Hola,
I am struggling to find any boat tours of the Basque Geopark/Flysch in English. Does anyone know of any? Gracias!
My friends of Begibistan do boat tours of the area, https://www.begi-bistan.com/en/flysch/, I´m assuming you´re referring to the flysch in Zumaia.
If you can’t find a boat tour you can get a good view of the flysch formations from Zumaia’s beach and from Observatorio balcón al Cantábrico and San Telmo chapel.
Thank you Mikel, I will check out your friend's website. Thank you, Jamie, for the observation sites of the flysch out of Zumaia!
