Take right when you reach the Pântano do Sul beach, you’ll see the place at your left. Usually uncrowded, it has its days, but usually the waves are all close outs. If you’re going on that direction, check it out.
Alternative surfing spot, produces good waves with S swell and N,W wind. Small beach with a good right. Follow the road from Praia dos Açores and make local inquiry to get exactly direction.
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.
