Let us propose you some plan: Discover the Basque coastline’s most stunning cave paintings, declared a UNESCO World Heritage Site and painted by the people who inhabited this place 15,000 years ago, through this magnificent replica. Between these paintings, there are “the best herds of horse paintings of the Quaternarian Art”. Get to Zestoa town (only 25 km from Orio Camping) and walk to the caves (remember to buy tickets first). More information, here.
