Maragogi is on the AL-101 highway, about 125km north of Maceió.
Go and visit the natural pools. However, in the high season, for example in January, you may need to book in advance to be able to get a space on a boat. There is a limit on the number of people that can visit these pools per day. The Maragogi pools are a popular day trip from Maceió, so being in Maragogi may not help to get a last-minute ticket. Tour organisers may offer to take you to the Japaratinga pools instead, which are nearby. These are not very special, do not go, unless you really can't wait a day or two for a tour in Maragogi.
