Admire the Beauty of Khao Bin Cave
Khao Bin Cave is another impressive cave to visit in Ratchaburi but unlike the other 2 caves above, this cave is in its own league when it comes to how big it is. Within Khao Bin Cave, you will find 8 massive halls all with their own unique features and different rock formations for you to explore. In each room, you will find all kinds of beautiful stalagmites and stalactites, many of which are more than a thousand years old.
The cave is well-lit with a clear walking path that goes in a loop and it will take you at least 45 minutes to complete the loop. Keep in mind that once you are inside the cave, there is no toilet or resting spots so be sure to prepare yourself before entering the cave. The cave is also extremely humid, even more so than any of the caves I have been to in Thailand and so make sure you bring a bottle of water with you when you enter. Khao Bin Cave's opening hours are between 8 AM to 4 PM every day even during COVID and the admission fee is 20 THB for both Thai and foreign adults and 10 THB for children.
