overview
The Turtle Islands Cluster lies within the Sulu Sea between Tawi-Tawi and Sabah. The islands are surrounded by biologically rich waters that support coral reefs, seagrass meadows, mangrove habitats, and important feeding grounds for marine wildlife.
The remote location of the islands has helped preserve many natural habitats while also creating challenges for conservation management and visitor access.
Conservation Significance
The Turtle Islands Cluster is one of the most environmentally important island groups in the Philippines and forms part of an internationally recognized marine conservation landscape.
The islands are best known as critical nesting grounds for endangered sea turtles, particularly:
- Green Sea Turtles
- Hawksbill Sea Turtles
Protected beaches, coral reefs, and offshore habitats support the life cycles of numerous marine species and contribute significantly to biodiversity conservation efforts throughout the Sulu Sea.
Unlike many Philippine island destinations that are primarily known for tourism, the Turtle Islands are valued chiefly for:
