Best Time for Iberá Wetlands: Mercedes & Carlos Pellegrini

Last updated: 2026-09-15

Preferred months for this journey: April, May, June, July, August, September, October. Check the seasonal notes before choosing your dates.

Cooler months suit longer walks and midday wildlife watching. The park remains open year-round, but every sighting, trail, guided lagoon departure and unsealed-road approach still depends on current conditions.
In the hotter months, begin outdoor visits early, rest around midday and resume later. Confirm storms, recent rain, road condition, shade, water, the open trail and the guided excursion before setting out.
