Welcome to Visconde de Mauá
The valley consists of three small villages a few kilometers apart along the Rio Preto, which forms the boundary between Rio de Janeiro and Minas Gerais states. The road passes first through Mauá, the largest village, then heads uphill to Maringá, 6km to the west, and Maromba, 2km further on, before petering out at the edge of the national park. Beyond Alto Maringá (upper Maringá village) the road remains unpaved; expect a bumpy ride!
Note that addresses in Maringá are marked ‘RJ’ or ‘MG’ to show whether they're on the Rio de Janeiro or the Minas Gerais side of the river.
