A small museum in a Ice Age cave. Admission is only possible with a guided tour. Tours last about an hour and focus on Ice Age animals and cavemen. Usually on the hour; check the website beforehand. Everything is presented in Spanish, but brief summaries are also given in English if there are several foreign guests. The guide is very engaging. Adults €5, children €3 (05/25).
