Incredible experience! We are from Rio de Janeiro, come to Paraty for our honeymoon. We saw some reviews of Saco so Mamangua and knew we just had to go. First, you must go to Paraty Mirim by car, it’s a bumpy drive and best if on 4x4 wheels. The road signs and pretty clear and there is really nowhere else to go but the main road. Once at the very end, there are a few places to park your car at about R$20 until 18h. There plenty of captains and boats to chose from, but we most definitely recommend Mateus! He is a young captain, born in one of the islands just off the coast, very experienced and knows every corner of the place. Respectful of our time and would let us very comfortable to enjoy each spot on our own time. All the captains charge the same price because they work together as a very tight community. We paid 800 just the two of us, visited every spot of the Mamangua area, stopped for swimming and jumping rocks, had lunch at Restaurante do Dadico - very fresh fish. Also did an hour hike to Pico Pão de Açúcar, Mateus leaves right at the beach where the trail begins and then will be waiting once your back. Totally worth it!
