Sailing along the beaches is beautiful. You can also rent a boat with a guide and visit "Areia Vermelha Island", which only appears when the tide is low. (please, take a look at Must see activities, water ice-cream)
Equipment: There are many marinas on the beaches. The best places to rent boats with guides are Bessa Beach or Camboinha Beach.
It is a very funny sport...how can we call it?parachuting or skiing?
Kitesurfing is the name of this sport, I didn't know but one of the members here helped me. Thanks!!
