Chong Lat island, or simply "Chong Lat," is a unique maritime geographical feature located within the Than Bok Khorani National Park in the Ao Luek Tai Sub-district of Krabi. Its defining characteristic is a narrow sea passage sandwiched between "Koh Chong Lat Nuea" (North) and "Koh Chong Lat Tai" (South). This channel has served as a vital strategic route for local mariners since ancient times, acting as a natural breakwater that shields the interior from the powerful winds and waves of the Andaman Sea. Consequently, the water surface within the strait remains incredibly calm and mirror-like, earning it the nickname "The Mirror of Ao Luek," perfectly reflecting the majestic limestone karsts that loom on either side.

Geologically, Koh Chong Lat is characterized by steep, towering limestone cliffs that are part of the broader karst system spanning Phang Nga Bay and Krabi. Along the aquatic cavern walls and cliffs, significant historical evidence can be found in the form of ancient rock art. These prehistoric paintings, estimated to be thousands of years old, indicate that the area was a hub for early human activity. Furthermore, the entire coastline along the strait is enveloped in a flourishing mangrove ecosystem. This pristine habitat serves as a crucial nursery for marine life and a sanctuary for various bird species, allowing eco-tourists to experience rich biodiversity firsthand while kayaking through the tranquil waters.

Beyond its natural beauty, Koh Chong Lat is central to the traditional way of life for the local fishing communities of Laem Sak and Bor Thor. It is common to see local long-tail boats gliding through the channel as fishermen set crab traps or cast nets using methods passed down through generations. The true magic of the area reveals itself when the tide is still; the emerald water transforms into a vast glass floor, creating a surreal experience of floating through a silent, prehistoric landscape. It stands as a premier eco-tourism destination, prioritizing high-quality relaxation and authentic environmental education away from the crowded tourist hubs.
