Snorkeling is a “must-try” activity when visiting the Pearl Island. However, not every spot with seawater has beautiful coral. If you don’t choose the right location and time, your experience will just be “swimming with goggles on.”
The traveler’s pain point: Snorkeling or… “torture”?
Many of you have shared with me: “I went on a snorkeling tour, but why did I only see rocks and dead coral?” The current reality is that due to climate change and over-tourism, many near-shore reefs have been damaged. Additionally, going on days with big waves or choosing the wrong beach without understanding the currents results in murky water where you see nothing but the feet of the person swimming next to you.
In this article, I will name the specific coordinates that still harbor vibrant living coral reefs and how you can enjoy them to the fullest.
Which season is best for Phu Quoc snorkeling?
This is the most important question. Phu Quoc has two distinct seasons, and snorkeling locations must change according to the season to ensure clear water and calm waves.
- From November to April (Dry Season): This is the “golden time.” The Northeast monsoon blows lightly, the sea in the South Island is as calm as a lake, and the water is crystal clear right down to the bottom. This is the peak time for Phu Quoc Snorkeling at the southern islands.
- From May to October (Rainy Season): The Southwest monsoon blows strongly, waves in the South Island are often large, and the water is murky. During this time, I usually advise guests to head toward the North Island (Ganh Dau area) or snorkel in sheltered spots.
Local tip: Never go snorkeling the day after heavy rain. Rainwater flowing from the forest carries sediment that clouds the seawater, making visibility extremely poor even during the dry season.

Top 5 “top-tier” Phu Quoc snorkeling spots
Hon Gam Ghi (Dam Ngang) – The coral kingdom of the South Island

If I had to choose just one place for Phu Quoc snorkeling, I would pick Hon Gam Ghi. This place owns hard coral reefs and giant plate corals with a thick density right near the surface.
- Characteristics: Extremely shallow water (only 1m – 3m); you just need to look down to see a vibrant world.
- Practical insight: Because the water is shallow and there are many submerged rocks, you absolutely should not stand up or trample to avoid breaking the coral and to prevent sharp oysters from cutting your feet.

Coral Park (South Island) – 5-star Sea Walker experience

If you don’t know how to swim but still want to “walk” on the seabed like on land, this is the place for you. Instead of wearing a mask, you will wear a copper helmet that provides continuous oxygen.
- The experience: You can personally touch rare coral reefs that have been meticulously cultivated and let schools of fish surround you.
- Note: The cost here is higher than traditional tours but extremely safe and professional on large cruises like the Nautilus.

Hon May Rut Trong & May Rut Ngoai

These two islands often appear in the Phu Quoc 3-Island Tour. While May Rut Trong is famous for its long sandy beach, May Rut Ngoai has rocky coral reefs and many small, friendly fish.
- Tip: Bring a small piece of bread in a waterproof bag. When you go into the sea, just squeeze the bread lightly, and hundreds of sergeant major fish will swarm around you – a perfect check-in moment!
Hon Mong Tay (North Island)
Don’t confuse this with Hon Mong Tay in the South Island. Hon Mong Tay in the North near Ganh Dau is a fairly pristine Phu Quoc snorkeling spot. There are fewer tourists here, so the coral retains its natural beauty and the water is very blue.
Coral reefs at Ganh Dau
This area is suitable for those who like self-guided exploration. You can hire a boat from locals to take you to reefs about 1km from shore. However, services here are not as professional as in the South; you need to prepare high-quality snorkeling gear yourself.

“Survival” guide and civilized diving practices
To have a trip to see where the beautiful coral snorkeling in Phu Quoc is while staying safe, keep these “hard-earned” experiences in mind:
- Avoid thermal shock: Phu Quoc seawater sometimes has sudden cold currents. Before entering the water, splash seawater on your body to acclimatize, avoiding entering too quickly which can cause cramps.
- Protect the environment: DO NOT apply sunscreen right before snorkeling (chemicals in sunscreen kill coral). Use “Reef Safe” sunscreens or wear a long-sleeved swim shirt (rash guard) for natural sun protection.
- Check equipment: Always check if the mask leaks or if the snorkel has water before leaving the side of the boat.
- Seasickness: If you are prone to seasickness, take medicine 30 minutes before boarding and jump in as soon as the boat stops. You will feel much better in the water than on the boat.
A warning from a local: Absolutely do not touch, break, or stand on the coral. A branch of coral takes decades to grow just a few centimeters but takes only 1 second to be destroyed by a careless step.
