HI,

check out the event of the year:

Surf at Night '09 Raggae festival at Cortegaça Beach - 14 August

This is something you do not want to miss. Some of Portugal's best surfers will show their moves during a 2hr Expression Session. Afterwards it is time for free surfing...
Just imagine, surfing the whole night while listening live Raggae bands on the beach!
After the session, have a Caipirinha and enjoy the party...
