Starting your trip from Bilbao you'll head to San Juan de Gaztelugatxe, which name means "rock castle" in Basque (gaztelu = castle + aitz = rock). You'll have 2 hours to walk across the stone bridge with 241 steps where it will seem like you're ascending to one of the most important fortresses in the series Game of Thrones: Dragonstone. You'll then visit the town of Bermeo, a fishing village with a deep-rooted seafaring tradition. Before finishing your excursion, you'll head towards Gernika, the Basque town that gives its name to the famous painting by Pablo Picasso, where you'll have the chance to visit the gardens of the “Gernika Assembly Hall”.
