Tup Island (Koh Tup) is one of Krabi’s most iconic hidden gems, nestled within the Mu Koh Poda archipelago. Famous for its stunning white sandbar called Talay Waek (Separated Sea), this tiny island offers a unique natural experience. It is where nature literally parts the waves for you during the low tides. Surrounded by crystal-clear turquoise water and soft white sand, Tup Island is one of the highlights of the popular Krabi 4 Islands tour. Visitors can swim, snorkel, walk the sandbar, and enjoy the island’s tropical scenery. Whether you're planning a romantic getaway or an island-hopping adventure, here is why Tup Island is a must-add to your Krabi itinerary.

Nestled in the Mu Koh Poda archipelago, southwest of Ao Nang, Tup Island is between Koh Poda and Koh Kai (Chicken Island). Unlike the crowded beaches of Thailand, it offers the opportunity to witness the rare and raw beauty of nature. The island is also known for its soft white sand, clear shallow water, and colourful marine life, making it perfect for swimming and snorkelling. With its unique sandbar and stunning tropical scenery, Tup Island is one of the most photogenic places to visit in Krabi.
Twice a day, as the tide recedes, the Y-shaped sandbar rises from the shallow turquoise waters, known locally as Thale Waek. It forms a walkable land bridge connecting Tup Island, Chicken Island, and Koh Mor. The island is part of Krabi's famous Four Island Tour, alongside Koh Kai (Chicken Island), Koh Poda, and Phra Nang Cave Beach. Together, these islands represent some of the finest natural scenery in Southeast Asia.

Tup Island is compact but rich in natural experiences. Here is what to expect during your visit:
One of the best things to do in Krabi is to witness Thale Waek in Tup Island. During low tide, the sandbar linking Tup Island to Chicken Island and Koh Mor fully emerges, creating a shallow, walkable strip of white sand surrounded by knee-deep, crystal-clear water.
Tip: Wear reef shoes or flip-flops when crossing the sandbar, as sharp shells and coral fragments can make the walk uncomfortable on bare feet.
The waters surrounding Koh Tup Island are rich with marine life and colourful coral reefs. Tropical fish, starfish, and sea urchins are commonly spotted close to the shore. Because the water is generally calm and shallow near the island, snorkelling here is safe and accessible even for beginners and families with young children.
Tup Island has a beautiful stretch of soft white sand ideal for sunbathing and swimming. The water is typically very clear and calm, making it one of the best swimming spots along the Krabi coast. The shallowness near the sandbar also makes it a safe swimming area for families.
Behind the ranger station on the island, a short, easy hike leads to a scenic viewpoint. From here, you can look out over the western islet, the surrounding Andaman Sea, and the profiles of Koh Poda and Koh Kai in the distance. It is a must-add activity to your Krabi tour packages during low tide.
Tup Island is part of the Four Island Tour. Most visitors combine it with stops at Chicken Island, Koh Poda, and Phra Nang Cave Beach in a single day. Each island has its own character — whether it is the dramatic limestone caves at Phra Nang, the long swimmable beaches of Koh Poda, or the playful sandbar walk at Tup.
