It looks like only a little tourist attraction from the road BUT it is a really large cave complex. The guide (Victoria) told us all about the history of the cave, the current knowledge of its formation and geology, and the planned scientific studies to be done by archeologists and geologists. We definitely recommend to visit this cave. Its a little more expensive than the nearby Areni-1 cave but it is more than worth it! A bonus: it’s super cool inside as there is a “natural airconditioning”, especially lovely on hot August days.
