Sangalaki Turtle Island Experience

witnessing the remarkable beauty of marine life, Sangalaki Island stands out as a premier destination in Indonesia, particularly for its turtles. Known for its conservation efforts and vibrant underwater ecosystems, this island offers a rare opportunity to observe Sangalaki turtles in their natural habitat while enjoying world-class snorkeling and diving experiences.

Getting to Sangalaki Island

Located approximately 15 kilometers from Derawan Island, Sangalaki Island is easily accessible via a Sangalaki day trip. Most trips begin from Derawan, where you can find local boats offering services to the island. The journey typically takes about 30-45 minutes, depending on the sea conditions. On our trips, Sangalaki is visited by speedboat on day 2, and the boat is included.

It’s advisable to plan your visit between April and November when the weather is most favorable. During these months, the sea is generally calm, making for a pleasant journey and ideal conditions for exploring the underwater world.

What to Expect on Sangalaki Island

Sangalaki Island is renowned not only for its breathtaking beaches but also for its commitment to turtle conservation. As you step onto the island, you’ll notice the lush greenery and tranquil environment, perfect for a day of relaxation and exploration.

  • Snorkeling: The waters surrounding Sangalaki are teeming with life. You can expect to see various species of tropical fish, vibrant corals, and, of course, the stars of the show — turtles! Snorkeling here doesn’t require extensive experience; you can find accessible spots for beginners along the sandy shores.
  • Diving: For those looking for deeper encounters, diving around Sangalaki can take you to depths of up to 30 meters, where you can witness an even greater diversity of marine life. Local dive operators offer dive packages; our Derawan trips are snorkel-based and scuba diving is not included.

Turtle Watching on Sangalaki Island

Sangalaki Island is primarily known for its turtle watching opportunities. The island is home to several species of turtles, including the hawksbill and green turtles. The best times to see these majestic creatures are from May to September, when they are most active, especially during nesting season.

During your visit, you can participate in guided turtle watching tours that educate you on Sangalaki turtle conservation. The tours typically take you to nesting sites, where you can learn about the conservation efforts in place to protect these creatures. The conservation fee, which directly supports the island’s turtle conservation programs, is covered by the entrance fees included in our trips.

Visiting the Turtle Hatchery

One of the highlights of your Sangalaki experience will be a visit to the turtle hatchery. This facility plays a crucial role in the conservation of baby turtles, providing a safe space for eggs to incubate and hatch. The hatchery operates year-round, but the best months to see baby turtles in Derawan are from July through October, when hatchlings are released into the ocean.

The hatchery staff is incredibly knowledgeable and passionate about their work, making it an engaging experience. You can often participate in the release of baby turtles, a memorable event that contributes to their survival and helps raise awareness about the importance of protecting marine ecosystems.
