30-40 min walk. It is worth the walk. Beautiful place, hollow waves at the right side , holds size and produces excellent barrels.
Prainha (Little beach) is a desert beach just beside Guarda do Embaú, it’s easily accessed by a 30 minutes hike over the left head of the beach.
Gamboa is not a popular wave, but when a solid south swell turns to east, don’t spend more time, head to Gamboa and you’ll get a long and perfect right hander. This place is calm and usually there’s no big crowd.
