Rio  is a surfers’ haven, luring wave junkies from around the world to the beaches of Arpoador , Barra, Recreio, Prainha, and Grumari . If you want to hone your technique, Escola de Surf Rico de Souza (tel. 21/2438-1821, www.ricosurf.globo.com ) offers daily lessons at its headquarters (in front of Posto 4 at Barra) and at Prainha. Private lessons (including equipment) cost R$60 per person for one hour.
The school has lots of information about surfing conditions, events, and equipment rental. It even operates a special surfer bus service (R$2), with buses departing daily from Largo de Machado in Botafogo  and stopping off at all the best surf spots between Copacabana  and Prainha .
