Is Cham Islands snorkeling good?
Yes, Cham Islands has the best snorkeling near Hoi An — visibility 5–15m, healthy coral, diverse fish. Best season: March–August (calm water, clear). Hon Mun is the top spot. Tours: 350k–500k VND include gear, lunch, boat. October–November: rough water, poor visibility, tours often cancelled.
The short answer
Yes, Cham Islands has good snorkeling — the best you’ll find near Hoi An. It’s not Nha Trang (better marine diversity) or Phu Quoc (clearer water). But for central Vietnam, it’s solid.
What you’ll see:
- Tropical fish: clownfish, parrotfish, angelfish, butterflyfish
- Coral: hard coral (brain coral, staghorn), soft coral (sea fans)
- Other: sea cucumbers, starfish, occasional sea turtles
What you won’t see:
- Sharks (gone from this area)
- Rays (rare, deeper water)
- Massive coral walls (this isn’t Indonesia)
Best snorkeling spots
Hon Mun (the best)
Depth: 1–5m Visibility: 10–15m (good season) Coral: Healthy hard coral, diverse fish Current: Mild
Hon Mun is the flagship spot. The water is clear, coral is healthy, and fish are abundant. You’ll see clownfish darting through anemones — the Finding Nemo experience.
Best for: All levels, especially beginners.
Hon Tai
Depth: 1–3m Visibility: 5–10m Coral: Patchy, some bleaching Current: Very mild
Hon Tai is shallower and calmer. Good for first-timers who are nervous. Coral is not as healthy — some bleaching from past heat waves. But fish are still around.
Best for: Nervous swimmers, families with kids.
Bai Chong (beach snorkeling)
Depth: 1–4m Visibility: 5–10m Coral: Near the shore, accessible Current: Mild
Bai Chong is a beach on Hon Lao (main island). You can walk in from the shore and snorkel without a boat. Coral is close to the beach — convenient, but not as pristine as Hon Mun.
Best for: Independent travelers, people who want flexibility.

Verdict: First-timers should take a tour. The price difference is small, and having a guide matters.
What to bring
- Reef-safe sunscreen: Regular sunscreen damages coral. Buy at Hoi An pharmacies (Biore, La Roche-Posay — 200k–400k VND).
- Underwater camera: GoPro or phone with waterproof case. Fish are close — you’ll get good shots.
- Rash guard: Protects from sun and jellyfish stings.
- Towel: Tours don’t provide.
- Dry bag: Keep clothes dry on the boat.
Environmental notes
UNESCO Biosphere Reserve (since 2009) means:
- No coral touching (fines up to 5M VND)
- No fish feeding (disrupts ecosystem)
- No plastic bottles on islands (bring reusable bottle)
- No anchoring on coral (boats use mooring buoys)
Plastic ban: Cham Islands banned single-use plastics in 2018. Vendors use banana leaves, bamboo straws. Bring a reusable water bottle.
My recommendation
Book a morning tour (departs 7:30am from Hoi An). You’ll hit snorkeling spots by 9am — best visibility, calmest water.
Bring your own mask if you have one. Tour gear is functional but not premium. A proper fit matters for comfort.
Don’t touch coral. It’s fragile, takes decades to grow, and you can get cut. Look, don’t touch.
Expect to see fish, not walls of coral. Cham Islands is good for a half-day trip from Hoi An. If you’re a serious diver, go to Nha Trang or Phu Quoc.
