The municipality is contained in the 59985 km2 Marajó Archipelago Environmental Protection Area, a sustainable use conservation unit established in 1989 to protect the environment of the delta region. The municipal seat lies at the mouth of the Cajari River where it enters the Baía do Vieira Grande. The municipality contains the 65181 ha Charapucu State Park, a strictly protected conservation unit created in 2010.

The town has been off-limits to cars since 2002, as there is no space for cars on the island where the town is located. It has been called the Venice of the Amazon, because many of the homes are on stilts and the town is only accessible by boat, though there is an airstrip in town which is often underwater. The town's mayor has described it as a model for net-zero emissions.
