Kaa Iya National Park
This area was relatively tourist-free, but I bumped into an Italian and a Dutch who were attempting a trip into the nearby Kaa-Iya National Park. Despite being Latin America’s largest park in terms of surface, Kaa-Iya is not open to tourists (although the planned construction of a tourist bungalow could change this); by sheer luck, we were granted authorisation to visit the parc, and even though we didn’t see as much wildlife as we had hoped, we did spend one great night by a natural well admiring the sound and light show created by fireflies and other insects.
