Serra da Tiririca State Park, State park in Niterói, Brazil

Serra da Tiririca State Park is a protected area in Niterói that combines mountainous terrain with coastal sections. The land is covered in Atlantic Forest with trails that pass through different landscapes and vegetation types.

The park's creation stemmed from a civil society campaign that began in the early 1980s against an illegal subdivision; a Public Civil Action, the first of its kind in Brazil, was filed. The Ecological Citizenship Movement prepared the technical and legal basis, forwarded through deputy Carlos Minc, and state law 1.902 created the park on 29 November 1991. UNESCO included it in the Atlantic Forest Biosphere Reserve on 10 October 1992.

The park contains remains of ancient shell mounds from indigenous settlements that show continuous habitation over thousands of years. These archaeological traces help visitors understand how people lived in this coastal area long ago.

The park is open during daytime hours and has a visitor center in the Itacoatiara neighborhood. Visitors should wear sturdy shoes and bring water, as the trails include hilly sections and can be exposed to sun.

A named trail follows the exact route that Darwin took during his visit in the 1800s. This path through the forest connects two locations and lets visitors walk where the famous explorer once traveled.
