Hon Mong Tay vs Hon Gam Ghi for Snorkelling

Hon Mong Tay is the better pick for beginners and families, because its corals sit near the surface and the stop is short and easy. Hon Gam Ghi suits more confident snorkellers, since its reef on the north coast is sheltered from waves and current, but facilities are basic. Mong Tay is only sometimes on tour itineraries, while Gam Ghi is a common stop.

How do the water and corals compare?

Hon Mong Tay has corals near the surface, so photos and observation are easy even in shallow water. It is one of the most popular diving spots in the north of the island, and the water is clear when the sea is calm. The stop is short, which suits first-time snorkellers who want a gentle start.

Hon Gam Ghi has a reef along the north coast that is sheltered from waves and current. Underwater, you will find rock formations, crevices and small caves, which makes it a good place for snorkellers with some experience. The coral closest to the beach is in poor condition, so do not stand on the reef.

Which beach and facilities suit you?

Hon Gam Ghi is almost always a snorkelling stop rather than a beach stop, and some tours do not land on the island at all. If you want to sit on sand and use a toilet, Hon Mong Tay is the better fit for a short break, and Gam Ghi is for the water.

Gam Ghi has no restaurants, toilets or shops, so pack everything you need. Camping there is possible only if you bring all your own supplies, since there is no electricity or running water. Operators and local sources report this rule, so confirm the current position on WhatsApp or on the beach before you plan an overnight stay.

Which has more crowds, and when should you go?

Crowds depend on how many tour boats arrive at the same time, and both stops can feel busy in peak season. The best window for both islands is November to April, when the water is clearest and the sea is calm. Late November to mid-December is jellyfish season, peaking in early December, so check your dates if you are sensitive to stings. If crowds worry you, ask your operator how many boats will be at the same stop, and whether an earlier departure is possible.

In the rainy season, boats are cancelled when the sea is rough and visibility drops. Some tours give only 30 minutes in the water at Gam Ghi, which feels rushed. Ask how long your tour stays in the water before you book.

Which is better for beginners?

Hon Mong Tay is the better choice for beginners. Its corals are close to the surface, and it is ideal for snorkellers who are still building confidence. A snorkel-focused tour with smaller groups and more guide support in the water is the best choice for a first trip.

Hon Gam Ghi is best for intermediate and advanced snorkellers who want to explore a unique ecosystem. If you are a first-timer, you can still visit, but choose a tour that gives you enough time and guide support.

How can you see both in one day?

Popular stops include Gam Ghi, Buom, Xuong, May Rut and sometimes Mong Tay. A day that includes both is possible, but the time in the water can be short once travel is counted. Speedboats and canoes reach Gam Ghi in 15 to 20 minutes, while wooden boats take 45 to 60 minutes, which cuts into swim time.

Snorkelling-focused tours centre on coral sites rather than beach bars or photo stops, so they are the best way to see both islands without rushing. Ask the operator how many minutes you will spend at each stop, and whether the boat will land on Gam Ghi.

Checklist before you book:

• Which stop is the first one, and how long is the swim at each?
• Is the tour snorkel-focused, with smaller groups and guide support?
• Does the boat land on Gam Ghi, or is it a snorkel-only stop?
• What is the plan if the sea is rough?

Snorkel gear matters at both stops. Some tours provide a mask, snorkel and fins, but fins may not be available in children’s sizes, so families should check before the day. Ask whether the guide will check your fit before you enter the water, and whether a life jacket is worn in the water for beginners. Operators and local sources report that rules on life jackets apply on the boat as well, so confirm the current rule on WhatsApp or on the beach.
