Windsurfing (surf a vela), body boarding, wakeboarding, waterskiing and kitesurfing are all popular. There are water sports centres within the city where you can hire equipment or take lessons, but the better centres, offering a wider range of activities, can be found along the Costa Brava (particularly around Empuriabrava, Sant Pere Pescador and L’Escala). If you're serious about surfing, the Atlantic coast in northern Spain has much bigger waves. Barceloneta and Port Olímpic are the best spots in the city for renting out windsurfing equipment. It can cost as little as €60 per day for equipment and the help of an instructor. Aside from the clubs entered below, useful organisations to contact are the Real Club Naútico Barcelona (93 231 65 21, www.rcnb.com) and the Reial Club Marítim Barcelona (www.maritimbarcelona.org). Bear in mind that most sailing clubs offer other watersports. Official organisations include the Catalan Windsurf Association (www.windsurfcat.com) and the Catalan Kitesurfing Association (www.ack.cat).
