Koh Tub is located within Hat Noppharat Thara–Mu Ko Phi Phi National Park, one of Krabi's most captivating natural attractions. It is well known for the “Talay Waek” (Separated Sea) phenomenon, where the tide recedes and reveals a sandbar that connects Koh Tub with Koh Mor and Chicken Island. This magical occurrence allows visitors to walk across the sea from one island to another.

The island is surrounded by crystal-clear turquoise waters, teeming with colorful coral reefs and tropical fish—perfect for snorkeling and underwater exploration. The peaceful, powdery white beach provides a tranquil retreat for visitors looking to escape the crowds and immerse themselves in nature.

The best time to visit Koh Tub is between December and early May, when the weather is most favorable and the sea is calm. During this peak season, the white sand stretches beautifully across the three islands, making the scenery truly breathtaking. This natural wonder is considered one of the most iconic Unseen Thailand destinations and is a must-visit when in Krabi.

You’ll find longtail boats and day tours readily available from Ao Nang Beach or Krabi Town, making access to Koh Tub easy and flexible.
