When I reached the big room of Carlsbad Caverns National Park, my jaw dropped immediately after saw this subterranean wonderland. After visited many great World Heritage Site caves, visiting Carlsbad was still quite interesting for me. There are two things that really shrined out from this site. The first thing is the exceptionally good management. The cave is very convenient and easily accessible to reach by elevator from visitor centre, good pathways and lovely underground toilet! Carlsbad Caverns is probably the best cave I have seen in terms of tourist facilities; also the light display did very good job, not too bright and able to highlight the unique feature of those dripstones.

The second is the stalactites and stalagmites inside the cave. The size and types of these geological wonders are truly impressive. I never saw many gigantic stalagmites like the ones in the Hall of the Giants. The ceiling is also really full of stalactites like very big yogi's bed, an unbelievable sight. The small chamber called Dolls Theatre is really fantastic; the huge amount of stalactites reminded me the beautiful foyer of wisterias. The crystal spring dome is another favourite, the white rock the always has water comes out, very mysterious and I felt like I saw the source of life directly from Mother Nature.

There are many interesting features inside the cave, although most of rock formations I already have seen before in many UNESCO listed caves, but the superlative size of stalactites and stalagmites of Carlsbad Cavern are unbelievable, and seem that almost all types and styles of dripstones could be seen in only one place which is truly amazing. In my opinion, Carlsbad Cavern is a really great World Heritage Site, one of the best representations of limestone chamber and dripstone wonders, highly recommended to visit this subterranean wonders in the corner of New Mexico.
