Sierra de las Casas
Lonely Planet review for Sierra de las Casas
It's possible to climb to this distinctively shaped hill from the west end of Calle 22. A few hundred meters along a dirt track, you will see a trail on the left toward the hills. At the very foot of the hill is a deep cave with a concrete stairway leading down to the local swimming hole. A trail beyond this leads to the mountaintop, from where you can see most of the north of the island.
