Raja Ampat Biodiversity Resort’s house reef displays the extraordinary underwater life of the region. The reef flat and reef wall host a vibrant marine life where hundreds of bright-colored fish swirl above the corals. Lucky snorkelers might also come across a sea turtle, a manta ray, or a crocodile fish.

How to get to Biodiversity Resort

Only guests of the Raja Ampat Biodiversity Resort and the neighbouring homestays (Monkairi Homestay and Yenanas Paradise Homestay) can access this spot.

The spot is located on Gam island, in the heart of Raja Ampat archipelago. After catching a flight to Sorong, you have to take the ferry to Waisai (leaves at 9 a.m and 2. p.m., check before traveling). From there you will be picked up by a boat sent by the accommodation where you made a reservation.

Water entrance for snorkeling Biodiversity Resort house reef

You can enter the water almost anywhere you wish from the beach. If you want to explore the northern side of the reef (where a small rock emerges – see map), walk to the northern end of the beach and enter the water there.

Biodiversity Resort house reef snorkeling exploration

The whole house reef can be snorkeled. From the pier to the southern tip of the beach (on your right while facing the sea), the reef flat is around 50m wide, which makes the reef wall easily accessible.

North of the pier, the reef flat widens progressively and reaches the rock (called “batu lima”, see map) which emerges from the bay, around 300m away from shore.

Near the drop off, look for the green sea turtles that come to rest in the bay.

Raja Ampat coral reefs are well known for their richness and diversity and this spot is no exception. The reef flat and the reef wall are covered by a wide variety of hard corals and soft corals, sea fans, sponges and sea lilies.

Hundreds of damsels and sea goldies swirl around over the reef, where you can see clown triggerfish, regal angelfish, butterflyfish, and surgeonfish. Sometimes, a green turtle calmly crosses the reef.

Be on the watch of schools of barracuda often sheltering below the reef edge, and, during the season, of manta rays visiting the bay.

Crocodile fish at Raja Ampat Biodiversity Resort
The crocodilefish is occasionally spotted on the reef.

If you spend a few days here, try night (or dusk) snorkeling. It is the perfect occasion for observing species that live hidden during the day, such as the walking sharks, which have learned to “walk” on the seabed with the help of their fins.
