Carlos Botelho State Park, State park in São Paulo state, Brazil

Carlos Botelho State Park covers 37,644 hectares of the Serra da Macaca, from 50 to 975 metres in altitude, across the municipalities of Capão Bonito, São Miguel Arcanjo and Sete Barras. Its vegetation is mainly montane and submontane Atlantic rainforest, with a continuous canopy over 20 metres high in preserved stretches and bamboo-rich areas of Guadua tagoara.

Four separate forest reserves created in 1941 merged into a single protected park in 1982, establishing stronger conservation across a wider area. This consolidation made management more effective and allowed the forest to recover as one continuous ecosystem.

The park's name honours Carlos Botelho, a São Paulo state official of the 1940s. At the São Miguel Arcanjo headquarters, the Environmental Education Center holds a zoology museum and a library of ecology publications, and the Marco Antônio dos Santos Costa center screens environmental films in a 40-seat auditorium. The Figueira trail at Sete Barras ends at a huge old fig tree.

The Figueira trail at the Sete Barras center runs 2 km to a large old fig tree. Near the São Miguel Arcanjo headquarters, the Rio Taquaral trail is 4 km and signposted for students, while the Represa e Fornos trail covers 7.2 km, takes about three and a half hours and requires a guide. Some trails take more than a day.

Of roughly 1,200 southern muriquis left in Brazil, more than half live in this park, which also shelters the jaguar and the black-fronted piping guan. The 2011 plant inventory recorded 1,143 vascular species, over 60 of them endangered, and evidence of illegal palmito-juçara logging is still common in some areas.
