Gam Ghi Island: Best Coral Reef for Snorkeling in Phu Quoc
11/02/2025Gam Ghi Island is often called one of the best snorkeling spots in Phu Quoc. But here’s the truth: not everyone has the same experience here.
Some travelers leave amazed by the crystal-clear water and colorful coral reefs. Others feel disappointed, seeing nothing but cloudy water and crowded boats.

It’s not the island itself. It’s when you go and how you visit it.

Discover Phu Quoc’s Coral Kingdom – Gam Ghi Island

Nestled within the An Thoi archipelago, Gam Ghi Island (or Dam Ngang Island) is a pristine paradise waiting to be explored. True to its name as the Coral Kingdom of Phu Quoc, the reef here spans thousands of square meters, lying just beneath the surface, shallow enough to explore without diving.
Above the waterline, white sand, coconut palms, and rugged rock formations make it feel like a wilder, quieter version of Bali.
But many visitors leave underwhelmed and it’s rarely the island’s fault.

Top activities worth your time at Gam Ghi Island
Gam Ghi island has no resort, no restaurant, no beach club. It offers something rarer: untouched nature and one of Phu Quoc’s best reefs.
Here’s what’s genuinely worth your time.
Snorkeling the coral reef
Snorkeling in Gam Ghi Island is the main reason people visit here.
The reef is shallow (2–5m), beginner-friendly, and still genuinely alive. On a clear morning, visibility can reach 8m.
You can expect:
- Colorful coral formations
- Small tropical fish
- Good visibility in dry season

Practical tip: The best times is 7:30–9:30 AM. After that, boat traffic often makes the water noticeably murkier.
Discover why Gam Ghi and other best snorkeling spots in Phu Quoc are must-visits for sea lovers. Book your adventure today!
Kayaking along the island’s edge
The shoreline hides small coves and rock formations invisible from the main beach. A kayak gets you into those spaces in a way swimming can’t.
- Budget 45–60 min for a relaxed loop around accessible sections
- Water in sheltered coves is calm — fine for first-timers
- Bring a dry bag — you will want your phone for photos
Relaxing on pristine beaches
No vendors, no speakers, no sunbed rows. The beach here is genuinely quiet, something increasingly rare in Phu Quoc. Use the downtime between snorkeling sessions to actually rest.
- Walk 5 minutes away from the main drop-off for quietest spot
- Shade is limited so bring reef-safe sunscreen and a UV rash guard

Short walks on the rocky trails
The island is tiny, crossable in 15 minutes. But the elevated rocky sections give you a rare overhead view of the reef and surrounding islands that most day-trippers never see.
- Wear closed shoes, rocks are uneven and slippery
- Go at midday when others rest, you’ll have the viewpoints to yourself
Stand-up paddleboarding (SUP)

If your tour includes SUP, it’s worth trying once.
The sheltered water makes this ideal for beginners. Less a workout, more a slow way to glide above the reef and see into the water from a unique angle.
Falling in isn’t a problem. The water is warm and usually calm around the board area.
Practical tip: Check in advance if it’s included. Some tours charge extra despite advertising it.
Visiting local villages

While Gam Ghi Island itself is uninhabited, nearby islands such as Hon Thom (Pineapple Island) and May Rut island offer a glimpse into local life.
You can:
- Visit fishing villages
- Try fresh seafood
- Learn more about local culture
This adds depth to your overall Phu Quoc travel guide experience.
Group tour vs. private boat: what actually makes sense
Most people think Gam Ghi island Phu Quoc is either “amazing” or “overrated.” In reality, it depends on how you visit it.
Group tour: cheap but limited
Group tours are the most popular option:
- Budget-friendly
- Include 3–4 islands + lunch
- Easy to book
But there are trade-offs:
- 10–25 people per group
- Fixed schedule
- Only 30–60 minutes snorkeling
The biggest issue?
👉 You don’t control the timing. If Gam Ghi is not the first stop, water clarity is often worse.
Private speedboat: more control, better experience
A private trip changes everything:
- You choose departure time
- You decide how long to stay
- You can go early before the crowds
Best for:
- Small groups (4–6 people)
- Travelers who care about snorkeling quality
- Anyone who wants a more relaxed experience
If snorkeling in Phu Quoc is your priority, this option makes a huge difference.

- Don’t leave trash behind
Responsible travel is what keeps this place worth visiting.
