We just got back from a great vacation at Frade during Carnaval. It is great for running because there are mountains that come straight up to the ocean. But one of the most enjoyable things is to rent a boat and go swimming. Off the coast of Frade are over 300 little islands. It is a snorkeling and diving paradise. Here is a video we took of a few of the dives. I literally can dive and swim with the fishes for hours on end.
