Just 30 minutes from downtown on the idyllic Porto das Dunas Beach is this enormous water park. A 14-story-high waterslide dumps you into a pool at a speed of 105 kph (65 mph), or if you prefer slow-paced attractions, visit its museum, which has the country's largest collection of jangadas, the wooden sailing rafts used by fishermen. An open-air restaurant at the beach serves excellent seafood dishes. There is no bus from downtown, and a taxi costs around R$50.
