10 Best Snorkeling Spots in Vietnam to Visit

Ten Vietnam Snorkeling Spots Where the Guide's Call Beats the Photo

Ten beginner-friendly snorkeling spots in Nha Trang, Phu Quoc, Con Dao, and Hoi An, picked by how you get there and how hard it is.

When choosing a snorkeling spot in Vietnam, look at how you get there and what the current is doing that day before you look at how blue the water appears in photos. The same sea can mean jumping straight off a boat in one place and hiking through a forest in another, and the stamina required is completely different. This list gathers ten islands and entry points across Nha Trang, Phu Quoc, Con Dao, and Hoi An.

The order reflects whether a non-swimmer can start comfortably and how demanding the trip is. If you are a beginner or traveling with kids or parents, start with the Nha Trang islands at ranks 1 to 3; if you want to compare different scenery, look at the Phu Quoc picks at 4 to 6; and if you crave quiet and a bit of adventure, see ranks 7 to 10.

Visibility changes daily, so leave the final call to your local guide.

Hon Mun Marine Protected Area

This is the name that comes up first whenever Nha Trang snorkeling is discussed. Boats usually stop right over the reef and you slip in from the deck to look at the rock formations and fish. If you are not a confident swimmer, wear a life vest and practice breathing and fin kicks in the shallow zone your guide points out. It is a protected area, so never step on or touch the coral, and cut your time short if the water looks murky. Entry requirements and inclusions vary by operator (as of September 2026), so confirm them when you book.

Hon Tam Island

Beach time and snorkeling share one island here, which makes it a low-stress pick for families or friends who are not strong swimmers. Before getting into the water, practice putting on the mask and breathing on the sand to settle your nerves. Whether the island entry fee and snorkeling are bundled or charged separately differs by package, so ask at booking. When you rent gear, try the mask and life vest on yourself to make sure the mask seals and the vest fits properly.

Hon Mot Island

A frequent stop on Nha Trang island tours, this is a convenient place to see shallow coral and small fish within half a day. If you are on a package that hops between several islands, find out how much time you will actually spend in the water once transfers and meals are subtracted, so you do not feel shortchanged. Only enter in the area the guide points out and stay well away from the boat's propeller. On rough days, the captain and guide may change the plan, so keep your schedule flexible.

An Thoi Archipelago

This route zips between islands scattered off southern Phu Quoc by speedboat so you can compare a different underwater scene at each stop. Because the boat moves often, a half-day trip can feel rushed; a full-day tour is worth considering if you want to take it slowly. Ask the operator whether gear rental and lunch are included and how many snorkeling stops there are. Speedboats bounce, so prepare ahead if you get seasick, and recheck schedules and prices through official channels (as of September 2026).

Gam Ghi Island

On An Thoi Archipelago tours, this island is where people go for clear water and coral around the rocks, and it suits anyone who wants more time actually looking at the reef. Before entering, check with your guide for the stretch where the current is weakest, then move slowly inside the buoy line to save energy. If you have an open cut, it is safer to stay out of the sea that day. Rocks and coral sit close together here, so use gentle fin kicks rather than big strokes to avoid being pushed into them.

May Rut Trong Island

A small island that pairs fine white sand with calm stretches of water, it fits an itinerary of beach time plus light snorkeling. Do not head straight for the coral; get used to the mask and breathing in the shallows first, and beginners will feel much more at ease. During busy season the area near the pier gets crowded with boat traffic, so avoid swimming there. Facilities and fees on the island can change, so double-check current information when booking (as of September 2026).

Bay Canh Island

This is a boat destination within Con Dao National Park, where snorkeling comes with a close look at protected marine life. Check whether the national park permit is built into the tour, and if not, ask whether you pay it on site. During turtle nesting season, access to some zones may be restricted, so plans can change. Even if you spot wildlife, never touch or chase it; keeping your distance is the baseline, and you should not push closer for a photo.

Hon Tai Island

If you want a quieter side of Con Dao, this small island is worth putting on the shortlist; you go by boat to observe coral and fish. Telling the operator your swimming level and whether you get seasick before departure makes it easier to adjust the plan and entry zone. The weather around the island can shift suddenly, so trips are sometimes changed or cancelled, and following that decision is the safe choice. Operations and prices may change (as of September 2026), so confirm through official channels.

Cu Lao Cham Marine Protected Area

A marine protected area off Hoi An, it is commonly used for a day that combines swimming, snorkeling, and a look at fishing-village scenery. If your trip departs from Cua Dai pier, ask before booking whether gear and lunch are included and how long you stay on the island. Boats sometimes cancel when the sea turns rough, so leaving some slack in your schedule helps. Refund and rebooking rules after a cancellation differ by operator, so read the booking terms carefully.

Dam Trau Lagoon

Reached only by walking through a national park forest, this calm lagoon pairs a hike with coastal snorkeling and is meant for fitter travelers. Because the approach takes real walking, closed shoes, water, and sun protection beat sandals. It is remote, so avoid going alone and travel with a companion or a guide. Check tide times and your return schedule with the park office in advance, and plan to be back well before dark to keep things safe.

How to choose

If this is your first time or you are not a strong swimmer, the easy picks are number 2, Hon Tam Island, where you can acclimate on the beach, plus number 1, Hon Mun, and number 3, Hon Mot, which are nearby. To fill a whole day comparing several islands, go for number 4, An Thoi Archipelago; for a quiet, wilder feel, look at number 7, Bay Canh, and number 8, Hon Tai. If you have the stamina and like a walk, number 10, Dam Trau Lagoon, is the most special.

When comparing tours, confirm what the entry fee, gear, and lunch cover, how long you actually spend in the water, and the refund rules if a trip is cancelled. A spot that looks close on the map can still involve a long boat ride.

This information reflects the research date and fees and operations may change, so check official channels before you go.

Frequently asked questions

Can I snorkel in Vietnam if I'm not a strong swimmer?

Yes. At spots like Hon Tam, where you acclimate at the beach before moving to a shallow zone, a life vest is enough to enjoy it. When booking, tell your guide your swimming level so they can adjust where you enter the water.

When's the best time to go snorkeling in Vietnam?

Visibility at the same spot can change dramatically with monsoon winds and the previous night's rain, so a local guide's judgment on the day is more accurate than any fixed best season. If you are going in a rainy or windy period, ask the operator about their cancellation criteria in advance.

What should I avoid to protect the coral while snorkeling?

Do not stand on or touch the coral, and do not scatter food to attract fish. Rather than diving down hard for photos, move slowly inside the buoy line, which is better for both the ecosystem and your own safety.

What should I check before booking snorkeling in Con Dao?

Check whether the national park permit is included in the tour. During turtle nesting season, access to some zones may be restricted, so your plan could change.

Who is Dam Trau Lagoon right for?

It is reached on foot through national park forest, so it suits travelers with a reasonable level of fitness. It is remote, so do not go alone, and confirm tide times and your return schedule at the park office.

What should I ask about multi-island tours?

Ask how much time you will really spend in the water after transfers and meals, and whether gear and lunch are included. Enter only in the area your guide points out and stay clear of the boat's propeller.
