Koh Luang Waterfall.

Koh Luang Waterfall is distinguished by its beautiful blue-green water, which results from the dissolution of limestone in the water. When sunlight shines and hits the water, it absorbs the red wavelengths, making the water appear blue-green and clear. Within the parking area of Koh Luang Waterfall, there are facilities including restrooms, showers, and shops, which are run by locals. They offer soft drinks, packaged snacks, papaya salad, and grilled chicken, available only during festivals.
