Spettacolari!!!!!!!!!!! - Amazing what nature can do over time we are talking about thousands of years, worth the trip from any point really extraordinary games.

Not to be missed! - Spectacular! The ticket price includes entry to the caves with a guide, car parking and the shuttle to the cave entrance...perfect! The visit lasts more than an hour and the spectacle of nature is displayed at 360 degrees. Perfect for children. Be careful of the wet floor, you need to wear suitable shoes and a sweatshirt because inside it is a constant 14 degrees with humidity approaching 100%.

Enchanting - It was a really nice tour where you could see things that you definitely don't see every day! Also suitable for children, it is a trip that I would recommend and do again.

Must see - One of the most beautiful caves ever visited. Listened with fascination for an hour and a half. Large free parking. Best to reserve in advance.

Crystal Lakes, Niagara Falls & The Hall of Candles - These 190 million years old caves are a magical underground world. I had no idea they would be so beautiful or that they would be so extensive and they were an unexpected highlight of our stay in the Marche area. The caves system extends nearly 30km with crystal lakes, tunnels, towering stalagmites and hanging stalactites as big as church organs. The largest stalagmites, ‘the Giants’, are more than 20m long and the largest cave is big enough to fit the entire Milan Duomo inside and tall enough to stack two Big Bens on top of each other. There are formations with names like Niagara Falls, the Camel, Hall of Candles, the Madonna, the Polar Bear and the Sword of Damocles which gives you an idea of the variety and size of the formations. It’s a big day out and there are some practical points which are good to know in advance. These are: * You will need a car. It would be very difficult visit without one. There is a large carpark at the site * You can’t drive all the way and will still need to get a shuttle bus transfer to the mouth of the cave. Allow at least 20 - 30 minutes to buy your ticket and catch the bus. The buses are not very regular so you will probably have to wait for some time. We just missed one and had to wait about 40 min. Fortunately there are food stalls (surprisingly good pork rolls) and also some souvenir stalls selling T-shirts, postcards and rock samples etc. We picked up an inexpensive little book on the history of the caves. * Tickets (€18) can be pre-bought online and includes the shuttle bus and the timed tour (you can only enter the caves on a tour). We bought our tickets on the day at the site but we had to wait in a line. Id recommend buying in advance online. * There are some English tours but most are in Italian. We accidentally joined the Italian tour but the sights are so stunning, it was still worthwhile and we were probably better off doing this than waiting for ages for an English tour. * wear flat comfy shoes and take a jacket as its quite cool inside the caves and you’re on the tour for about 90 minutes. * There are some stairs but its quite manageable for kids * Two small museums are included in the ticket but we ran out of time to see them. In hindsight, we should have started earlier and made it a full day of it.

A Must Visit - We went to this attraction not expecting to be so taken back with the enormity of these underground caves and the stalactites and stalagmites are so beautiful and impressive. You need to book well in advance there are English speaking tour's but we left it too late to book the English guide tour.

Crowded but worth doing - The whole family enjoyed this experience. My 11 and 8 year old sons loved it. The caves themselves are amazing, a real wonder to see. My only comment would be that I felt they tour operator was both allowing too many people on one tour - it was impossible for everyone to hear the guide at one time - and that there were too many tours running consecutively, meaning that tours had to squeeze by each other to pass across narrow bridges etc. Obviously they are doing this to maximize income but it would be a much more serene experience in an incredible environment if there were less people in there at one time. That said, I would recommend this as a family outing - just be sure to check the times of the English tour (if that’s what you want) on the website and also take a sweater as it’s 14 degrees inside!
