@springdog: Nam Lod Cave. Mae Hong Son. Thailand. Nam Lod Cave is one of the largest limestone cave systems in northern Thailand — carved by an underground river and explored by foot, ladders, and bamboo raft. Located near Pai in Mae Hong Son province, the cave stretches over a kilometre and contains prehistoric paintings, ancient teakwood coffins, and three massive chambers shaped over millions of years. Entry requires a local guide and lantern, making it one of the most unique cave experiences in Thailand.
