Best Season

During these months, trails are generally snow-free, temperatures are mild and pleasant, and daylight hours are long. December to February are peak summer months, ideal for combining hikes with dips in the lakes, though trails can be busier. The shoulder seasons (November, March, April) offer fewer crowds and beautiful autumn colors in the forests.

  • !Wildlife encounters are possible, including puma. While rare, know how to react (make yourself look big, make noise, do not run). Maintain a safe distance from all wildlife.
  • !Some trails have steep sections or can be slippery, especially after rain. Use caution and consider trekking poles for stability.
  • !Always carry a map (physical and/or offline GPS), compass, and fully charged phone. Cell phone signal is often absent on trails within the park.

Getting There

San Martín de los Andes is the primary hub for accessing these hiking trails. The town is located on National Route 40, easily reachable by car from cities like Bariloche or Junín de los Andes. Many of the most rewarding trailheads, particularly those deeper within Lanín National Park or around Huechulafquen Lake, require a car. A rental car provides the essential flexibility to reach diverse starting points such as the base of Volcán Lanín, the remote Hua Hum Pass (via Ruta Provincial 62), Quila Quina, Yuco, and various points along the scenic 'Route of the Seven Lakes' (Ruta 40). Public transport options to some trailheads are limited, making a car rental highly recommended for independent hikers wanting to explore beyond immediate town limits.

Tips

  • 1Always register your hike at the nearest park ranger station or national park office, especially for longer or more remote trails, and notify them upon your return.
  • 2Carry sufficient water, as natural water sources can be unreliable or require purification.
  • 3Pack layers of clothing; Patagonian weather can change rapidly from sunny to windy and rainy.
  • 4Respect the 'Leave No Trace' principles: pack out everything you pack in, stay on marked trails, and minimize your impact on the environment.
  • 5Wear appropriate footwear. Even 'easy' trails can have uneven terrain.
  • 6Inform someone of your hiking plans and expected return time before heading out.
  • 7If hiking in areas close to Mapuche communities (e.g., Quila Quina), be respectful of their culture and land, and consider supporting local vendors.
