Hidden off the coast of East Kalimantan, Indonesia, lies Derawan Island, an undisputed Maritime Gem hat dazzles with its pristine beaches, crystal-clear turquoise waters, and an astonishing array of exotic marine life. Part of the larger Derawan Archipelago, which includes islands like Maratua, Sangalaki, and Kakaban, this destination is a diver’s and nature lover’s paradise, offering an unparalleled glimpse into the vibrant underwater world of the Coral Triangle. Its breathtaking beauty and unique natural phenomena firmly establish it as The Maritime Gem of the region.
The primary allure of Derawan Island and its surrounding islets is the incredible marine biodiversity. Divers and snorkelers are consistently mesmerized by the kaleidoscopic coral gardens, teeming with thousands of species of fish, including colorful reef fish, barracudas, and giant trevally. The area is also famous for its large pelagic species. Visitors can often spot majestic manta rays gliding gracefully, gentle whale sharks feeding peacefully, and various species of sea turtles, including green turtles and hawksbill turtles, for which Sangalaki Island is a major nesting site. A marine biology research team from the University of Borneo in Samarinda, during a field study in February 2025, documented the health and abundance of coral reefs in the Derawan waters.
Beyond the conventional diving and snorkeling, Derawan offers unique natural wonders. Kakaban Island, for instance, is home to a rare stingless jellyfish lake, where visitors can swim harmlessly among four species of jellyfish that have evolved without stinging capabilities due to the lack of predators. This extraordinary phenomenon adds another layer of fascination to The Maritime Gem.
The islands themselves boast idyllic white-sand beaches fringed with swaying palm trees, perfect for relaxation and sunbathing. The tranquil atmosphere and stunning sunsets create a serene escape from the bustling modern world. Accommodation ranges from cozy guesthouses to more luxurious resorts, catering to various budgets.
Conservation efforts are crucial to preserving Derawan’s pristine environment. Local communities, in collaboration with government agencies and conservation organizations, work to protect the delicate marine ecosystem from over-tourism and illegal fishing practices. On April 18, 2025, the East Kalimantan Provincial Maritime Affairs and Fisheries Agency launched a new initiative to promote sustainable tourism practices in the Derawan Archipelago. Visiting Derawan Island is an immersive adventure that not only showcases The Maritime Gem of East Kalimantan but also underscores the vital importance of protecting our planet’s most precious natural wonders.
