Cerro Arequita is a rocky hill about 8 kilometres from Villa Serrana whose distinctive profile — a long ridge with a steep drop on one side — is visible across the surrounding grasslands. The summit is reached by a well-marked trail that crosses open pasture and then climbs through scrub and rock to a viewpoint covering much of eastern Uruguay. On clear days you can see south toward Minas and east toward the coastal sierras.
The cave system in the hill's base is the main archaeological interest — it contains evidence of pre-Columbian occupation and nineteenth-century use as a bandit hideout, and the walls show Charrúa rock markings. A guide from Minas or Villa Serrana will know the cave entrances; access without a guide is technically possible but the cave is extensive enough to warrant company.
