Discover the Ventana Mountains

The Sierra de la Ventana mountains stretch from Laguna del Monte in the northwest all the way to the Atlantic Ocean in the southwest. These mountains are super old! They formed about 2.2 billion years ago from ancient rocks. You can find different types of rocks here, like granite and amphibole.

What Makes These Mountains Special?

These mountains have steep slopes called escarpments. Because of these slopes, not much fine soil (called loess) built up here. This means the area isn't the best for growing lots of crops, unlike other parts of the Pampas. However, you'll often see fields of sunflowers growing at the base of the mountains.

The climate here is a bit cooler and drier than the areas around it. But it still gets more rain than the really dry parts of the Pampas to the west. You might also spot some unique trees called lacebark pines growing here, which might have come from Asia.

Exploring the Peaks and Caves

The Sierra de la Ventana range isn't super tall or wide, but it's full of interesting caves and grottoes. Only six of its peaks are taller than 1,000 meters (about 3,280 feet). The tallest one is Cerro Tres Picos!

Here are the highest peaks:

Cura Malal Chico (1,000 m)
Cura Malal Grande (1,037 m)
Napostá Grande (1,108 m)
La Ventana (1,184 m)
Destierro Primero (1,172 m)
Tres Picos (1,239 m)

History and Tourism in the Mountains

Did you know that the famous British naturalist Charles Darwin wrote about climbing the Sierra de la Ventana mountains? He described his adventure in his book, The Voyage of the Beagle.

In the early 1900s, people started to discover how lovely the region was. Its gentle breezes and mild weather made it a popular place to visit. A businessman named Ernesto Tornquist helped make it a tourist spot. When the Buenos Aires Great Southern Railway extended its tracks to the area, a fancy hotel and casino called the Club Hotel de la Ventana was built. A resort town called Villa Ventana also grew up nearby.

The hotel eventually closed, but the area remains a beautiful place for visitors to enjoy nature and the outdoors.
