Nice looking 17 year old park with two pools, one of them kidney shaped and a double-pool with shallow and deep-end. Two concrete mini-ramps stand back to back with a spine connecting them.
The park is close to the Granollers bus station in Granollers, around 40 kilometers from Barcelona. Take the RENFE train from Estacio Sants to Granollers Centre. From the train station take the first right on the main boulvard (thanks to Andy Tucker for the updated info!). You should bring a broom to seep out the flat!
