At the top of a small, wooded hill. The entrance is closed with a gate. Excavated in 1963, remains dating from the Mousterian to the Azilian Periods were discovered, with the Aurignacian and Upper Magdalenian levels being particularly important.
In 1983, C.A.E.A.P. discovered a group of engravings, including a caprid viewed frontally, which can be dated to the upper Magdalenian. This appears similar to the engraving in Sima-Cueva del Risco in Matienzo (Ruiz Cobo Jesús et al, 2008, p96). The same group also found a small fragment of prehistoric pottery.
The whole of Cueva del Otero (Echegaray et al, 1966) is devoted to
page at University of Cantabria.
Ruiz Cobo Jesús and Muñoz Fernández Emilio et al, 2009 has a comprehensive summary of the deposits with drawings throughout the text.
