Carhué: Salt Lake, Flamingos and Cultural Heritage

Carhué brings together nature, thermal waters, architecture, and regional history. For planning your trip, these themes can be considered separately: Lago Epecuén is known for its saltwater and flamingos, while the Termas de Epecuén are known for their therapeutic thermal waters. The Palacio Municipal, the Ruta Salamónica, and the Ranchito at Casa de la Última Fortinera add architectural and historical connections. A nearby ecotourism trail and a trail-running event are also possible points of interest during your stay.

Nature at Lago Epecuén

Lago Epecuén is considered a natural floatation pool; its water is ten times saltier than the sea. The lake is also home to the second-largest breeding colony of South American flamingos in the Americas. Its salinity and birdlife offer two distinct perspectives on the same natural area: you can plan your trip around its unusual water or your interest in flamingos without treating the two as the same thing.

In winter, sulfate crystallizes along the shore of Lago Epecuén in low temperatures. This creates the natural phenomenon known as “salt snow.” Winter is therefore the relevant season if you want to include this seasonal feature in your plans.

Thermal Waters and an Ecotourism Trail

The Termas de Epecuén offer something different from the lake: their waters are therapeutic and hypermineralized, containing around 200 grams of salt per liter. The salinity is an approximate figure; individual spa services may vary. This makes the natural characteristics of Lago Epecuén and the thermal waters of the Termas two distinct themes to consider for your trip.

Five kilometers from Carhué, the Sendero del Molle is located at Camping Municipal La Chacra. The trail is intended for ecotourism. Its distance indicates its location relative to the destination, while its designated purpose distinguishes it from the bodies of water and their properties.

Architecture and History in Carhué

Carhué is one of the main locations on the Ruta Salamónica. One notable building along the route is the Palacio Municipal, one of the works of Francisco Salamone, a leading Art Deco architect. The named building and its architect are thus part of Carhué’s wider connection to the Ruta Salamónica.

The Ranchito belonging to the Casa de la Última Fortinera also offers a historical point of interest. It was declared a historic site in 1997. Together, these offer different cultural perspectives: the architecture of Francisco Salamone and the historic designation of a specific site.

Trail Running and Practical Information

Carhué hosted the ninth edition of the Vuelta al Lago Epecuén trail-running event. The 2026 edition’s course crossed rural roads, nature trails, ravines, and salt flats, as well as the ruins of the former Villa Epecuén. The route combines varied terrain with a historic ruin site, offering a specific point of interest for travelers interested in trail running and landscapes.

The Museo Casa de la Última Fortinera is listed as open daily from 1 to 5 p.m. Confirm opening hours before you arrive, as museum hours may change.

During one season, Playa Eco-Sustentable de Carhué had an amphibious chair to help people with reduced mobility use the beach. As this information is seasonal, check before your trip whether the chair and beach services will be available when you visit.
