We were really looking forward to this as part of our vacation and signed up for this experience for my husband's birthday. Communication wasn't a strength from this host, unfortunately, which had a negative impact on our experience. For the paddle boarding portion, you stay in one area and just repeat what you've practiced. The experience doesn't take you anywhere, just stay near the coastline.
We drove in from Bilbao for this experience but ultimately didn't find that the excursion was worthwhile. The beach was nice, worth a trip there in itself.
As a note, there's traffic coming into town. Ask the host for parking info in advance so you can download the app to pay for parking and/or bring coins to pay on site to avoid delays.
