Experience Sea Turtles Conservation in Sangalaki Island

Monday, 28 Oct 2024
Sangalaki Island, a small but vibrant part of the Derawan Archipelago in East Kalimantan, Indonesia, is a treasure trove for nature enthusiasts and eco-tourists alike. Covering only 15.9 hectares, this uninhabited island offers a unique blend of pristine beaches, crystal-clear waters, and, most notably, a significant sea turtle conservation initiative. The island’s commitment to preserving its marine life, particularly sea turtles, makes it a must-visit destination for anyone interested in marine biology, conservation, or simply experiencing one of nature’s most magical phenomena.

Sangalaki Island, A Natural Sanctuary

Sangalaki Island is not just a spot on the map it's a haven of biodiversity. The island's terrain is a mix of soft, sandy beaches and coral-fragment shores, surrounded by a lagoon teeming with sea grasses and vibrant corals. The island’s surrounding waters are famous for their exceptional visibility, making it a diver's paradise. However, beyond the breathtaking underwater landscapes and thriving marine ecosystems, Sangalaki stands out for its role in sea turtle conservation.

The island’s atmosphere is tranquil, almost otherworldly, with only a few guard posts and minimal human habitation. This lack of development has allowed the natural environment to thrive, providing an ideal setting for the many species of sea turtles that come to its shores to nest. The serene ambiance of Sangalaki Island is one of its greatest assets, allowing visitors to truly disconnect and immerse themselves in the natural world.

Sea Turtle Conservation, A Vital Mission

Sangalaki Island is a critical nesting ground for several endangered species of sea turtles, including the green sea turtle (Chelonia mydas) and the hawksbill turtle (Eretmochelys imbricata). These turtles, which spend most of their lives in the open ocean, return to the island to lay their eggs, a process that has been occurring for millions of years.

Visitors to Sangalaki have the rare opportunity to witness this ancient ritual firsthand. The peak nesting season, typically from July to September, is the best time to visit if you wish to observe the turtles coming ashore to lay their eggs. The experience of watching these magnificent creatures laboriously dig nests in the sand lay their eggs, and then slowly return to the sea under the cover of night is both humbling and inspiring.


The conservation efforts on Sangalaki are extensive. The islands conservation team works tirelessly to protect the turtle nests from predators and human interference. They carefully monitor the nests, ensuring that the eggs are safe until they hatch. When the time comes, visitors can participate in the release of the hatchlings, guiding them to the sea moment that is both joyous and poignant, as these tiny creatures begin their perilous journey into the ocean.

Educational Opportunities and Responsible Tourism

One of the highlights of visiting Sangalaki Island is the educational aspect of the conservation program. The local conservation team offers guided tours and educational sessions where visitors can learn about the life cycle of sea turtles, the challenges they face due to habitat loss, climate change, and human activities, and the efforts being made to ensure their survival.

Responsible tourism is at the heart of the Sangalaki experience. Visitors are encouraged to respect the natural environment, avoid disturbing the turtles, and adhere to guidelines set by the conservation team. The emphasis is on minimizing human impact while maximizing the educational and conservation value of the visit. This approach not only helps protect the turtles but also enhances the overall experience, making it more meaningful and impactful.

Getting There and Where to Stay

Reaching Sangalaki Island involves a journey that combines air travel and boat rides, making it a true adventure before you even set foot on the island. The most common route is to fly into either Balikpapan or Berau in East Kalimantan. From Berau, you’ll need to travel by road to Tanjung Batu Port, where you can catch a boat to Derawan Island. The final leg of the journey is a boat ride to Sangalaki, which, although time-consuming, is well worth the effort for the pristine beauty that awaits.

When it comes to accommodation, while Sangalaki itself has limited options, staying on nearby islands such as Derawan or Maratua is a popular choice. If you’re particularly interested in sea turtle conservation and want a luxurious yet eco-friendly stay, Sienna Resort Maratua is highly recommended.
