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.

  • 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.

What to see & do at Hong Island

Take in the limestone walls

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.

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.

  • Hong Island (Koh Hong) lies in Phang Nga Bay within Than Bok Khorani National Park, northeast of Phuket.
  • Most travelers visit as part of a guided full-day tour from Phuket/Krabi/Phang Nga, typically by speedboat, catamaran, or big boat, combined with stops like James Bond Island, Panak Island, and Koh Panyee.
  • National Park fees apply separately—THB 400 per adult & THB 200 per child—and must be paid in cash upon arrival if it’s not included in your tour.
  • Time of day: Visit between 10am and 2pm for calm waters and great lighting inside the lagoon. This is also when most canoeing happens due to tide conditions.
  • Time of week: Weekdays are your best bet to avoid the crowds, as weekends tend to be busier with both local and international tour groups.
  • Time of year: November to April is the dry season in Phang Nga Bay, offering sunny skies, calm seas, and the most reliable access to the lagoon.
  • The main attraction—the lagoon—is only accessible via small inflatable canoes paddled by trained local guides. You won’t be paddling yourself.
  • Guests need to be able to sit low in a canoe and transfer from the main boat, so this activity may not suit people with mobility limitations.
  • Swimming and walking around inside the lagoon are not allowed. This helps preserve the delicate marine and limestone environment.
  • Access to the lagoon is tide-dependent. If the tide is too low or too high, your canoe may not be able to enter the cave tunnel.
  • Wear quick-dry clothing and sandals or water shoes, as you’ll get wet while entering and exiting the canoe.
  • Bring a waterproof phone pouch or dry bag to protect your electronics and valuables during the canoe ride.
  • A hat, sunglasses, and reef-safe sunscreen are useful for the boat ride, but not always necessary inside the shaded lagoon.
  • Space is limited on the canoe, so avoid bringing bulky bags or unnecessary items when disembarking from the main boat.
