Check out this amazing drone video of a beautiful state park near the great city of Rio de Janeiro, compliments of contributor Digital Peace. It's called Serra da Tiririca State Park. It's located on the Niteroi (eastern) side of Guanabara Bay, shred between the municipalities of Niterói and Maricá. The park includes eight small mountains, the tallest of which is a bit over 400 meters (around 1.35k ft.), plus a marine park. The park was created in the 1980's in response to concerns about pollution.
