Kra Sae Cave, a historical cave associated with World War II, is located near a perilous section of the railway construction site. Believed to be a dangerous spot, it was rumored that the Japanese army used the cave as a storage and sleeping area to evade bombings. Folklore also tells of a legendary giant snake during the war.
Today, Kra Sae Cave, though small, is a place of reverence. Visitors can pay respects to the revered monk's statue inside. The area is known for the Death Railway scenic viewpoint, a 400-meter trail along the cliff offering breathtaking views of the Kwai Noi River. Travelers worldwide consider it a must-visit. Additionally, local products are available for purchase, providing a diverse shopping experience.
