We did the “Luxury Small Group Phi Phi Sunrise” tour with Simba Sea Trips our second tour with them in the space of a few days and it was another standout experience. The early start is absolutely worth it. Sunrise over the islands (and from the boat) was something else, and getting out ahead of the crowds made a huge difference to the whole day. The team were excellent once again friendly, organised, and everything ran on time, including the morning pickup which was spot on. The snorkelling was a real highlight. We saw a huge moray eel (very chonky boy), two sea snakes (a first for me), several sharks, and plenty of beautiful fish. Easily some of the best marine life I’ve seen on a tour like this. The whole day felt relaxed and well-paced, never rushed, and just genuinely enjoyable from start to finish. We booked Simba twice within a few days for a reason if you’re considering Phi Phi, this is definitely the way to do it.
Hong Island, Phang Nga Bay: Sea Caves, Hidden Lagoons and Kayaking
Hong Island is one of the natural highlights of Phang Nga Bay — a place where the landscape turns inward, drawing visitors through shadowed sea caves and out into the still, emerald calm of hidden inner lagoons. The word ‘hong’ means ‘room’ in Thai, and the description is apt: these enclosed, cliff-ringed spaces feel like secret rooms, accessible only to those who know where to look and when the tide is right. It is one of the most memorable stops on Simba Sea Trips’ Phang Nga Bay tours from Phuket, and a particular favourite among travellers who want their day on the water to feel like a genuine adventure rather than a sightseeing circuit.

The Hongs: Nature’s Hidden Rooms
The inner lagoons of Hong Island are only accessible through narrow cave entrances at the base of the limestone cliffs — and only when tidal conditions permit. This inaccessibility is precisely what makes them so special. You transfer from the speedboat into a stable sea canoe, crouch as the guide paddles you through the low cave passage, and then emerge into an enclosed world where the cliffs rise vertically on all sides, vegetation hangs from the rock above, and the water is the colour of pale jade. The transition from darkness to light, from the narrow tunnel to the open lagoon, is one of those moments that consistently surprises guests who have seen photographs but could not quite anticipate the feeling of it in person.
Sea Canoeing and Kayaking Through the Caves
The sea canoeing experience at Hong Island is one of the most peaceful ways to experience Phang Nga Bay. Stable, open canoes are paddled by experienced local guides who navigate the cave passages with quiet confidence — guests simply sit, observe, and let the experience unfold. No paddling experience or physical fitness is required, making the activity accessible to virtually all guests regardless of age or fitness level. Inside the cave tunnels and lagoons, the guides will often pause to allow guests to take photographs, listen to the sounds of the space, and appreciate the ecosystem that exists in these remarkable hidden environments.
Wildlife and Ecosystem
The caves and lagoons of Hong Island support a distinctive ecosystem. Mangrove roots grow into the water from ledges and crevices in the limestone, providing habitat for small fish and crabs. Kingfishers and herons are commonly seen perched on the rock walls or hunting in the shallow margins. Occasionally, monitor lizards are spotted on the ledges above the waterline. The atmosphere inside the hongs is quiet and contemplative — a natural environment that rewards attentive observers.
What to Expect at Hong Island
The Approach and Transfer to Sea Canoes
From the speedboat, Hong Island appears as a steep limestone karst covered in dense vegetation. The cave entrances are not obvious from a distance, adding to the sense of discovery. At a calm anchorage nearby, guests transfer into sea canoes with assistance from the crew. Life jackets are provided, and guides give a short briefing before entering the caves.
Through the Cave Passages
The cave tunnels vary in height depending on the tide, and at times guests may need to lean back slightly as the canoe passes through. The experienced guides handle this smoothly, allowing guests to enjoy the quiet atmosphere created by dripping water, birds overhead, and the gentle movement of the canoe.
Inside the Hong
The caves open into a hidden lagoon surrounded by tall limestone cliffs. The water is calm, and natural light filters down from above, creating a peaceful and unique setting. Guests have time to take in the scenery before the guides paddle back through the cave and continue the journey through Phang Nga Bay.
Activities and Experiences at Hong Island
Hong Island’s primary experience is sea canoeing through the cave passages and into the inner lagoons. This connects directly to Simba’s kayaking experience, which forms an important part of the Phang Nga Bay tour itinerary. Wildlife observation — birds, fish, and occasional monitor lizards — is a natural part of the experience, connecting to the wildlife and animals element of Simba’s broader experiences offering. Photography inside the hongs is a popular activity, and guides are patient and helpful about positioning and timing. The stop at Hong Island is typically paired with a visit to Panak Island, which offers a different but complementary caving character.
How We Visit Hong Island on Our Phang Nga Bay Tour
Hong Island is a regular stop on Simba Sea Trips’ Phang Nga Bay tour, typically visited as part of the sea canoeing section of the day alongside nearby Panak Island. Sea canoes are stable and guided by experienced local paddlers, and life jackets are worn throughout. The group size — capped at 18 guests — means that the experience never feels rushed or overcrowded, and the cave passages remain calm and unhurried rather than a queue-based shuffle through the rock.
Simba’s crew and guides approach Hong Island with genuine care for the environment. Canoes do not disturb the cave walls, and guides are attentive to the wildlife inside the hongs. This commitment to low-impact visiting means the experience feels as natural as it is extraordinary.
Hong Island is available on both Simba’s join-in Phang Nga Bay tours and private Phang Nga Bay charters, where groups can spend additional time in the hongs if conditions and tides allow.
Best Time to Visit Hong Island
Tidal conditions are an important factor in the Hong Island experience. The cave entrances are only accessible within certain tidal windows, and Simba's guides and crew always plan the visit to coincide with appropriate conditions. This is one of the reasons that local expertise matters on a Phang Nga Bay tour — understanding the tides and adjusting the itinerary accordingly is something that comes only with genuine experience of the bay.
Seasonal Overview
High season (roughly November to April)
High season typically offers calmer seas and clearer conditions overall.
Low season (roughly May to October)
Low season visits are still very much possible, and the bay's generally sheltered character means that cave canoeing at Hong Island can be enjoyed even when conditions elsewhere are more variable.
Simba monitors conditions closely and will always adjust the itinerary if a particular stop cannot be safely accessed.
