The Museum of Natural History — also known as the Museum of the Californias — is a small but earnest institution in the old town centre, housed in the building that served as Cabo's first elementary school in 1952. Its exhibits cover palaeobotany, geology, marine biodiversity, astronomy, and anthropology, with particular attention to the Pericú and Cochimí peoples who inhabited the Baja peninsula before Spanish colonisation.
The collection includes skeletal remains of local marine mammals, birds, and reptiles, and a Pericú skeleton acquired as a cultural repatriation. Outside, a whale skeleton has survived years of weather and occasional vandalism. The museum runs on minimal resources — the director has reportedly kept it open largely through personal commitment rather than municipal support — which gives it a certain handmade quality that is a genuine contrast to the slick resort operations surrounding it. Entry is cheap and often free. Allow an hour, and do not expect air-conditioning.
