The best thing I did in Praia de Pipa is to walk to a bay called Baia dos Golfinhos, close to this beach featured on the picture called Praia de Amor.
Baia dos Golfinhos is only accessible at low tide. If you are lucky, you can swim with dolphins.
Below is the video. I don’t know why the dolphins would not jump just in front of me, but there are 2 passing by, just in front of the paddle board!
No need to take a tourist boat as most people do, just swim 200m from the beach, and be patient. I swam for an hour and a half. Good exercice of flotation for my divemaster! Actually it was the first time I saw some while being in the water! Just fantastic!
