Apo Reef in Sablayan, Occidental Mindoro is considered to be one of the best scuba diving locations in the Philippines. It is a Marine Protected Area encompassing 34 square kilometers and it is the largest atoll-like reef in the Philippines.

I consider myself lucky to have scuba dived in Apo Reef twice! Both times have been memorable as this was where I saw a school of bumphead parrotfish and a school of barracuda for the first time!

About Apo Reef Natural Park

In 1980, former president Ferdinand Marcos officially declared Apo Reef as a Marine Park. Former president Fidel Ramos declared the entire reef as a protected natural park in 1996. Ten years later, the Department of Environment and Natural Resources (DENR) submitted the reef for consideration as a World Heritage Site to UNESCO.

Today, visitors accessing the Apo Reef need to pay an environmental fee of Php2,380 for locals and Php2940 for foreigners. The funds are used to protect the area.

Turning Apo Reef into a marine park has paid off and made it into a scuba diver’s paradise. Besides Tubbataha Reef in Sulu Sea, Apo Reef is one of the most famous dive sites in the Philippines. It has also become one of the most popular coral reef dive sites in the world.

Because it was declared as a Marine Protected Area (MPA), fishing within the reef was banned by the Philippine government. The MPA was opened as a tourist destination to help generate funds for its protection and to give alternative livelihood for the fishermen in the area.

Apo Reef Natural Park is located in Mindoro straight, 28 kilometers (roughly 2 hours) from Sablayan, Occidental Mindoro. The marine park consists of 3 islands, namely, Apo Island, Apo Menor and Cayos del Bajo. Apo Island, not to be confused with the one near Dumaguete, is the largest of these three. Apo Island serves as the base for the ranger station and campsite for the tourists.

Scuba Diving Experience in Apo Reef Natural Park

In all my dives in Apo Reef, I think I only saw one nudibranch. Apo Reef is known for the big stuff- groupers, snappers, tuna, jackfish, manta rays, white tip sharks and turtles. Even hammerhead sharks and whale sharks have been spotted here on occasion.  If you’re into underwater photography, this would be the perfect place to take out your wide-angle lenses.

Dive Sites in Apo Reef

There are at least 10 dive sites in Apo island ranging between 10 to 50 meters in depth. These sites are identified to have the best corals and sightings for pelagics and turtles!

Currents can be unpredictable and some sites are not beginner-friendly. So for you to fully enjoy Apo Reef, it is highly recommended that you are an experienced diver.

  1. South Corner- Top reef is a mixture of hard coral formations with sand patches. The wall is sloping down to 150+ ft, there are some ledges perfect for White tip sharks to rest.
  2. Ego Wall- This location is on the North West corner of Apo Island. This sheer wall dive has got a few interesting cuts to explore, the wall has a lot of sea fans, colorful sponges and soft corals.
  3. Mabuti Wall- The shallows are the perfect habitat for Black Tip Reef sharks; you can see Titan Triggerfish crushing coral with their powerful jaws.
  4. Shark Ridge- Based on the outer reef, shallows start at 10ft before the wall drops very deep. There are sand channels along the wall with some coral outcroppings covered in gorgonian fans.
  5. Ranger – This site is located right in front of the ranger station on Apo Island.
  6. North Wall – When the current is moving this is one of the best dives on Apo Reef. The top reef is covered in healthy hard corals with a few sand channels and gullies to explore.
  7. Shark Airport- This is one area where you can many White Tip reef sharks. The wall is in two parts, the first part ends in a large sand step between 60 and 90ft.
  8. Apo 29- This sea mount is for advanced divers only. The top of the reef is at nearly a 100ft and is a great nitrox dive.
  9. Hunters Rock- This site is actually 10 miles away from Apo Reef and can be an unpredictable dive that is good for advanced divers.
  10. Corde Point – This location has a large reef plateau with coral ridges and some smaller coral gardens.
  11. Apo Wreck- There is a wreck at 40ft which has some great coral growth.

During my visit in Apo Reef, I was able to dive in South Corner, Ego Wall, Mabuti and the Shark Airport. Most of the dives were deep and we would go beyond 30-meters trying to search for mantas, rays and sharks.

Apo Reef Diving Season

You can dive all year round in Apo Reef. The best time to scuba dive in Apo Reef is is from November to May. This is considered to be the “dry season” in the Philippines so there are lesser chances of rain.

Water Temperature and Visibility

On average water temperature in Apo Reef is 26 – 30°C. Visibility can go as far as 50 meters. It’s that crystal clear!

Dive Shops for Apo Reef

Pentagon Pro Dive Centre started its operations in 2015 by the Lontoc family. During my trip to Apo Reef in February 2019, I dived with one of the owners, Albert.

This dive trip was organized by a Manila-based scuba diver- Jeru Cajapin. I virtually met Jeru through Philippine Scuba Divers Facebook group. I did a bit of a background check and learned he’s organized several trips in the past with Pentagon. We also had a lot of common friends so I deemed it safe to go on a trip with him.

Please be careful with booking with independent scuba trip organizers as there have been reports of divers who got scammed by individuals claiming to be affiliated with certain dive shops. Do your due diligence before booking with freelance dive trip organizers.

Of course, you can also book directly with Pentagon Dive Center. But since I am a solo traveler and don’t have a permanent dive buddy, I thought it would be a good experience to meet other divers for this trip. Also, I didn’t want to worry about anything. I just wanted to pay, show up, dive and let the organizers do the rest.

Keep in mind that everything about this trip is basic and simple. You will be staying on the island itself where there is no cell signal. Electricity is only at night so you can charge your gadgets. Although there are showers and toilets, the water is salty. You can only have a real bath once you return to Sablayan town proper.

Food is brought in from the mainland. If you have special food requirements, you need to inform the travel organizer ahead of time. You must bring your own provisions and supplies as there are no stores on the island.

If you wish to dive with Jeru’s group, you can contact him via his Facebook account. Each trip has maximum of 14 divers and you instantly get new dive friends!

I went on this trip not knowing anyone… So happy I gained new dive friends!

If camping is not your thing, you can check out these other dive shops in Sablayan, Occidental Mindoro

3. Pandan Beach Resort

When you arrive in Sablayan you can hire a boat to take to Pandan Island. Pandan Island has its own dive shop, Mariposa Diving. They offer trips 2-3 times a week to go diving in Apo Reef

When I first visited Apo Reef in 2014, I opted to stay in Pandan Island with my dive buddy, Jem. I also recommend staying here as you can easily have access to the dive sites around Pandan Island.

I remember seeing a blue-spotted ribbon-tail stingray while snorkeling! And the biggest green sea turtle I’ve ever seen in my life showed up in their house reef! Pandan Island is definitely worth the visit!

If you dive with Mariposa in Pandan Island, they might require you to do a checkout dive in their house reef before diving in Apo Reef. You’re exempted if you’re at a certain Dive Certification level or if you have logged a certain number of dives. This is to see the diver’s abilities especially since not all dive sites in Apo Reef is suitable for beginners.

Apo Reef Liveaboard

Since Apo Reef is located along Mindoro Strait, you can dive Apo Reef even if you are coming from other islands in the Philippines. Several dive shops offer liveaboards from places like Coron in Palawan and Puerto Galera in Oriental Mindoro.

Apo Reef, Phlippines LiveAboards
Liveaboards for Apo Reef, Philippines

Apo Reef is 2 hours away from Sablayan town proper. Imagine if you want to do multiple dives in Apo Reef. So instead of going back and forth to Sablayan and Apo Reef, doing a liveaboard actually makes sense. Liveaboards in Apo Reef makes it practical for scuba divers to explore Apo Reef for several days at a time. No need to get back to land.

Apo Reef is a huge protected area so there is really much to see and explore. I have done around 10 dives combined in 2 trips. I feel like there is so much more to see. A liveaboard would be worth it!

Here are some Apo Reef liveaboards you can consider:

Atlantis Azores

Azalea Philippines

Dolphin Philippines

Infiniti Liveaboard


MV Discovery Palawan

MV Discovery Palawan

Oceanic 3

Reef Check for Apo Reef

In every place I go to, I like checking out the reef situation and what conditions they are in. While scuba diving in Apo Reef in February 2019, I saw a lot of bleaching and dead corals. 

A coral bleaching in Apo Reef.

I also noticed a lot of Crown of Thorns (CoTs). In each dive, I would spot around 5-10 crown of thorns. This is not good since the CoTs can easily consume vast amounts of coral in no time.

This Crown of Thorns (CoTs) is actually a starfish. It has venomous, long spines that cover its body. CoTs eat the corals and can destroy vast coral reef ecosystems.

Thankfully, I didn’t see or pick up any trash while scuba diving in Apo Reef. However, one of the divers from my group picked up a rice ladle while diving. This might have fallen from the tourist or liveaboard boats as sometimes the crew cook meals at the back of the boat.

Things to do in Apo Reef Natural Park

Even if you are not a scuba diver you can still enjoy your time in Apo Reef. You can do a bit of snorkeling or just chill by the beach. A good tech or social media detox is good for your soul. Besides, you don’t have a choice anyway since there is no cell signal in Apo Reef!

Apo island has a shallow lagoon. You can visit the lagoon and try to spot sea creatures hidden in the mangroves. The lagoon and mangroves forest serves as a food source, nursery and spawning ground for marine animals and birds. 

I recommend visiting the lighthouse on the island. It is an easy 10-minute walk from the campsite. The climb up to the lighthouse is also easy. Best of all, you will be rewarded with a breathtaking 360-degree view of the whole Apo Reef.

At night, lay out a mat on the beach and enjoy the most spectacular night sky. Don’t forget to watch out for shooting stars and make a wish!

I love stargazing while hearing the waves from the ocean.

Apo Island is also a nesting ground for sea turtles. You can walk the beach late at night or during sunrise to see if a mommy turtle has laid some eggs. You can report any new nests to the rangers. Since they keep a record of all the eggs in the island, check in with them if they are any turtles to be released in the wild soon.

While I was in Apo Island, I was very fortunate to witness a baby sea turtle, locally known as a pawikan, trying to find its way to the ocean!
