It’s often best to hire a car, and wise to check in with park ranger stations and arrange stays at refugios (mountain shelters). Park rangers can supply maps, guides, and updated info.
Framed by soaring Andean peaks, the Northwest delivers numerous day hikes and multi-day expeditions through fantastically shaped canyons. The colonial city of Salta is the local visitor epicenter. Some 116mi (187km) north, the charming wine-growing region of Cafayate is the hub for Valles Calchaquíes, where traditional villages nestle amid the thrusting rock formations of the Quebrada de las Flechas. From Cafayate, a scenic, 3mi (5km) hike leads southwest to the Rio Colorado, home to ancient pictographs and a picturesque waterfall.
Just north of the city of Jujuy (75mi/120km north of Salta), the Quebrada de Humahuaca is Northwest Argentina’s main calling card. A UNESCO World Heritage Site, this long gorge blazes with waves of vividly colored rock, stretching north to the Bolivian border. Most tourist attention centers on the spectacular Cerro de Siete Colores, the stratified Hill of Seven Colors, which you can marvel at on a 90-minute hike (1.8mi/3km) around the perimeter.
Nestled beneath the mountain, Purmamarca is a captivating village despite its steady traffic of visitors, and with its rich indigenous traditions and incredible setting, it’s an ideal base for hikes and treks for all levels.
Adventurous trekkers and budding botanists head west to Calilegua National Park, 106mi (170km) northeast of Purmamarca. Home to portions of the Yungas cloud forest that covers swathes of Peru, Bolivia, and Argentina, its lush biodiversity is a far cry from Salta’s arid landscape.
Accessed from the town of Libertador General San Martín (6mi/9km away), the park has 14mi (22km) of trails for all abilities, which lead from the Aguas Negras ranger station and allow for close encounters with the park’s prolific wildlife inventory: 300 species of bird, including the majestic Andean condor, and 60 mammals, including puma and jaguar.
Novice trails include the short but rewarding Momota and La Herradura trails. If you want to make the heart valves squeak, more arduous hikes include trails to La Lagunita (five hours) and Tataupa (2.5 hours) that descend to the river. Multi-day expeditions can be arranged in Salta and San Salvador de Jujuy and include a three-day trek to Cerro Amarillo (12,205ft/3,720m) or Cerro Hermoso (10,499ft/3,200m).

The Normal and Polish Traverse routes to the summit don’t require gear or technical expertise, but they’re essential for the tougher Polish Glacier route, which involves crossing a glacier.

If you’re not up for a long commitment, rewarding day hikes are accessible from Mendoza City. Some 7.5mi (12km) west of town, El Challao is a popular, family-friendly hike. The hike to Cerro Arco (three-hour return trip to the summit) provides glorious panoramas of the city.
Less than a three-hour drive from Mendoza, Cerro Penitentes (14,272ft/4,350m), named for its jagged rock formations that resemble penitent monks, can be climbed all year round. While the moderately rated two-day hike (16mi/26km, with an overnight camp at the summit) requires no technical expertise, it does require a high level of fitness and hiking experience.
