Lod Cave (often referred to in the Thai language as Tham Lod) is a large spectacular natural limestone cave system, its main feature being the stream which runs through the heart of the cave. The best way to see the caves is to hire the services of one of the guides at the cave office. Here you have a choice of exploring some of the dark caverns by lamplight and/or taking a bamboo raft into the cave. Bats are in abundance here as well as many swifts which make their nest in the mouths of the caves both can be seen exiting the caves at dusk in large numbers. There is no artificial lighting in the cave so any exploration should be done with the services of a guide with lamps. A number of prehistoric wood coffins have been found in this cave, the remnants of the coffins can still be seen in the cave
