Rovinia cave has an entrance of 6 metres wide. The cave is 17 metres deep and 15 metres high. On the right side of the cave
there is a possibility to climb upwards. The last part of the climb follows a primitive ladder. Once outside the cave, a path leads to the Hole of Ha.
The Hole of Ha is in fact a collapsed area of soil. Beneath the water surface there is a 25
metres long sea cave. The Hole of Ha is almost at the end of this sea cave.
