About Kakaban Lake

Kakaban Lake is a lake located in the middle of Kakaban Island, part of the Derawan Islands area, Berau Regency, East Kalimantan. Surrounded by forest and natural vegetation, this lake offers an atmosphere that feels different from typical beach or island destinations. Its location inside the island also makes the journey to Kakaban Lake an experience of its own for travelers.

The name “Kakaban” comes from a local language meaning “to embrace,” referring to the shape of Kakaban Island that seems to wrap around the lake area. This lake is one of the main attractions of Kakaban Island and is often visited as part of a broader Derawan Islands exploration trip. When you visit, you can enjoy the calm atmosphere of the lake surrounded by natural greenery.

What Makes Kakaban Lake So Unique?

The main uniqueness of Kakaban Lake lies in the presence of stingless jellyfish living inside the lake. You can swim or snorkel while observing these jellyfish up close in their natural habitat. This experience makes the jellyfish lake at Kakaban different from other snorkeling spots that usually offer coral reefs and marine fish.

Besides being a jellyfish habitat, Kakaban Lake has an ecosystem that developed under relatively isolated conditions from the open sea. This condition has caused several organisms inside the lake to undergo a different adaptation process compared to their relatives living in the ocean. Because of its ecological uniqueness, Kakaban Lake is not only appealing as a tourist destination but also holds important value for research and conservation.

The History Behind Kakaban Lake’s Formation

Kakaban Lake was formed through a geological process that took place over an extremely long period of time. In the past, this area was part of a marine environment before geological changes formed land surrounding part of its waters. Over time, seawater in the area became trapped, forming a body of water separated from the open sea.

After being isolated, the seawater inside the lake mixed with rainwater and groundwater, forming a distinctive water condition. This environmental change occurred gradually and influenced the adaptation process of the organisms living within it. This is the very process that shaped the unique ecosystem of Kakaban Lake that you can still see today.

Location of Kakaban Lake

Kakaban Lake is located on Kakaban Island, part of the Derawan Islands area, Berau Regency, East Kalimantan. Administratively, Kakaban Island falls within Payung-Payung Village and is part of a coastal and small islands conservation area. Because of this, tourism activities on the island need to follow the regulations set in place to protect the lake’s ecosystem and its surrounding environment.

Kakaban Island is located within Maratua District and is known as one of the main destinations frequently visited while exploring the islands in this region. Besides Kakaban Lake, the Derawan Islands area also includes popular destinations such as Derawan Island, Maratua Island, and Sangalaki Island.

How to Get to Kakaban Lake

Getting to Kakaban Lake begins with a trip to Berau Regency, East Kalimantan, followed by a combination of overland and sea travel. The route used may vary depending on your departure point, accommodation location, and chosen itinerary. However, in general, the journey to Kakaban Lake follows these stages:

1. Flying to Kalimarau Airport
   Air travel to Kakaban Lake usually starts with a flight to Kalimarau Airport (BEJ) in Berau. If departing from a city without a direct flight, you may need to transit first before arriving in Berau. After landing, the journey continues by vehicle toward the departure harbor.
2. Continuing Overland to Tanjung Batu Harbor
   From Kalimarau Airport, you need to travel overland to Tanjung Batu Harbor, which serves as the main departure point toward the Derawan Islands, including Kakaban Island. The travel duration depends on traffic conditions and the chosen route. It is best to allow enough time so the journey to the harbor goes smoothly.
3. Crossing to Kakaban Island by Speedboat
   After arriving at Tanjung Batu Harbor, the journey continues by speedboat toward Kakaban Island. In many travel itineraries, the sea crossing to Kakaban is often combined with visits to other islands or attractions within the Derawan Islands. The crossing duration can vary depending on the departure point as well as weather and wave conditions during the trip.
4. Walking from the Jetty to the Lake
   Once you arrive at Kakaban Island, you will disembark at the jetty and continue along a designated path toward the lake area. This path passes through the green areas of Kakaban Island before bringing you to the entrance point of Kakaban Lake. Wear comfortable footwear and bring only necessary items so the walk to the lake feels more practical.

Things to Do at Kakaban Lake

The main activity at Kakaban Lake centers around observing stingless jellyfish in their natural habitat. Even so, you can also enjoy the atmosphere of the lake and the Kakaban Island area through several activities that still follow conservation rules. Here are the activities you can do when visiting Kakaban Lake:

• Swimming with Stingless Jellyfish
  Swimming with stingless jellyfish is the main experience that sets Kakaban Lake apart from other tourist destinations. You can enter the permitted area of the lake and observe the jellyfish moving slowly around you without touching or disturbing them.
• Snorkeling to Observe the Jellyfish
  Snorkeling allows you to see the shape, color, and movement of the jellyfish more clearly from the water’s surface. When using a snorkel mask, keep your movements gentle and avoid kicking too hard near groups of jellyfish.
• Observing the Lake’s Ecosystem
  Kakaban Lake is not only home to jellyfish but also has an ecosystem that developed under conditions different from the open sea. You can observe the water conditions and the life within it while learning about the unique ecosystem formed through natural processes over an extremely long period of time.
• Enjoying the Walk Across Kakaban Island
  Before reaching the lake, you will walk from the jetty along a path that passes through the green areas of Kakaban Island. This short walk gives you the chance to enjoy the island’s natural atmosphere before starting your activities at the lake.
• Taking Photos and Videos
  Kakaban Lake offers the opportunity to capture the scenery and the experience of being among the jellyfish through photos or videos. If using an underwater camera, make sure you do not chase, touch, or point the camera too closely at the jellyfish just to get a shot.

Types of Jellyfish Found in Kakaban Lake

Kakaban Lake is home to four types of jellyfish, each with different shapes, characteristics, and ways of living. All four types are known not to sting humans, allowing you to swim and observe them up close in their natural habitat. However, jellyfish should still never be touched, as their bodies are fragile and direct contact can disturb their condition.

Here are the four types of jellyfish found in Kakaban Lake:

1. Moon Jellyfish (Aurelia sp.)
   Moon jellyfish have transparent or semi-white bodies that appear gentle as they move through the water. This type feeds by catching plankton and other small organisms found in the water. Because their bodies tend to be see-through, moon jellyfish can sometimes be difficult to spot, especially in areas with strong light reflection.
2. Box Jellyfish (Tripedalia cystophora)
   Box jellyfish are small in size, with a cube-shaped bell and three tentacles at each corner of their body. This type has four sets of complex eyes that help it recognize its surroundings and navigate among underwater vegetation. This ability gives box jellyfish a more developed visual system compared to many other jellyfish species.
3. Golden Jellyfish (Mastigias cf. papua)
   Golden jellyfish have a yellowish to brownish color that makes them fairly easy to recognize in the water. This type can form groups and moves following the sun’s position throughout the day to support the microscopic algae living symbiotically within its body. This relationship allows the algae to receive sunlight for photosynthesis while also helping to provide energy for the jellyfish.
4. Upside-Down Jellyfish (Cassiopea cf. ornata)
   Upside-down jellyfish are usually found in an inverted position on the lake floor, with their arms facing upward. This position helps the microscopic algae living symbiotically within their tissue receive sunlight. Through photosynthesis, these algae produce nutrients that also help support the jellyfish’s energy needs.

These four types of jellyfish are an important part of the Kakaban Lake ecosystem and make the swimming experience here feel truly different. While inside the lake, you can observe their shapes and behavior up close without touching, chasing, or moving them. By following the rules in place and keeping a respectful distance, you help protect the natural habitat of the jellyfish at Kakaban Lake.

The Best Time to Visit Kakaban Lake

The best time to visit Kakaban Lake is generally when the weather is clear and the sea is relatively calm, since the journey to Kakaban Island is made by speedboat. These conditions can make the crossing more comfortable while also helping maintain good visibility underwater. For trips to the Derawan Islands, the period between April and October is often preferred because the weather tends to be drier compared to other months.

That said, weather and wave conditions can change, so you still need to check the forecast before departing. If Kakaban Lake is included in an island-hopping itinerary, the visiting schedule can also be adjusted based on sea conditions on the day of travel. Beyond choosing the right time of year, arriving on a clear day can help you enjoy swimming and observing the jellyfish more comfortably.
