The kids are sure to sleep soundly after playing by the seaside at Laidatxu Beach. Search for crabs and other little critters, dip a toe in the water or maybe even fly a kite!
You'll find this stretch of coastline in Mundaka. Once you've done everything you can at Laidatxu Beach, head to nearby San Juan de Gaztelugatxe, Urdaibai Biosphere Reserve, and Bosque Encantado de Oma.
