Macieira is a campsite within Parque Nacional do Caparaó, situated in Minas Gerais at an elevation above 1,800 meters. The park is home to Pico da Bandeira, the third-highest mountain in Brazil, making this a notable destination for trekkers and mountaineers.

The campground sits at the ecological transition zone between Atlantic Forest and high-altitude grasslands (campos de altitude).

The Ribeirão São Domingos flows nearby, and the moisture it carries contributes to the formation of frost at this elevation — a striking feature of mornings at the site.
