Twin Caverns diving site is under the Danajon Bank Double-Barrier Reef

Twin Caverns is a dive site featuring two caverns on Danajon Double-Barrier Reef, one of only six double-barrier reefs in the world. Divers begin their descent on the vertical wall and drift to the entrance of the first cavern, reaching a maximum depth of 30 meters.

The second cavern is the flashlight fish bowl at the back of the cave. Cover your torch beam to see nature’s bioluminescent display. The vertical wall is completely encrusted with hard corals, with tropical fishes and invertebrate sea life moving around.

We can bring you to Twin Caverns in about one hour from our Mactan dive center headquarters. We will leave at 09h00 (9:00 AM) on a full day diving safari, complete two dives, and return to our pier before dusk.

Why should you explore Twin Caverns?

Inside Twin Caverns Danajon Bank is one of only six double-barrier reef systems in the entire world. So, if double barrier reefs are extremely rare and twin caverns are rare, how rare is it to find twin caverns as part of a double barrier reef? This might literally be a unique scuba diving opportunity. You need Advanced Open Water certification, night diving experience, and 50 logged dives to dive Twin Caverns.

Diving Twin Caverns feels like diving several sites in one dive. We will start by descending on a vertical wall that stretches from 5 meters down to 40 meters (15 feet to 130 feet). Then, we will begin our drift dive. Visibility will be 10-30 meters (30-100 feet). At a depth of 30 meters (100 feet), we will soon reach the openings of two neighboring caverns and begin two distinct cavern dives.

The second dive of the day is your choice. We can dive Twin Caverns again, we can dive elsewhere on Danajon Bank, or we can dive at one of the many sites off Olango Island or Mactan Island. There are quite a few dive sites between Twin Caverns and Scotty's Dive Center.

What can you see inside Twin Caverns?

Going to the Twin Caverns Starting with the vertical wall, species of hard coral cover it completely. Among the hard corals, you will observe various tropical fishes and invertebrate sea life.

Outside Twin Caverns, you will see table corals, sea fans, and tube sponges. Whitetip sharks and groupers will be our welcoming committee. The whitetip sharks might stay down around 45 meters (150 feet), however.

Inside Twin Caverns, we will enjoy a wonderful light show. The grotto at the back of one of the caverns is home to a school of flashlight fish. Cover your torch beam to marvel at how these flashlight fish light up the water like fireflies. If that sounds amazing, remember this: only Scotty's Action Sports Network can bring you here!
