Once inside, you're surrounded by vertical limestone cliffs that rise high above the emerald water. These natural walls are covered in ferns, vines, and tropical foliage, giving the space a lost-world atmosphere.
Hong Island | A guide to this scenic lagoon escape & how to visit
Located in Phang Nga Bay National Park, Hong Island is a regular stop on James Bond Island tours from Phuket. The main highlight is the enclosed lagoon at its center, which you can access only by canoe during high tide. It's a short paddle through a narrow sea cave, opening into calm, shallow waters surrounded by limestone cliffs.
How to access Hong Lagoon?
Entry is only possible by canoe, typically with a local paddler as part of a guided tour. Boats anchor outside the cave, and access depends on tidal conditions.
Things to know before booking your Hong Island tour
- Hong Island is included in most James Bond Island tours, and tour prices vary by boat type and onboard experience.
- Big boat tours start at ฿1,665, speedboats at ฿1,800, and luxury catamarans at ฿3,300. Higher-priced options include extras like sunset views, dinner buffets, live DJs, and water activities.
- Access to Hong Lagoon is by canoe and depends on the tides. Boats anchor outside the island, and local paddlers guide you through a narrow passage.
- Canoeing at Hong Island may not be suitable for travelers with limited mobility. You'll need to step in and out of a small canoe from the main boat. The activity is guided and usually lasts around 20–30 minutes.
What to expect at Hong Island?
1/6
A lagoon hidden inside limestone cliffs
The island’s main attraction is its inland lagoon, surrounded on all sides by vertical rock walls. You can only access it by canoe through a small sea cave, creating a dramatic reveal that feels cut off from the open sea.
Paddling with local guides through sea caves
Steer through narrow inlets and caves, allowing you to sit back and soak in the scenery while learning about the island’s karst formations.
Escape the crowds of James Bond Island
While James Bond Island gets most of the spotlight, Hong Island offers a quieter, more nature-focused experience in Phang Nga Bay. It’s a chance to slow down, enjoy the calm water, and connect with the natural environment.
A tide-sensitive natural wonder
The lagoon is tide-dependent. During low tide, water levels may block canoe access altogether. At high tide, you can float right through the cave entrance. This changing access makes each visit slightly different.
Part of a protected national park
Hong Island is within Than Bok Khorani National Park, which protects its rich marine life, coral reefs, and coastal forests. It’s also home to birds, crabs, and tropical fish seen during canoeing.
Learn why it’s called “Hong”
“Hong” means “room” in Thai, a nod to the lagoon hidden like a secret chamber inside the island. The name reflects the island’s geography and sets the tone for the kind of tucked-away beauty visitors can expect.
What to see & do at Hong Island
Take in the limestone walls
Spot marine life in the shallows
Keep an eye out for small fish, crabs, and even mudskippers near the edges of the lagoon. If the tide is right and the water is clear, you’ll see the sandy bottom and schools of fish weaving between rocks and roots.
Pause for photos in the lagoon
Most paddlers will give you time to pause inside the lagoon for pictures. With the canoe floating in still water and limestone all around, it’s a stunning backdrop for wide-angle shots or quiet selfies.
Glide through side caves
Paddlers may take you into smaller side chambers or inlets branching off from the main lagoon. These mini-hongs or echo caves offer more intimate views of the limestone formations and are completely unreachable by boat.
