on this page, the instituto estadual do ambiente - inea, provides the bathing suitability of several beaches, including praia de grumari that can be used to determine water quality at praia do meio, which is normally very clean. constantly updated, the red flags mean that swimming is not advisable, green flags mean waters are clean, and yellow flags suggest using own judgment. any of rio's beaches may have polluted waters within 24 to 48 hours following heavy rains.

the actual 'adventure' beaches cannot be reached via taxi or bus - as taxis or buses can only get to the beach da barra de guaratiba, after which the wild shores can only be reached via hiking (about 60 minutes to praia dos búzios, the first beach) or via small boats, about 20 minutes to praia dos búzios.
