The Irako (along with the Okikawa) is debated to be best wreck dive in the Philippines. The Irako almost completely intact and has very good visibility you know yo u are on a big shipwreck. Big schools of yellow fin tuna, groupers, lion fish and scorpion fish surround this wreck. To date two permanent residents (2 sea turtles) live in the crumpled superstructure. There is also a huge column of Jacks inhabiting the bow area.
There is a beautiful deep penetration dive through the engine room for well trained, properly equipped divers.
Due to it’s location, The Irako usually has the best visibility of all the wrecks in Coron Bay.

The Akitsushima a Japanese Seaplane Carrier is located at N 11*59. 218′, E 119*58. 417′
The Akitsushima was a seaplane carrier with a displacement of 4724 tons, a length of 118 meters and was 15.7 meters wide. Powered by four diesel engines driving twin propellers, creating a total of 8000 shp, and producing a maximum speed of 19 knots
Akitsushima was also armed with 10 piece, 25 mm anti-aircraft guns, four piece five inch (50 cal) guns and carried one large Kanwanishi flying boat.
The Akitsushima was a large warship, now laying on her port side. She was struck by a large bomb close to the stern where the flying boat rested on the metal tracks and sank immediately. The ship was almost torn into two pieces. The flying boat disappeared upon impact.
The crane used for lifting the seaplane is still intact. The crane is lying on the sandy bottom and attracts schools of batfish and barracudas and the odd grouper. One 3-barreled AA (anti-aircraft) gun is still present at the front of the flying boat tracks. This is a fascinating dive where you can see all sorts of marine life around the wreck.
Due to the depth and various jagged metal hazards within, no dives (swim throughs) are allowed without a wreck diver certification. Wreck divers can make an impressive penetration into the engine room to see the four engines and the gears and machinery for operating the crane are the main objects of interest for a penetration dive.
This dive is best made using a 30% or 32% Nitrox mix for a 50% increase in allowable submersible time.

“A must do Dive”
“One of the most Bizarre dives in the Philippines.”
“See the thermal layers and do underwater climbing”
Barracuda Lake is located at the North end of Coron Island. This amazing dive starts with some challenging mountain climbing, sometimes in full diving equipment, over sharp limestone cliffs. Wear tennis shoes or sandals and carry your fins on your tank. The climb only takes 10 or so minutes and the exertion is worth it. The scenery is spectacular and the underwater terrain is some of the most interesting you will see anywhere on the planet. The top 4 meters is warm fresh water and below 4 meters the water is saline. There are dramatic changes in water temperature from 28 to 38 Celsius. You can even see the thermoclines at 4 and 13 meters. At 34 to 35 meters the water changes from crystal clear to medium brown. If your lucky, you might even see the local resident barracuda approximately 1.5m long that likes to guard this majestic domain. This is definately a dive that you should not miss!
Barracuda lake’s maximum depth: 35 meters.
Recommended certification level: Open Water Diver, Mountain Climbing Diver Specialty.
The Cave in Barracuda Lake
There is a very deep cave in Barracuda lake entered at a depth of 33 meters. The cave has been marked with a guide line on the right side as you enter. The cave is large enough for only one diver to swim in and turn around at a time so please wait your turn. The silt and sediment on the bottom is packed and should remain undisturbed by the diver. This cave is quite dark and the sediment is also quite which gives it an eerie sensation. Proper dive equipment would include a light and at least an octopus with a 7-foot hose or other secure source. The current tells you that it is connecting Barracuda Lake to the ocean. This is a dive that you should not miss but you must make sure you are prepared..
The Cave Maximum depth: 40 meters, please use extreme caution below 40 meters.
Recommended certification level: Limiting your penetration dive to 40 meters total distance from the surface (a 6 meter penetration) then Advanced Open Water Course with Deep Diver Specialty or Cavern Diver Specialty should be enough. Should you plan to penetrate beyond 40 total meters from the surface then you should be a Cave Diver with extensive experience and carry the necessary safety equipment.
The Cathedral cave under Coron Island, Palawan and directly connected to the sea. It’s located on the East side of the South end of Coron Island.
Cathedral Cave is a fantastic dive spot. It starts at6 meters deep at a hole next to the sheer rock wall of Coron Island. You enter a tunnel and descend to 13 meters.
Then you pass out of the tunnel and see a ray of light that penetrates the interior of a cave. The skeletal trunk of a sunken tree and main branches of the tree rest on top of a sand mound in the middle of the cave. Following the light you pass over the sand dune and continue ahead to the left towards another passage that leads to a chamber with an air pocket above sea level. Again back through the tunnel into the open sea where you dive among the beautiful corals with great visibility. Cathedral Cave MUST ONLY BE ATTEMPTED in calm weather never attempt to enter the Cave in a storm surge and large waves.
