Discover Maratua Island: Indonesia’s Hidden Paradise for Adventure, Luxury, and Untouched Beauty
Nestled within the Derawan Archipelago in East Kalimantan, Indonesia, Maratua Island is a pristine tropical gem that remains one of Southeast Asia’s best-kept secrets. With its turquoise waters, vibrant coral reefs, and lush jungles, Maratua offers an unparalleled escape for travelers seeking adventure, relaxation, and a connection with nature. Whether you’re a diver, eco-tourist, or luxury seeker, here’s why Maratua Island deserves a top spot on your travel bucket list—and why it’s a must-feature destination for your next Indonesian getaway.
Why Maratua Island ?
- A Diver’s Dream Destination
Maratua is part of the Coral Triangle, the global epicenter of marine biodiversity. Its waters teem with manta rays, sea turtles, barracudas, and even whale sharks. Famous dive sites like Big Fish Country and Channel of Maratua attract underwater enthusiasts year-round. The island’s unique geography—a large atoll with dramatic drop-offs and caverns—creates thrilling drift dives and unforgettable encounters with pelagic species.
2. The Enchanting Kakaban Lake
Just a short boat ride from Maratua lies Kakaban Island, home to one of only two places on Earth where you can swim with non-stinging jellyfish. This brackish lake, formed by ancient tectonic shifts, offers a surreal experience as thousands of harmless golden and moon jellyfish glide around visitors—a bucket-list moment for nature lovers.
3. Pristine Beaches & Secluded Vibes
Unlike crowded Bali or Lombok, Maratua’s powdery white beaches and coconut palm-fringed shores remain blissfully untouched. Picture yourself unwinding on Private Sienna Resort Beach or watching fiery sunsets from a private overwater bungalow. The island’s remoteness ensures an intimate, crowd-free experience.
4. Rich Marine Conservation Efforts
Maratua is a hub for sustainable tourism. Local initiatives protect endangered sea turtles and coral reefs, offering travelers opportunities to participate in conservation activities. Eco-conscious resorts partner with marine biologists to promote responsible diving and wildlife preservation. Just a one-hour boat ride from Maratua lies Sangalaki Island, a haven dedicated to wildlife conservation, particularly for the protection and preservation of sea turtles. Sienna Resort is committed to promoting sustainable tourism through initiatives such as mangrove planting and collaborating with local communities and coral reef conservation teams to support coral reef restoration efforts.
5. Luxury Meets Wilderness
For those craving comfort amid raw nature, Maratua boasts exclusive resorts like Sienna Resort, featuring overwater villas with direct lagoon access. Enjoy fresh seafood feasts, spa treatments with ocean views, and guided island-hopping tours tailored to your interests.
