Things to do in Brazil in May

There are many exciting things to do in Brazil, but we suggest you check out the most interesting ones to do in May.

Boat trips in the Amazon

May is a rewarding time to explore the Amazon by boat, as the rainy season tapers off and the rainforest is still lush and vibrant. River levels remain high, opening up flooded forests and hidden tributaries that are harder to reach later in the year, which gives 5-day Brazil trips a richer sense of the region’s waterways without requiring a long expedition. As you cruise along the Amazon River and its vast network of channels, look out for exotic birds, monkeys, and, with luck, pink river dolphins.

The cooler, drier weather makes it more comfortable to explore the city’s hilly streets and historical landmarks, such as the Church of São Francisco de Assis and the Museum of the Inconfidência. Join a guided walking tour to dive deep into Ouro Preto’s role in Brazil’s gold rush, marvel at its ornate churches, and discover its vibrant local culture.
