Summer in San Martín de los Andes

San Martín de los Andes is the Lake District's most elegant mountain town, and summer is its finest season. Drive the Seven Lakes Route, swim in Lago Lácar, hike Lanín National Park, and enjoy boutique shopping and dining from December to February.

San Martín de los Andes is widely considered the most beautiful and sophisticated town in Argentina's Lake District. Perched at the eastern end of Lago Lácar in Neuquén province, surrounded by the forests and peaks of Lanín National Park, this town of about 30,000 exudes alpine elegance with its wood-and-stone architecture, pedestrian streets, and refined dining scene.

Summer from December through February transforms San Martín into a vibrant outdoor hub while maintaining the graceful atmosphere that distinguishes it from busier Bariloche. Temperatures climb to a pleasant 24-28°C, Lago Lácar warms enough for swimming at its sandy beaches, and the mountains and forests are fully accessible for hiking, biking, and horseback riding.

The town's position at one end of the famous Seven Lakes Route (Ruta de los Siete Lagos) makes it the perfect starting or ending point for one of South America's most scenic drives. The 110km route to Bariloche passes seven lakes of different colors and sizes, with countless photo stops and short hikes along the way. In summer, this drive is at its absolute best with clear skies, green forests, and shimmering blue lakes.

Beyond the scenic driving, summer opens up Lanín National Park with its volcano treks, araucaria forests, and pristine lakes. The Cerro Chapelco ski area becomes a mountain biking and hiking destination with chairlift access. And the town's growing gastronomy scene offers everything from Patagonian lamb and smoked trout to craft beer and artisanal chocolate. A rental car unlocks the full potential of this stunning area.

Frequently Asked Questions

How do I get to San Martín de los Andes?

Fly to Chapelco airport (20 minutes from town) with flights from Buenos Aires. Or drive from Bariloche via the Seven Lakes Route (3 hours, scenic) or from Neuquén city (about 5 hours). Rent a car at the airport or in town.

Which is better — San Martín or Bariloche?

San Martín is smaller, more elegant, and more relaxed. Bariloche is larger with more activities, nightlife, and options. San Martín is better for a refined, peaceful experience; Bariloche for variety and energy. Ideally, visit both by driving the Seven Lakes Route.

Can I swim in Lago Lácar?

Yes! Summer temperatures make the lake enjoyable for swimming, particularly at Quila Quina beach and the main town beaches. Water temperature reaches about 18-20°C in sheltered bays — refreshing but comfortable on hot days.

Is the Seven Lakes Route doable as a day trip?

Yes, as a round trip from San Martín or as a one-way drive to Bariloche (or vice versa). Allow a full day to properly enjoy the viewpoints and short walks. With a rental car, you set your own pace. The route is equally beautiful in both directions.

What dining should I not miss?

San Martín's food scene includes Patagonian lamb, locally smoked trout and deer, artisanal chocolates, craft beer, and regional cheeses. The Avenida San Martín and its side streets have excellent restaurants with outdoor summer terraces.
