Open all year round, specific sectors may be limited by weather conditions.
Recommended field and sighting activities from November to March, when the weather is milder.
The reserve is immersed in the ecoregion of Patagonian forests, serving as a bridge between the Andean steppe and mountain forests. In the elevated and humid areas, scattered forests of lengas, yres, mountain cypresses and notros grow, which form a cool and shady environment.
In drier valleys, resistant shrubs predominate, such as caulk, molle, as well as dense coirón pastures, where vegetation adapts to wind, drought and poor soils.
During the southern spring and summer, between November and January, delicate wild flowers emerge - small daisies, wild fruits and less common species - that add subtle touches of color to the austere landscape
The Tucu-Tucu Provincial Reserve preserves a typical Patagonian fauna, adapted to a harsh climate environment. The huemul, an endangered Andean deer, the puma, and numerous herds of guanacos stand out. Smaller carnivores include the red fox and the Patagonian fox. The skies are flown over by the Andean condor, the moray eagle and the peregrine falcon, while the scattered shrubs and forests are home to birds such as the Patagonian carpenter and the garnet hummingbird. Especially important is the Tucu Tucu del Sur, a small endemic rodent that gives its name to the reserve and whose presence is a symbol of its ecological value.
