Extraordinary biodiversity makes Paraguay a notable destination for ecotourism, in particular bird-watching. Hot spots for bird- and wildlife-watching include Parque Nacional San Rafael, Mbaracayú Biosphere Reserve and the Laguna Capitán area of the Chaco.
Despite the large open spaces, hiking and camping are difficult. Much of the land is privately owned, and even the national parks usually only have a limited trail system. You are strongly advised to not attempt to camp in the Chaco unless accompanied by a local guide. People go missing every year.
