Kakaban Island in East Kalimantan captivates with its unique & hidden lake full of non-stinging jellyfish, the beauty of its tropical forests, and its amazing diving experiences.
Kakaban Island, part of the Derawan Islands in East Kalimantan, is a stunning destination with its uniqueness and natural beauty.
The island is characterized by a brackish water lake that is home to thousands of stingless jellyfish, providing a travel experience that is hard to find anywhere else.
n addition, the history of the island’s formation, estimated to have occurred around 12 million years ago, adds to its fascinating geological and ecological appeal. Here is a complete review of the attractions, activities, and how to get to Kakaban Island.
Geological History of Kakaban Island
Kakaban Island was formed through a natural process that occurred over millions of years. The shifting of the Mangkalihat Peninsula (Berau, Indonesia) and the Simpurna Peninsula (Sabah, Malaysia) caused coral deposits to be lifted from the seabed.
According to research by Oxford University in the book The Ecology of the Indonesian Seas (1994), this process took up to 2 million years.
The island has a shape resembling the number 9 when viewed from above, with a large depression in the middle known as a lagoon.
The lagoon is isolated from the sea, and its water gradually turns brackish as it mixes with rainwater, creating a unique ecosystem. This phenomenon makes Kakaban Island different from other islands in the Derawan Islands.
The Attractions of Kakaban Island
1. Habitat of Non-Stinging Jellyfish
One of the main attractions of Kakaban Island is Kakaban Lake which is home to thousands of non-stinging jellyfish.
The existence of these jellyfish is the result of thousands of years of adaptation in a closed environment without natural predators. Tourists can swim with these jellyfish, providing a very unique and enjoyable experience.
However, there are several rules that must be followed to maintain the ecosystem and welfare of jellyfish, such as not using sunblock, not bringing swimming aids such as fins, and not lifting jellyfish out of the water.
2. Lush Tropical Forests and Mangroves
To reach Lake Kakaban, tourists must pass through dense tropical forests with various types of typical flora such as Bakung, Asing-asing, and Ligayan trees.
In addition, there are mangrove forests around the island which add to the natural beauty and maintain the balance of the coastal ecosystem.
3. Typical Island Cuisine
It would not be complete if you visit Kakaban Island without trying its local cuisine. One of the unique foods is tehe-tehe, sticky rice cooked with coconut milk and wrapped in a sea urchin shell. It tastes similar to ketupat but with the distinctive aroma of pandan leaves.
In addition, there are kima-kima, processed sea shells cooked like dried salted fish, which are a tourist favorite.
