Villa Jovis, Capri

Beautiful ruins of a very interesting villa. Some parts were closed, however, there was still plenty to see. The views from up there are also great. The walk there is not very long, and despite it being uphill, it's not that strenuous. There's also a restaurant with great views on the way if you need a rest and/or a drink and food. Also along the way there is a park with even more spectacular views of the sea, cliffs, and the island.

This is an incredible place, and absolutely worth the hike. The views are incredible and you get to walk right inside the ruins. Definitely a once in a lifetime opportunity. However, be aware that the entry fee is 6€ and CASH ONLY so make sure you get some cash before you hike all the way up, since there's really no other places nearby to get cash once you leave the main square.
