Koh Si Chang people like to call this area "Lear Koh". It is a beautiful sunset spot. And there is a beach with round stones caused during the months of March - September of every year, there will be winds blowing from the west to the east. Villagers call it "Lam Nok", making the rocks on the west side have a smooth and round surface. Hence the origin of the name of the beach as "Hat Hin Klom". At Hellfire Pass, there is also a pavilion of King Rama V who used it as a observatory.
