Paraguay receives fewer visitors than any of its neighbours, and what draws them is specific: the Jesuit mission ruins at Trinidad and Jesus in the south, Asuncion's riverside center, and the Chaco, a sparsely populated dry plain covering the country's western half.
The guides on this page cover Paraguay as a whole. Summer heat from December to February is severe on the plains, and the more comfortable months run May to September. The Chaco has minimal infrastructure and roads that deteriorate after rain, so travel there needs planning rather than improvisation. Spanish and Guarani are both official and both widely spoken in daily life.
