Huge cave with river and jungles in it, Vietnam

Maybe there really IS a Hollow Earth? This magnificent hidden forest/jungle complete with rivers, beaches, and all the greenery you could ever want is deep inside an 87 mile long cave in the Vietnamese mountains. A river has worked its way under a mountain, carving skylights and valleys as it went through the rock inside the mountain.

The cave was discovered by a farmer, and has since been explored by many people. The camping tour is about a week long and you will actually be trekking through the cave during the day and camping along the river at night. The views here are spectacular, and it just makes you think that we have discovered a new "Garden of Eden", lost for eons, here in this immense cave.

When you check out the link; be sure to watch the video at the bottom of the page. It is a fly-through of the cave with pictures that were taken by a drone, and they are just amazing! I would love to be able to see the inside of this hidden world.

@campforums , from what I read, it is almost its own little world down there. Apparently there are places where the top of the mountains have caved in over the centuries, so now the sunlight can shine in, it would get some rain probably; and birds and other flying creatures could fly in and out where it is open at the top. Animals would have come in through one of the side caves, probably.

If it didn't get enough natural sunlight, it could never be so luxuriant and green down there. I think it explains it all on the webpage somewhere.
