Indonesia is a diver’s paradise, known for its iconic dive destinations like Raja Ampat and Komodo. Yet, hidden away on the northern coast of Papua lies a lesser-known treasure: Cenderawasih Bay. This remote marine wonderland is a true hidden gem, offering unique underwater experiences that set it apart from other diving hotspots. With its stunning coral reefs, fascinating WWII wrecks, and the extraordinary opportunity to swim with whale sharks, diving in Cenderawasih Bay should be on every diver’s bucket list.

What Makes Cenderawasih Bay Special?

Cenderawasih Bay is part of the Cenderawasih Bay National Park, Indonesia’s largest marine park, covering over 1.5 million hectares. The park’s isolation has helped preserve its incredible biodiversity, making it a haven for aquatic life. The underwater landscape combines vibrant coral gardens, steep drop-offs, volcanic formations, and sunken war relics. However, the true highlight of diving in this area is the chance to encounter the world’s largest fish, the whale shark.

Unlike other places where whale shark sightings are seasonal, the whale sharks in Cenderawasih Bay are present year-round. They have formed a unique relationship with local fishermen, who use traditional fishing platforms called “Bagans.” The sharks gather near these platforms to feed on small fish that escape from the nets, offering divers a rare and intimate opportunity to observe these gentle giants in their natural habitat.

Diving Cenderawasih Bay is a truly unique experience, offering a blend of activities that cater to different diving interests. Here’s what you can look forward to:

Swim with Whale Sharks

The most remarkable aspect of diving in Cenderawasih Bay is the opportunity to swim alongside whale sharks. These gentle giants, which can reach lengths of up to 12 meters, are incredibly curious and often approach divers without fear. The whale sharks are frequently seen near the Bagans, where they gather to feed on fish scraps. Unlike in other locations where whale sharks are spotted briefly as they migrate, the interactions in Cenderawasih Bay tend to be longer and more relaxed, allowing for extended observation and photography.

Explore Pristine Coral Reefs

Cenderawasih Bay is part of the Coral Triangle, the epicentre of marine biodiversity. The reefs here are incredibly healthy and vibrant, thanks to the bay’s remote location and protected status.
