Like every Holy Week we have met with the Gorbeialdea crew for another year of caving. The objective of this outing is to learn about the history and mythology of the place by immersing yourself in the Mairulegorreta caves.
Did you know that the only river moonmilk is in Altzola? It is a white underground river, of liquid moon milk, which constitutes the first world report of this nature.
The largest cave in the world
