Italy: Frasassi Caves
Frasassi Caves are considered the most impressive limestone caves in Italy, with mega massive chambers filled with formations that are still growing and wet. The caves were only discovered in 1971 by accident and have been explored since with more and more passages being found. The caves are deep underneath the mountain and are very wet with water dripping everywhere. There are stalagmites standing 5m tall here and some stalagmites hanging 7m long from the ceiling. Having seen a lot of caves all around the world, Frasassi is definitely impressive, but quite commercial with the need to take a bus to get to entrance, tightly controlled tour groups, guides yapping about how formations resemble elephants and bears (I hate that gibberish) and limited photography in the best halls since they are trying to make you pay for “official” photos.
