Paradise cave is in Phong Nha , Vietnam. I’ve done a couple of caves here in New Zealand and there quite good but this was and awesome attraction in Vietnam. It was huge and the walk if I remember correctly was 2.5 km long although the cave it’s self is much longer.
The amount of different stalagmite and stalactite formations was amazing. It is well lit and the walkways wide and safe. You cannot actually walk on the ground but that doesn’t matter as you can see it all. The entrance is small but you are soon blown away by how big the cave is as you walk down towards the bottom the look back up at the height of the ceiling above.
To see a vlog on this find Russell Chaney channel photographer moves about a bit but it gives you a good idea. Other wise there is a 5 part series on or trip through Vietnam with other footage in one series starting a Ninh Bihn that you can view. A like and a subscribe would be appreciated. If you have visited Vietnam I’d highly recommend it, the scenery is amazing and its very affordable.
