Last updated:

Travel from Mercedes to one well-supported Iberá gateway and stay there: Colonia Carlos Pellegrini beside Portal Laguna. A confirmed local guide opens one lagoon journey in the Provincial Park, while current National Park trails, birding and village food give the wetlands time and context. The route never treats a wildlife sighting as guaranteed and never chains distant portals merely to inflate the stop count.

Iberá Wetlands: Mercedes & Carlos Pellegrini is a 240 km loop (mixed transport). It works best as 4–5 days; the plan below is the 5-day version for September, built from 14 verified places, with planned transit times, opening hours and daylight checked.

When to go

Best months: April, May, June, July, August, September, October

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.
