Panak Island lies just west of James Bond Island in Phang Nga Bay and is celebrated for its dramatic limestone cliffs, tidal sea caves, and secret lagoons. Unlike many other islands in the area, you won’t actually set foot on Panak, as exploration here is done exclusively by canoe, paddled by experienced local guides through narrow tunnels and into hidden hongs (lagoons).

Things to know before visiting Panak Island

  • Panak Island is included in select James Bond Island tours that highlight cave canoeing and bioluminescent experiences. 
  • Tour prices vary depending on the vessel and experience. Big boat tours start from ฿1,665, while bioluminescent speedboat and canoe tours range from ฿3,390 to ฿3,735. These premium options often include dinner, sunset views, and unique paddling opportunities after dark.
  • Canoeing at Panak Island is tide and cave-dependent. You’ll paddle through sea caves and mangrove tunnels, with access determined by water levels and cave conditions on the day.
  • This activity may not be suitable for travelers with limited mobility. You’ll need to transfer from the main boat into small inflatable canoes, often while at sea. Canoe rides typically last 20–30 minutes, depending on the cave route and tide.

Sea caves & secret lagoons

Canoeing through low tunnels opens into hidden lagoons surrounded by cliffs and jungle. These hongs feel like lost worlds, cut off from everything.

Natural light & eerie silence

Inside the caves, sunlight reflects off the water, casting a soft glow. The only sounds? Dripping water and the occasional bird call.

Paddle through limestone tunnels

Navigate narrow passageways under dramatic overhangs and between towering karst formations, a dream for photographers and adventurers alike.

Mangroves & wildlife

Some hongs open into thriving mangrove forests. Spot monkeys, mudskippers, colorful crabs, or even hornbills as you paddle through.

Magical bioluminescence

In some caves, night tours reveal glowing plankton in the water. Paddle through and watch the sea sparkle with every stroke.

Unspoiled serenity

Unlike the more crowded spots in Phang Nga Bay, Panak Island offers a quieter, more intimate escape into nature’s wonders.

What to see & do at Panak Island

Canoe into Diamond Cave

One of the most popular cave systems here, Diamond Cave sparkles with mineral crystals and opens into a hidden lagoon.

Explore Bat Cave by day

Paddle silently into Bat Cave, named for the colonies that live inside. You'll hear them chirping as you glide beneath their roosts.

Drift into mangrove lagoons

Some canoe routes end in lush mangrove forests—calm, green, and full of life. These tranquil spots feel completely untouched.

Know before you go

  • Panak Island (Ko Pa Nak) is located in Phang Nga Bay, surrounded by towering limestone cliffs and tidal caves. It's usually the first stop on full-day tours from Phuket, Krabi, or Phang Nga.
  • Most travelers visit as part of a guided full-day tour from Phuket/Krabi/Phang Nga, typically by a canoe, combined with stops like James Bond Island, Hong Island, and Koh Panyee.
  • However, it is also possible to visit independently. You can hire a longtail boat or rent a speedboat from local piers near Ao Phang Nga National Park.
  • 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: Panak Island is best visited in the morning, when tide levels are ideal for canoeing into caves and lagoons. Most tours stop here before 11am.
  • Time of week: Visit on a weekday to avoid crowds, especially during Thailand’s peak travel season (Dec–Feb). Weekend trips can get busy.
  • Time of year: November to April offers calm seas and optimal visibility for cave exploration. In the rainy season (May–October), some caves may be inaccessible due to water levels.

  • You’ll need to transfer from the main boat into the canoe, which may be difficult for guests with mobility issues.
  • Swimming or walking inside caves is not permitted to preserve natural limestone structures and minimize disturbance to wildlife.
  • Tours may skip Panak if tides are too high or low—final decisions are made by experienced crew for guest safety.

  • Wear light, quick-dry clothes and sandals or water shoes. You’ll get splashed while transferring in and out of canoes.
  • A dry bag or waterproof phone pouch is highly recommended to protect your valuables during the cave paddle.
  • Bring sunglasses, a hat, and reef-safe sunscreen for the open boat ride. Inside the caves, it’s shady and cool.
  • Avoid large bags or extra gear as space on canoes is tight, and anything not waterproof should stay on the main boat.

  • Use a guided boat or kayak: Panak Island is uninhabited and accessible only by water; guided tours ensure safe navigation through caves and lagoons.
  • Follow designated paths: Stick to marked or boat-accessible areas to protect fragile limestone formations and avoid getting lost.
  • Respect wildlife: Avoid disturbing bats in the Bat Cave and marine life in surrounding lagoons.
  • Wear appropriate footwear: Water shoes or non-slip sandals help with slippery rock surfaces and cave entrances.
  • Bring a waterproof camera or case: Capture stunning caves, lagoons, and limestone cliffs safely without damaging your devices.
  • Carry minimal personal items: Space is limited in kayaks or small boats—keep only essentials and secure loose belongings.
