Serra do Divisor
All of Brazil, within reach.
A diagonal divides the flag into yellow (upper left) and green (lower right), echoing the national colors, with a red star, the 'Estrela Altaneira', honoring those who fought for Acre's annexation to Brazil. The design derives from the 1899 flag of the Independent State of Acre and was formalized by state law in 1995.

About Serra do Divisor
Serra do Divisor National Park lies in the extreme west of Brazil, along the Peruvian border in Acre. Created on 16 June 1989 and managed by ICMBio, it covers about 837,500 hectares across five municipalities, with Mâncio Lima, Porto Walter and Cruzeiro do Sul holding the largest shares. Its name comes from the watershed it follows, which divides the Ucayali basin in Peru from the Juruá basin in Brazil. Four mountain massifs separated by river valleys give Acre its only true uplands, with altitudes from about 200 m to 609 m, the highest point in the state. Lying in the transition between the Amazon lowlands and the Andean foothills, the park is considered one of the most biodiverse areas in the Amazon: ICMBio counts more than 1,200 animal species, among them the red uakari, jaguar and giant anteater, and some 500 birds including the Acre antshrike, described to science in 2004. It has been on Brazil's tentative list for UNESCO World Heritage since 1998, and traditional families still live along its rivers. For agencies, Serra do Divisor suits small private groups and FIT who want remote Amazon nature without crowds: waterfall walks, river trips on the Moa, birding and primate watching, dark-sky nights and a multi-day trek to Cachoeira Formosa. It is not suited to large groups or MICE. Logistics require lead time. Clients fly to Cruzeiro do Sul, drive about 30 minutes to Mâncio Lima and continue by motorised canoe on the Japiim and Moa rivers, around seven to eight hours to the Serra do Moa area. Accommodation is limited to three family-run community lodges with full board, transfers, guides and excursions, so capacity is small and bookings must be made through them or an experienced local operator. The park recorded 2,995 visitors in 2024. Most waterfalls are short walks from the lodges, while the Mirante trail climbs to about 600 m. Pack warm layers, as nights on the heights can fall to around 7°C in June and July.
