Thailand
Floating in the emerald waters of Phang Nga Bay between Phuket and Krabi, Ko Yao Yai is the larger and quieter of the two Yao islands — a place where rubber plantations shade the interior roads, Muslim fishing villages line the eastern shore, and the pace of life moves at a rhythm wholly disconnected from the tourism juggernaut just across the water. While Phuket's western beaches draw millions of visitors annually, Ko Yao Yai remains an island of unhurried authenticity that rewards travelers willing to venture slightly off the beaten path.
The island's coastline alternates between mangrove-fringed inlets and long stretches of sand backed by coconut palms and casuarina trees. Loh Paret Beach, on the northeastern shore, offers views across the bay to the extraordinary limestone karsts that have made Phang Nga Bay one of Southeast Asia's most iconic landscapes — those same towering formations, draped in tropical vegetation and rising vertically from jade-colored water, that featured in the James Bond film The Man with the Golden Gun. At low tide, the beach extends hundreds of meters, revealing tidal pools teeming with small crabs, sea cucumbers, and juvenile fish.
Life on Ko Yao Yai centers around its fishing villages, where the population — predominantly Thai Muslim — maintains traditions of boat-building, net-making, and communal fishing that have defined these communities for generations. The morning markets in the village centers offer fresh-caught seafood, tropical fruits, and local snacks prepared by village women. The cuisine reflects the island's Muslim heritage and coastal location: fragrant fish curries enriched with fresh turmeric and lemongrass, grilled squid brushed with tamarind sauce, and the ubiquitous roti served with condensed milk or curry dipping sauce.
The waters surrounding Ko Yao Yai offer exceptional kayaking and snorkeling opportunities. Sea kayaking through the bay's limestone caves and hongs — collapsed cave systems that create hidden lagoons accessible only through narrow passages — is a magical experience, particularly at dawn before the day-trip boats arrive from Phuket. The coral reefs off the island's southern tip support healthy populations of reef fish, and the calm, shallow waters make snorkeling accessible even to beginners.
Expedition cruise ships and smaller vessels anchor off Ko Yao Yai's beaches and tender passengers to shore. The island has no deep-water port, which helps preserve its tranquil character. The best visiting conditions occur during the dry season from November through April, when skies are clear, seas calm, and humidity more manageable. The southwest monsoon from May through October brings rain and rougher seas, though the island remains visitable and the lush green that follows the rains gives the landscape a particular tropical beauty.
