Many steps down to the cave but it's worth it, and beautiful view. We were ther in the beginning of April and we practically got a self guided tour. It's a very big cave and beautiful rooms. A must to visit this cave. It's warm inside so don't take extra sweater with you as we did.

Definetly one of the things you must visit if you go to Alghero- Sardinia. 656 stairs.. (15 min going down.. some 25 going up). breath taking views... you can take magnificant photos. we didn't take the visit to the cave itself. There is a possibility to come with the bus from Alghero, but we rented a car and came with... More

Sometimes it's hard to find the words to describe something so incredibly beautiful. I guess wow will have to do. Nature is as good if not better than any architect. This truly remarkable place has to be seen if you are in the Alghero area.

The cave is stunning. The walk down the stairs, which drops around the side of the cliffs, affords an amazing view and isn't quite as tough as the guidebooks make out. Unfortunately, as is often the case in Italy, the small details have been very poorly thought through. You are frogmarched around the cave as part of an overly big... More

This cave is one of the oldest places on planet earth- its is millions of years old, in fact dinosaurs roamed the earth when it was formed. Interestingly the sea has nothing to do with its formation- I will leave the guide to fill you in on how it was made. Its worth a visit adults and children alike- I... More

Well worth climbing the 645Stairs after visiting this Natural wonder ! But make sure you can do this kind of exercise, you can always take the boat trip, from Alghero to the Grotta! Beautiful Place!

Fantastic caves and rock formations. You can either travel by car along the cliffs and climb down a cliff path (and back up again!) or catch a boat Alghero harbour. The whole trip takes about 3 hours. When you purchase your boat ticket, note that the fee for entering the caves is not included. Also, if the weather is a... More

This was a great day out. The kids enjoyed the boat ride over to the caverns and also the cavern itself. I'd definitely recommend taking this trip.

Great cave but I love caves (and I've seen better ones and worse). Here I actually liked the many stairs you have to take to get there. It makes it kind of more interesting. We went there mid September and it was not too busy. But you probably should go as early as you can just in case... We took... More
