Castelldefels features some of Barcelona's best beaches, but if you're interested in more than a lazy day in the sun, it has something more to offer you. Kitesurfing has taken the extreme sports community by storm and Castelldefels is host to several kitesurfing events throughout the year, including events on the European Pro Kitesurfing tour.

If you'd like to get into the action yourself, the Mojo Kite School offers classes and equipment rentals.
