A group of around 20 of us visited on a Saturday. It was super crowded with large groups of domestic chinese tourists. The outside is pretty enough but entering the cave is rather stressful because of the crowds. It does not seem to be a very big cave and many parts have been modified to cater for tourists. Many coloured lights all over and there seems to be a lot of canals inside. There were some interesting sections but because of the crowds, we felt rather rushed. The atmosphere felt rather humid. Overall , it was an ok experience but i have visited more spectacular caves that were less modified
