Along Pilcomayo River, between Laguna Blanca and Laguna Naineck towns (where you will find services, various cuisine options and accommodations), you can spot incredibly diverse fauna and flora species of this national park, as well as explore its estuaries, lagoons, palm groves, gallery forests and grasslands. It was designated as a RAMSAR site (a wetland of international importance) and it is considered a must-see for those who love eco-tourism. This easily accessible park offers 2 areas for public use: Estero Poí and Laguna Blanca. Estero Poí recreational area Drive 9 km on National Route 86 from Laguna Blanca town to discover the most peculiar landscape in Río Pilcomayo National Park: the savannah with caranday palm trees, and the termite mounds where giant anteaters search for their little prey. You can stay in the wild camp site, explore a short self-guided trail, or drive along a road across the park up to the bank of the river, where 4 different trails and several viewpoints and inns await you. Laguna Blanca recreational area Located 8 km from Laguna Naineck town, this recreational area offers different walkways with 2 low-difficulty interpretive trails.

Bañado La Estrella: El vertedero

Bañado La Estrella is one of the largest wetlands in South America and is considered one of the Natural Wonders of Argentina. In its 400 thousand hectares, this place features lagoons, marshlands, palm groves and "champales" (freshwater swamp forests covered by creepers). Explore El Bañado by sailing its waters, observing its flora and fauna, visiting native “criollo” communities, and going on photo safaris, and other excursions. This site is considered an Important Bird Area (IBA). On Provincial Route 28, about 40km from Las Lomitas, find El Vertedero hydroway construction work on the banks of El Bañado . Look down to the mirror-still water from the bridge, where you will spot dried trunks emerging from the surface, which are home to neotropic cormorants, capybaras, and caiman yacares. This easily accessible place invites you to enjoy the wetlands and wildlife: don't miss the reddish sunset, one of the most sought-after pictures.

Bañado La Estrella: Fortín La Soledad

Fortín La Soledad is a rural location at the heart of Bañado La Estrella. Almost 80 families live there and offer community tourism: they themselves will provide accommodation and offer excursions.

To arrive at this site, take Provincial Route 32 and drive 65 km from Las Lomitas. This gravel road goes across the Bañado, the best option to explore the local flora and fauna in its full beauty.
