The Pozalagua cave is known for housing the largest collection of eccentric stalacticts in the world. Observing this curious phenomenon of nature is well worth a visit to the cave, considered an "underground cathedral". It is necessary to buy tickets and the visit lasts about 50 minutes. Keep in mind that it is quite cold inside the cave.

Ramales has well-preserved architecture, with some Indian mansions with beautiful gardens and gates. The Revillagigedo palace (18th century) stands out. However, its most valuable heritage is the group of caves located at the beginning of the century by Alcalde del Río: Covalanas, La Haza, Cullalvera and Sotarriza house magnificent cave paintings inside.
