Batalla del Vino de Haro ★ 4.7
On 29 June, San Pedro's day, the people of Haro follow the mayor on a seven-kilometre procession up to the Hermitage of San Felices in the Bilibio cliffs, then drench one another in red wine from jugs, buckets and bottles. Declared of National Tourist Interest in 1965.
Tip: Wear white, bring a change of clothes and a wine-proof bag for your phone; the 7am climb to San Felices is the heart of it, not the town square.
