Belém - the great entry to the Amazon. Best ice cream on earth, beautiful plazas, mango trees and the colonial Cidade Velha. Don't miss the Museu Emilio Goeldi, a beautiful forest park in the city center.
The great market Ver-o-Peso (Watch the weight). You'll find everything you need, from hammocks, pots and pans to clothes, plants and knives to fish, shrimp, açaí to fruit, vegetables and medicinal plants.
