Koh Klum is a historically and naturally significant island located to the south of Koh Chang. Despite being one of the largest islands in the archipelago, it remains extraordinarily quiet and offers high privacy, as it lacks the dense settlements found on the main island. The landscape is dominated by rugged stone mountains interspersed with mangrove forests and small, scattered beaches. This makes it a premier destination for travelers looking to avoid the congestion of mainstream tourist spots and experience nature in its most unadulterated form.

The unique identity that captures the hearts of travelers is the diverse range of water activities, particularly its status as a strategic hub for fishing and squid jigging, which is highly acclaimed among local fishers and adventurous tourists. Additionally, the island's perimeter features shallow snorkeling spots with coral reefs and underwater rock shrines that serve as habitats for numerous fish species. The surrounding waters are exceptionally clear with a vibrant turquoise hue that contrasts beautifully with the lush green canopy, reflecting a flourishing marine ecosystem.

The atmosphere on Koh Klum provides an intensely peaceful and relaxing experience. Most visitors prefer to charter a long-tail boat for a one-day trip to sit by the silent shores or explore the strangely shaped rock formations carved by sea erosion over centuries. During low tide, wide sandy stretches are revealed, perfect for strolling and absorbing the sea breeze without the interruption of engines or large crowds. This island acts as a natural therapy space for the soul, providing a much-needed break from the modern world.

For peace-seeking travelers and artists, Koh Klum serves as a magnificent source of inspiration amidst the endless horizon. Meanwhile, groups of friends or families often choose this island as a picturesque lunch spot on a boat or a simple yet special picnic on the beach. The striking stone cliffs that stand majestically against the sea also provide a cinematic backdrop for photography that is hard to find on neighboring islands, making every snapshot a piece of art.

If you are searching for a place where you can fully immerse yourself in the sound of waves and the ocean breeze, Koh Klum is the answer you cannot overlook. The simple yet mysterious beauty of this island will make you feel as if you have traveled back in time to the early days of Koh Chang when everything was still pure. It is a life-enriching travel experience that will make your visit to Trat truly complete and unforgettable.

Travel Tips

• Best Visiting Season: Visit during the peak season from November to April when the sea is calmest and the water is at its clearest.

• Preparation: Since Koh Klum is highly natural with minimal facilities, visitors should bring their own drinking water, snacks, and basic first-aid kits.

• Fishing Activities: If you wish to go fishing, it is recommended to contact a local boat captain (Tai Ruea) in advance, as they know the best spots and the right tides.

• Conservation: Please help keep the island clean. Do not leave trash behind, and avoid touching the coral reefs while snorkeling.

• Planning: Always check the weather forecast before traveling, as strong winds can make the boat ride to certain parts of the island risky.
