Hidden Lagoons & Caves
Through Panak's collapsed cave systems and into Hong Island's enclosed lagoon. Slow, quiet water. The kind of stop where you stop talking.

Long-tail boats, run by captains who grew up on this water — ten years of working alongside them on Phang Nga Bay.
We design days around tide, season, and light. Every day shaped to your group.
Pick the moments that matter to you.
Every day combines two to four of these; Snorkelling is a trip of its own. Choose what matters most — we design the order around tide and light.

View gallery →Slow exploration of the bay's quieter reaches — limestone cliffs, hidden coves, shallow lagoons, and the floating villages most tours pass by.
View gallery →A small private beach with shade for snacks. Sandbar swims, calm water, the kind of pace where guests stop checking the time.
View gallery →A monkey-island stop — fed and watched at safe distance, with the captain on hand. Brief but memorable; we don't linger.
View gallery →Swim stops over shallow reefs around the small islands off Phuket's east coast — Koh Naka Noi, Koh Li Pe, Koh Khai Nok, Coconut Island, Koh Khai Nai, Koh Rang Yai and Koh Pae. Clownfish, giant clams, schools of small fish; we go where the water is clearest.

Plan your day →At Hidden Horizons, we believe the most memorable journeys begin with genuine encounters. Our captains are children of the sea, born and raised on the islands and in the villages of beautiful Phang Nga Bay. They love where they come from, and they enjoy sharing what they know: their stories, and the remarkable landscapes that have made this unique part of Thailand famous.
Long-tail captain · Koh Panyi
Born on the island of Koh Panyi, Khun Him grew up to the rhythm of the tides and the life of the local fishing community. From a young age he went out to sea with his family, and came to know Phang Nga Bay deeply. He loves fishing and the region's dramatic karst formations, and enjoys showing his guests the bay's most beautiful hidden places. His calm, his kindness and the attention he gives every passenger make him a much-loved captain.
Long-tail captain · Koh Yao Noi
From Koh Yao Noi, Khun Chok knows every corner of the bay like the back of his hand. Raised in a seafaring, fishing family, he has spent his life exploring the lagoons, secret beaches and majestic cliffs around his island. Always smiling and attentive to what his guests need, he loves passing on his passion for the sea and for the unique karst landscapes of Phang Nga Bay.
Long-tail captain · Koh Yao Yai
From Koh Yao Yai, Khun Souleman is a true lover of nature and life at sea. Fishing has been part of his daily life since childhood, and has given him an excellent knowledge of the local waters. Proud of where he comes from, he loves showing visitors the limestone cliffs, hidden lagoons and exceptional views of Phang Nga Bay. His kindness, professionalism and sense of hospitality make for a memorable day on board.
Hidden Horizons started in 2016 with one long-tail boat and one captain, who'd been fishing Phang Nga for years before he took his first guests out. We didn't set out to build a tour company. We set out to share the bay the way the people who live on it know it.
Today we work with three captains — all from villages on or near the bay — and the same one boat we still maintain by hand. We don't run a fleet. We don't sell packages. We design days, tide by tide, and we send guests home with stories about the people who took them out, not just the places they saw.
A traditional Thai long-tail, quietly upgraded for a day on the water.
The prow, traditional and patient, with the small offering our captains never skip.
Wide canopy, full shade — even inside the sea caves.
Cushions, cold drinks, fresh fruit through the day.
An absolutely magical day! We explored secret beaches you can only reach by boat, went through natural caves that open onto beautiful hidden lagoons, and discovered incredible landscapes far from the crowds. The children loved the adventure and swimming in the crystal-clear water. An authentic, unforgettable experience.
Hidden Horizons showed us another side of Phuket and Phang Nga Bay. Sailing through sea caves into hidden lagoons was an exceptional moment. The deserted beaches, the majestic cliffs and the calm of the place made us feel we were alone in the world. A perfectly organised trip that we recommend without hesitation.
An incredible adventure from start to finish! We explored secret coves, went through spectacular caves that open onto hidden lagoons surrounded by limestone cliffs, and enjoyed paradise beaches far from the tourist trail. The team knows the region's hidden treasures inside out. Probably one of the best experiences we've had in Thailand!
Yes — and most guests do. All the moments can be combined, and usually are: a typical day strings together two to four of them, in the order the tide and light allow. The one exception is Snorkelling — it's a separate trip. A quiet beach and time with the wildlife fit into either trip, but the lagoons, James Bond Island and Phang Nga Discovery don't combine with snorkelling. Want both? We'll plan snorkelling as a day of its own.
Up to 10 people per boat — no more than six adults, with children making up the rest. Bigger groups take two or more boats, travelling together. Always private — your group only, never combined with others.
Hotel pickup, fuel, captain, an EN / FR / TH guide, fresh local food, fresh fruit, cold drinks, snacks, cushions, shade, life jackets, first-aid. National park fees (Phang Nga Bay, Hong Islands) are quoted at booking — they vary by route and group size, so we don't bury them in the headline price.
We watch the bay the morning of every trip. If the captain calls it off for safety, we reschedule for any day in your stay or refund in full. If you cancel for non-weather reasons, we ask 48 hours' notice for a full refund; less than 48 hours we hold half the deposit against a future trip.
Yes. We route around the youngest and the oldest in the group — calm-water moments, shaded beaches, kid-friendly stops, paced for grandparents. Tell us the ages in the brief and we'll design accordingly.
Tide and light dictate most of it. Caves and lagoons want low tide; James Bond wants early light. We talk through your group's energy — kids, grandparents, swimmers, photographers — and we send a draft itinerary the day before. On the boat we adjust live.
We'll tell you the day we confirm — usually one of our three captains, all locals from villages on or near the bay. If a particular captain matters to you, mention it in the enquiry; we'll work it out.
Build your day below — the estimate updates as you go. We'll come back within 24 hours, often sooner.
