Tham Khao Bin cave is the most beautiful cave in Ratchaburi province. It is located 20 kilometres from the town along the route to Amphoe Chom Bueng and 2 kilometres along an access road. The cave extends 300 metres from the entrance and is separated into eight rooms that are easy to explore, it has impressive stalactite and stalagmite formations.
However, it may be difficult to breathe inside for some people as the cave is hot and humid. Suggest to bring some dry clothes and a small towel.
A visit to the cave is easy to combine with a private tour to the floating markets from Bangkok as those are in the same province.
