Ondarbeltz, Basque for 'black sand', is a 120 m beach of fine dark sand on the left bank of the Deba river mouth. It belongs to Mutriku but sits closer to Deba. The official beach guide describes its water as calm, with a rocky shelf exposed at low tide. We found no surf guide that describes a regular wave here.
