Anyone who knows Phuket knows the crowds: Bangla Road, overloaded piers, tourist buses and souvenir shops on every corner. Koh Yao Yai Phuket is the exact opposite. The island – roughly 137 square kilometres in size, home to around 5,000 people who live mostly from fishing and rice farming – has kept its original character entirely intact.
On Koh Yao Yai, tourists share the road with water buffalo, motorbike vendors and schoolchildren on their way to class. Small mosques define the townscape of the predominantly Muslim population. The few accommodation options that exist are family-run eco-lodges – no international hotel chains, no pool party operation. Visitors looking for Thailand that hasn't yet been polished for tourists will find it here.
Phuket's famous beaches are beautiful – but you share them with hundreds of other holidaymakers. On Koh Yao Yai, long stretches of white sand and turquoise water are often yours alone. No jet ski noise, no beach vendors – just the sound of the waves, birdsong and the scent of tropical vegetation. No overstatement: this is the everyday reality of this island.
There are beaches, and then there is Laem Haad Beach on Koh Yao Noi. This is one you need to see to understand – because no photo fully captures the experience.
At low tide, a narrow, elongated sand causeway emerges on Koh Yao Noi, extending far out into the turquoise sea – with water on both sides, open sky above, and the limestone peaks of Phang Nga Bay on the horizon. You can walk along this sandbar until the sea reaches knee-height on both sides. As the tide rises, the causeway slowly disappears back beneath the surface. This natural phenomenon is unique in Thailand – which is exactly what makes it one of the most memorable moments possible anywhere around Phuket. No built jetty, no crowds, no entrance fee: pure nature.
The Koh Yao Yai speedboat tour from Phuket is not a simple island visit – it is a carefully structured journey through some of the least visited and most beautiful corners of the Andaman Sea. Here are all stops in detail:
Hong Island (Thai: "room" or "cave") is a small island paradise near Koh Yao Yai with a remarkable feature: inside the island lies a hidden lagoon enclosed entirely by rock walls, accessible only through a narrow cave passage by kayak or snorkeling. The turquoise water of the lagoon, the vertical limestone walls and the filtered light create an atmosphere that leaves visitors consistently speechless.
For the active: an optional 490-step climb to the island's highest point. The ascent takes approximately 20–30 minutes and rewards with a panoramic view across the entire Phang Nga Bay – its distinctive limestone towers, turquoise water and, on a clear day, a horizon without end. One of the finest viewpoints in all of southern Thailand. Note: The climb is optional and can be physically demanding – sturdy footwear is recommended.
Pileh Lagoon is one of those places where visitors stare into the water in disbelief: they have simply never seen a green quite like this. The lagoon, completely enclosed by vertical limestone cliffs, catches light in a way that makes the water glow in a surreal emerald shade – even in overcast conditions. The boat anchors here, snorkeling gear goes on and everyone enters the water: coral formations, tropical fish and exceptional water clarity make Pileh Lagoon one of the best snorkeling stops on the entire tour.
Lao Lading Island is part of the Hong Island archipelago and offers two idyllic sandy coves with shade under pandanus palms. Lunch is served at Klong Hia Pier – fresh Thai dishes, seafood and soft drinks with a direct view of the turquoise water. Free time after lunch is ideal for a final snorkeling session, a quiet beach walk or simply doing nothing at all – the thing that’s hardest to manage on a typical Phuket holiday.
Koh Yao Noi, the smaller sister island, is quieter, greener and even more unspoiled than Koh Yao Yai. This is where Laem Haad Beach is located – the tidal sandbar described in full in the section above. Beyond the sandbar, Koh Yao Noi offers narrow roads through jungle and rice paddies, small cafés overlooking the bay, and a local population that welcomes visitors warmly and without performative tourism.
The final stop on Koh Yao Yai itself gives you time to simply breathe in the atmosphere of this extraordinary island: quiet beach sections with clear water, fishing boats rocking gently in the harbour and the unhurried pace of daily life in a traditional village. Those who want to explore can rent a moped briefly; those who prefer to rest will find the quiet here that they searched for in vain on Phuket.
The most common question before booking – answered clearly and honestly:
Koh Yao Yai is the larger of the two islands (approx. 137 km²) with several kilometres of beach, traditional fishing villages, rice fields and a small selection of family-run eco-resorts. Ideal for anyone who wants to explore an entire island – by scooter, on foot, or by boat. The pace is slow, the atmosphere relaxed, the nature untouched.
Koh Yao Noi is smaller (approx. 30 km²), even more peaceful, and famous for the unique Laem Haad tidal sandbar. The island also has a small but active creative scene for its size – a handful of cafés and galleries run by long-stay travellers. Ideal as a retreat for couples and anyone who genuinely wants to disconnect.
Our tour visits both islands in a single day – plus Hong Island, Pileh Lagoon and Lao Lading. The best of both worlds.
The waters and forests around Koh Yao Yai are biologically extraordinarily rich – and almost entirely undisturbed by tourist activity. What you can experience:
The reefs at Pileh Lagoon and Lao Lading Island shelter an exceptional diversity: colourful coral structures, parrotfish, pufferfish, clownfish and – in calm conditions – sea turtles. Underwater visibility is particularly strong in the dry season (November to April).
On Koh Yao Yai, visitors share the island with black kites (visible daily circling the harbour), flying foxes in the mangrove forest and the ever-present water buffalo on the rice paddies. A wildlife experience that elsewhere only exists in rarely visited national parks.
Our verdict: Koh Yao Yai is the better choice for anyone who wants something genuinely different…
from Phuket's standard island tours. Phi Phi delivers better-known scenery and a more social atmosphere. Both can be visited on separate days – they complement each other perfectly.
The ideal time for all Koh Yao Yai tours from Phuket: calm sea, clear water in Pileh Lagoon, pleasant temperatures and the best conditions for the Hong Island viewpoint climb. The Laem Haad Beach sandbar shows itself at its most spectacular during these months' low-tide phases. High season December to March – book early.
In the rainy season the sea can be rougher and tours may be adjusted at short notice. Because the Koh Yao islands are further from Phuket than Coral Island or the Khai Islands, tours are more weather-dependent. Lower prices and an exceptionally quiet island atmosphere can still make low-season visits worthwhile – on request.
Koh Yao Yai – larger (137 km²), multiple beach stretches, traditional fishing villages, rice paddies, eco-resorts. Koh Yao Noi – smaller, quieter, famous for the Laem Haad tidal sandbar. Our tour visits both islands in a single day.
A natural sand causeway on Koh Yao Noi that emerges at low tide, extending far into the turquoise sea with water on both sides – a phenomenon unique in Thailand. Our guide plans arrival timing from the daily tidal schedule.

For those who want to build on the Koh Yao snorkeling experience: the Similan Islands are considered one of the world's premier dive destinations. Seasonal access November to April only.
