My tip“Entry is free; the climb is up steep steps. Park near the museum, not where the navigation app leads you.”
A small Almohad fortress carefully restored on a rock above the old town, with cave houses around it; an example of the village forts that guarded the Vinalopó valley.
Easy to reach
In Petrer (buses from Alicante); a steep staircase climb of 5–10 minutes from the old town. Sat navs may lead you astray, so park near the museum.
Address
Carrer Coves del Castell, Petrer
