Though Italy is famous for a great many of things, one famous attribute that you are less likely to have heard of or associate with the country is its incredible number of caves. In fact, it is one of the countries that has the most caves in the entire world – more than 35,000 in number – and, among them, the largest tourist cave on Earth: the Grotta Gigante. Officially recognised by the Guinness Book of World Records, the main underground chamber of the Grotta Gigante measures 98.5m in height, 76.30m in width and is 167.6m long.
Located near Borgo Grotta Gigante, in the municipality of Sgonico in the lesser-known Italian region of
Friuli Venezia Giulia, it has been a popular tourist attraction since it opened to the public in 1908. Seeming like something plucked from the beautifully illustrated pages of a fantasy novel, it makes for an extraordinary sight. Just find a
vacation rental in Friuli Venezia Giulia and set a day aside to go explore this underworld kingdom.
