The trip was fantastic. I absolutely recommend it. We had perfect cloudy weather, and the visibility was excellent. We saw a lot of dolphins, and I mean a lot, and they were very curious, swimming right next to the boat. We even encountered a school of fish with dolphins hunting around and birds taking advantage of the situation. After that, there was some speedy cruising, and we went by the Belem Tower and nearby monuments, getting historical information from the guide. The people organizing this trip were great, and I cannot recommend this experience more.
