For many people, Koh Phi Phi is the very image of Thai paradise: limestone walls plunging straight into an unbelievably turquoise sea, hidden bays, dazzling white-sand beaches and water so clear you can see the fish from the boat. The postcard view of Maya Bay —made world-famous by the film 'The Beach', with Leonardo DiCaprio— turned this small archipelago into one of the most sought-after destinations in Southeast Asia, and you only need to approach those cliffs by boat to understand why.
But Phi Phi is also a place of contrasts. Phi Phi Don, the only inhabited island, has a split personality: on one side, its dreamy beaches and dizzying viewpoints; on the other, an intense, noisy, party-loving centre (Tonsai), with fire-show bars on the sand and music until the early hours. Neighbouring Phi Phi Leh, by contrast, is uninhabited and protected, and there, after years of tourist overuse, the authorities closed and then reopened Maya Bay under strict rules to save it from being loved to death.
This guide helps you get the most out of Phi Phi without falling into the traps of mass tourism: when to go, how to get there by ferry, which island tour is worth it, how the Maya Bay restrictions work today, where to dive and snorkel, and how to choose between the buzz of Tonsai and the calm of the more remote beaches. With the right information, Phi Phi still offers some of the most spectacular seascapes on the planet.
For centuries the Phi Phi islands were a refuge for fishermen and Malay Muslim communities, and their caves —such as Viking Cave on Phi Phi Leh— were used (and still are) to harvest the valuable swiftlet nests used to make the famous Chinese bird's nest soup. Almost entirely uninhabited until the 20th century, they began to be settled with coconut plantations and small fishing villages. Tourism arrived from the 1980s, first with backpackers, and exploded after the release in 2000 of the film 'The Beach', shot in Maya Bay, which catapulted Phi Phi to worldwide fame. The tsunami of 26 December 2004 devastated Phi Phi Don, which was almost flattened and suffered hundreds of victims, but the island was rebuilt within a few years. The full story, from the swiftlet nests to the closure of Maya Bay, is on our history page.

Origins, formation and what the sources say.
Before it became one of the most famous islands on the planet, Phi Phi was a remote, almost empty corner of the Andaman Sea. Anyone who had heard of it knew it for two things: fishing and swiftlet nests. The name 'Phi Phi' itself comes from the Malay 'api-api', the name of a type of mangrove (the black mangrove) that grew in the area; over time, Thai pronunciation turned it into 'Phi Phi'. It's a reminder that these waters belong as much to a Malay and Muslim cultural world as to Buddhist Thailand.
For centuries, the islands were visited by Muslim fishermen of Malay origin. Most of them settled on Phi Phi Don, the only one of the archipelago's six islands with enough flat land and water to live on. Uninhabited Phi Phi Leh, on the other hand, held a peculiar treasure: in its caves, such as the famous Viking Cave (Tham Phaya Nak), swiftlets build their nests. Made of hardened saliva, these nests are a very expensive delicacy in Chinese cuisine and the base of the famous 'bird's nest soup'.
Collecting the nests is risky work, done by climbing flimsy bamboo scaffolding up the cave walls. For generations it has been a very profitable business, closely controlled through family concessions. It still goes on today, which is why access to the Viking Cave is restricted. That quiet economy of fishermen and nest collectors shaped life on Phi Phi long before the first backpacker turned up with a camera.
The landscape that amazes millions of visitors today, with sheer cliffs plunging straight into the sea, took millions of years of geological history to make. Phi Phi's rock is limestone, formed on the floor of ancient tropical seas from the build-up of coral skeletons and marine organisms. Over time, tectonic movements lifted those layers of limestone, and water and weather eroded them into the spectacular shapes we call 'karst': steep walls, caves, arches and inner lagoons.
That same geology explains many of the archipelago's wonders. There are enclosed lagoons like Pileh, which you can only enter through narrow gaps in the rock, the swiftlet caves, and sheltered bays with calm, clear water. Below the surface, the coral reefs around the islands are home to extraordinary biodiversity, with reef sharks, turtles, moray eels and hundreds of species of fish.
To protect this natural heritage, Hat Noppharat Thara–Mu Ko Phi Phi National Park was created in 1983. It covers Phi Phi Leh, the archipelago's waters and reefs, and part of the Krabi coast. National park status brings entrance fees and conservation rules. In recent years it has also brought increasingly strict measures, such as the closure and regulation of Maya Bay, to try to slow the damage caused by huge tourist pressure. Ever since, the tension between conservation and exploitation has been the big underlying theme on Phi Phi.
Tourism first reached Phi Phi in a modest way in the 1980s and 1990s, brought by backpackers travelling around southern Thailand in search of cheap, idyllic beaches. The turning point came in 2000 with the release of 'The Beach', directed by Danny Boyle and starring Leonardo DiCaprio, much of which was filmed at Maya Bay on Phi Phi Leh. The film, based on Alex Garland's novel, told the story of a secret paradise that is ruined once it is discovered. Given what came next, the irony is tragic.
The shoot had already caused controversy. To 'improve' the beach for the cameras, the production altered Maya Bay's vegetation and natural dunes. Environmental groups complained and the case went to court in Thailand. But the bigger impact was the pull effect: millions of people around the world saw those images and wanted to visit 'DiCaprio's beach'. Within a few years, Phi Phi went from backpacker hideaway to global tourist phenomenon.
The result was an explosion of boats, hotels and visitors. At its worst, Maya Bay was getting thousands of people and hundreds of boats a day. Anchors were smashing the coral, and the pressure on a tiny, fragile ecosystem could not be sustained. The paradise the film had put on the map was literally dying of its own success, and by around 2018 the Thai authorities decided drastic action was needed.
On the morning of 26 December 2004, an undersea earthquake of magnitude close to 9 off the coast of Sumatra set off a devastating tsunami that crossed the Indian Ocean. Phi Phi Don's geography left it terribly exposed. The village sits on the low, narrow isthmus that joins the twin bays of Tonsai and Loh Dalum, just a few metres above sea level. When the giant waves came in from both sides at once, they wiped out almost the whole heart of the island.
The disaster killed hundreds of people on Phi Phi, both residents and foreign tourists in the middle of high season, and left the island in ruins. Along with neighbouring Phang Nga province, it was one of the worst-hit areas in all of Thailand. For weeks, the island was taken up with rescue work, identifying victims and clearing up, with a large contribution from volunteers who came from all over the world.
Rebuilding was hard but fairly quick. Within a few years Phi Phi Don was back on its feet, this time with early warning systems, signposted evacuation routes and warning towers. Tourism came back strongly, and the island returned to its pre-tragedy visitor numbers and then went beyond them. Signs and memorials still recall that day. The memory of the tsunami lives on in a community that learned, in the hardest possible way, how vulnerable its home is to the same sea that gives it life.
By 2018, the damage to Maya Bay was impossible to ignore. Marine scientists warned that most of the bay's coral had died, destroyed by boat anchors, sunscreen and thousands of feet walking on the reefs every day. In June that year, the Thai government made an unprecedented decision: close Maya Bay completely to tourism so it could recover. What was meant to be a closure of a few months lasted more than three years.
The experiment paid off visibly. With the bay left in peace, the coral began to regenerate and new colonies were replanted. Most spectacularly, blacktip reef sharks came back and repopulated its shallow waters. Maya Bay became a worldwide case study of how a coastal ecosystem can recover if it is given a break. Left alone, nature knows how to heal.
Maya Bay reopened in early 2022 under a completely new system. Boats no longer enter the bay; they moor behind it and visitors walk in along a boardwalk. Swimming inside the bay is banned, there are daily visitor caps and time limits, and the bay closes again for a couple of months every year to rest. Many see this regulated tourism model as the future that the Andaman's fragile destinations need. Today, Phi Phi captures better than anywhere else the big question facing Thai tourism: how to let people enjoy paradise without destroying it in the process.
