This is a part of the Death Railway that was constructed during the Second World War using POW labor to cut through the mountain. The site is located in a thick forest near Km. 66 of the Sai Yok-Thong Pha Phum Road (Highway No. 323). Along a 4-kilometer walking trail made by the Allied prisoners visitors can envision the difficulties faced in constructing the Death Railway using simple tools. The pass is approximately 500 meters long and 26 meters deep. In 1943 Australian POWs employing hand drills, picks and shovels, baskets and dynamite completed it within six weeks.
There is also a museum displaying contemporary photographs, maps, models, illustrations, etc. from the period. Open daily from 9 a.m. to 4 p.m. Admission is free. Call 08 1814 7564, 08 1754 2098, 0 3453 1347, Fax. 0 3453 1347, for further information.
