Salinas Grandes
Salinas Grandes
Perched above 3,400 m on the Puna, Salinas Grandes form a 212 km² salt desert with immaculate polygons. Artisanal extraction, spectacular reflections during the rainy season, and sweeping Andean vistas await.
Salinas Grandes sprawl across more than 3,400 metres altitude on the Puna, straddling Jujuy and Salta provinces. This salt desert of nearly 212 km² unfolds as an immaculate white mirror ringed by volcanoes and intense blue sky. It ranks among Argentina's largest salt flats, inhabited for centuries by indigenous communities who continue to extract salt by hand.
Quick facts at a glance

- Recommended duration: 1 to 2 hours on-site, usually part of a full day's drive.
- What to wear: sunglasses essential (intense glare), high-SPF sunscreen, warm clothing (cold wind even in summer).
- Accessibility: flat surface but unimproved; wheelchair navigation is difficult.
What you'll see
The salt flat presents itself as a cracked salt crust fractured into regular polygons—a hallmark of high-altitude salt flats. Extraction basins carved by local artisans reveal bluish brine. During the rainy season (December–March), a thin film of water transforms the surface into a perfect mirror, reflecting clouds and surrounding mountains.
History and context
Indigenous Puna communities have worked this salt since pre-Columbian times. Salinas Grandes salt was a major trading commodity along Andean routes, exchanged for products from the valleys and lowlands. Today, local cooperatives continue artisanal extraction and welcome visitors to the site.
Highlights of your visit
The salt polygons
The salt crust naturally fractures into hexagons and pentagons spanning several decimetres. Walking across this natural geometry, feeling it crackle underfoot, is a unique sensory experience in the Argentine landscape.
Artisanal extraction
Local artisans work shallow basins with pickaxe and shovel. Some cooperatives offer explanations of the process and sell carved salt blocks—typical keepsakes from the location.
The mirror effect in rainy season
Between December and March, a few centimetres of water coat the salt flat. The sky, clouds, and volcanoes reflect to infinity, creating breathtaking optical illusions highly prized by photographers.
Photography tips
Light is optimal in mid-morning and late afternoon—the midday sun flattens the texture of the crust. Wear colourful clothing: the contrast against white salt is stunning. During rainy season, shoot close to the ground to maximise the mirror effect. Protect your camera from salt dust and glare.
Location and access
Salinas Grandes lie on National Route 52, roughly 65 km west of Purmamarca. The road crosses Lipán Pass (4,170 m) before descending to the salt flat. Most visitors arrive from Purmamarca or San Salvador de Jujuy on a day trip. Local agencies offer transfers and guided tours from Jujuy or Salta. No regular public transport serves the salt flat directly.
Nearby attractions
- Purmamarca — colonial village nestled at the foot of Cerro de los Siete Colores, the natural springboard for visiting the salt flat.
- Quebrada de Humahuaca — UNESCO World Heritage valley, east of Purmamarca.
- Tilcara — village with a pucará (pre-Columbian fortress) and a lively craft market.
- San Antonio de los Cobres — mining town on the Puna, departure point for the Tren a las Nubes.
Frequently asked questions
The dry season (April–November) guarantees a clean, walkable salt surface. The rainy season (December–March) delivers the spectacular mirror effect, but the surface may be partially flooded and slippery underfoot.
Yes. The salt flat sits above 3,400 m. It's advisable to spend at least one night at Purmamarca (2,200 m) or Jujuy before ascending. Stay well hydrated and avoid strenuous exertion immediately upon arrival.
The central zone is accessible on foot. Respect artisanal extraction areas and do not walk through brine basins. Follow guidance from local cooperatives present on-site.
National Route 52 links Purmamarca to Salinas Grandes via Lipán Pass. A classic circuit departs Jujuy, traverses Quebrada de Humahuaca, stops in Purmamarca, climbs to the salt flat, then descends toward Salta via San Antonio de los Cobres.
Yes, photography is free on the site. If you wish to photograph artisans at work, ask permission first—a courtesy gesture appreciated by local communities.
A personal vehicle or organised tour is practically essential. National Route 52 is paved and navigable in a standard car, but no regular bus service reaches the salt flat directly.
