Frasassi Caves Italy or Grotte di Frasassi, are one of the Italy’s top caverns and it is well worth a visit. One of the largest known cave systems in Europe, it’s located in the municipality of Genga, in the province of Ancona, Le Marche. First discovered in 1971, the massive cave system wasn’t opened to the public until 1974. The caverns are open all year long and guided tours are offered to visitors.

If you are visiting Le Marche, it is a surprising and fascinating place to see. Breathtaking stalagmites and stalactites are scattered throughout the massive caverns that have abundant water. The Ancona Abyss with its vaulted 200m ceilings is one of the most popular spots on the tour.
