Fish Surf School is our partner for surf in Porto.

They are a certificated Surf School being the one who has more experience with Erasmus Students and in fact the one that the International Students do prefer.
They offer a free group surf lesson to all the ELP Card Holders and they will keep you updated of everything that happens around the surf environment in Portugal. 
From hundreds of international students, we got a surf feedback as we wouldn't get with any other partner: 100% satisfaction.
