The Juatinga, sometimes called Joatinga Ecological Reserve is part of the Cairuu Environmental Protection Area and is situated on the southern end of Rio de Janeiro state, in the municipal of Paraty. (see Juatinga localization-, satellite- and topographic map).

The Reserve was created in 1992 in order to protect the Atlantic Rainforest and associated ecosystems Mangroves, Restinga and coastal rocks. Juatinga Ecological Reserve also shelters 12 tiny caiara communities, that are distributed along the coast line and sustent their lives with fishing, agriculture and traditional handycraft. The area is extremely rich in biodiversity and contains around 10.000 plant species.

Juatinga can best be explored by a 3 to 4 days hiking tour along a small trail used by the local communities (travessia da Joatinga). One of of the highlights of this trail is the Ponta da Juatinga with its impressive lighthouse.
