The Pristine White Sand of Koh Kram Noi. From this aerial view, the brilliant white sand beach stretches beautifully against the deep indigo sea. The sand here is incredibly white and pure, preserved by the lack of tourism and permanent structures. This pristine shoreline is not only stunning to look at but also serves as a vital, safe nesting site for sea turtles, making it one of the most untouched and peaceful coastal landscapes in the Gulf of Thailand.
