Caracol Museo de Ciencias is Ensenada's main hands-on science museum, set close enough to the waterfront to combine with the malecón and fish market. Exhibits are aimed largely at children and families, with themes around Baja California's environment, science, and technology.
It is a practical stop if you are travelling with kids or need a change from seafood, wine, and sea views. Adults without children may find it modest, but the location and local focus make it a useful piece of Ensenada's civic side.
