Queen Mary explored the Amazon Rainforest as she kicked off her four-day solo visit to Brazil on Wednesday.
The Danish queen, 52, looked effortlessly chic in a sage green utility shirt and brown cargo trousers as she took a boat trip on the Amazon River and visited part of the rainforest nature reserve.
In the evening, Mary met with the governor of the state of Amazonas, Wilson Lima, at Teatro Amazonas, a theatre and opera house in the centre of Manaus.

Mary is on an official trip to the South American country from 2 to 5 October with Climate, Energy and Supply Minister Lars Aagaard to focus on Danish-Brazilian cooperation on biodiversity, health and the fight against violence against women.

The visit began with a boat trip, where Mary learned about the Amazon's river systems. We love this picture of the queen looking out across the river from the boat.
At the Adolpho Ducke forest reserve, Mary got an insight into the challenges of the Amazon region and solutions in relation to combating environmental related crime. Denmark has previously pledged support for the Amazon Foundation, which fights illegal deforestation of the rainforest and promotes sustainable development.
The Amazon Rainforest is called by some the "lungs of the world" and Mary got to witness its beauty up close from a 42-metre observation tower at the Museum of the Amazon (MUSA).
