The city of Bariloche has a special quality. It is surrounded by 705,000 hectares of protected land. Parque Nacional Nahuel Huapi was created in 1934. The park encompasses the ominous mountains Tronador, Crespo and Cuyin Manzano, smaller mountains like Cerro Otto, Ventana and Lopez, as well as all peaks that border Chile. Other than the security that the dense, green forests will always be thriving, the park is a great thing because it was an excuse for a giant network of trails to be carved out of the Andes wooded land. And in the process Bariloche became a central location for over a dozen trail heads. These trails vary in length, difficulty and objective. While a portion of the paths are leisure day hikes, such as the circuit in Parque Muncipal Llao Llao, others are multi-day trekking adventures. The majority of the overnight trips venture towards refugios that were established in the 1950s by Club Andino, a national mountaineer organization. The huts are usually kept by a camp manager offering beds, hot meals, cold drinks and a warm fire. Some are even known to serve homemade beer. These hikes can be connected to create multiple weeks or more of backpacking. Many of the day hikes have fogones (fire pits) and picnic tables near the trail heads.
