This gorgeous National Park is located about 75 km north of Rio de Janeiro (about an hour's drive from the International Airport), between Guapimirim and Teresópolis. Entrance fee was 30 reais (about US$15). There is a website for this park. No food concession, but campsites are available, and there is a small gift shop. I wish I had more time to explore this park - I visited for about an hour and a half late Saturday afternoon before heading back to the airport for my overnight flight back to Atlanta, connecting to Denver.
