Salinas Grandes

Salinas Grandes is a 212 km² salt flat at 3,450 metres altitude on the border of Salta and Jujuy provinces in northwest Argentina, the most accessible high-Andean salt flat in the country and one of the iconic landscapes of the entire NOA region. Located in the high desert (Puna) west of the Quebrada de Humahuaca, the salt flat is reached by driving 66 km from Purmamarca on RN 52, crossing the dramatic Cuesta de Lipán mountain pass at 4,170 m. The salt is a 30 cm thick crust over brine that has been mined by the Atacama people for centuries — today the indigenous communities of Tres Morros, San Antonio de los Cobres and surrounding villages run cooperative tourism on the salt flat, charging a small fee for guided walks and selling salt-block crafts. The blinding white surface against the deep-blue Puna sky is one of the most photographed landscapes in Argentina, and the drive itself — through llama-grazed altiplano with views of the Andes — is half the experience. Most travellers visit as a day trip from Purmamarca or Salta city, but it can also be part of a multi-day route to San Pedro de Atacama (Chile) via the Paso de Jama border crossing, or to the Tren a las Nubes railway via San Antonio de los Cobres.

The Drive: Cuesta de Lipán

The drive from Purmamarca to Salinas Grandes is one of the most spectacular paved roads in Argentina. Leaving Purmamarca on RN 52, you climb steeply through hairpin switchbacks for 25 km, gaining nearly 2,000 metres of elevation in 1 hour. The pass, the Cuesta de Lipán, peaks at 4,170 m altitude — high enough that altitude sickness is a real risk if you went up too fast. There\'s a viewpoint at the top with a small parking area; stop, breathe, take photos of the panoramic view back down toward Purmamarca and the colourful sierras of the Quebrada. From the pass, the road descends gradually onto the Puna altiplano — a flat, treeless high-desert landscape with grazing llamas, vicuñas (wild relatives of the llama) and cardón cacti. After 40 km on the altiplano, the salt flat appears suddenly: a vast white plain stretching to the horizon, with the Andes rising in the distance.

On the Salt Flat

The access road runs onto the salt flat itself for ~2 km until you reach the visitor area — a simple cluster of stalls and a small visitor centre run by the indigenous community. Pay the small access fee (USD 2–5), then either take a guided walk or drive (slowly) onto the salt. Highlights:

The salt patterns

The surface is a hexagonal pattern of crystallised salt formations — the geometric tessellation comes from how the salt crystals grow as the brine evaporates. Up close, the hexagons are about 30–50 cm across; from above (drone shots), they form a spectacular grid that stretches to the horizon. Best photographed in morning light when the low sun casts long shadows across the patterns.

The "ojos de sal" (salt eyes)

Small pools of liquid brine that have broken through the salt crust, sometimes a metre across. The water is intensely turquoise from concentrated minerals, surrounded by white salt. They\'re scattered across the flat — your local guide will know where they are. Don\'t walk on them; the salt around the edges is fragile.

The salt mining operations

Local cooperatives still extract salt for sale — you\'ll see piles of fresh-cut salt blocks and the wooden tools used to harvest them. Some areas allow visitors to watch the mining; tipping the workers a few dollars is appreciated.

Photography tricks

The flat white surface is the world\'s easiest place for forced-perspective photos — small objects placed near the camera appear "giant" against people in the background, like the famous Bolivian Uyuni shots. Bring a small toy, a wine bottle, anything with a recognisable shape. Best light: 09:00–11:00 (warm shadows, blue sky) and 16:30–17:30 (golden hour with mountains lit).

Combining with Other Stops

1-day tour from Purmamarca

Most efficient: leave Purmamarca at 09:00, arrive Salinas Grandes 10:00, 2.5 hours on the salt flat, lunch in Purmamarca on the way back, total return by 14:00. USD 35–95 in a shared shuttle.

1-day tour from Salta city

The classic NOA day trip: Salta → Purmamarca (Cerro 7 Colores stop) → Cuesta de Lipán → Salinas Grandes → Tilcara → Salta. 12 hours, 460 km, exhausting but covers a lot of ground. USD 60–150. Better split into 2 days with overnight in Purmamarca or Tilcara.

Multi-day route: NOA + San Pedro de Atacama

Salinas Grandes is on the way from northern Argentina to San Pedro de Atacama (Chile) via the Paso de Jama border crossing at 4,200 m. The route: Salta → Purmamarca → Salinas Grandes → Susques (overnight) → Paso de Jama → San Pedro de Atacama. About 530 km from the salt flat, 8 hours of driving. The crossing requires a full passport check and entry to Chile takes 30–60 minutes. Many travellers continue to Bolivia\'s Salar de Uyuni from there.

Tren a las Nubes

The famous Train to the Clouds railway departs from San Antonio de los Cobres, 60 km south of Salinas Grandes (90 minutes by car). Trains run select days April–November. If you\'re in the area, this is the perfect combination — drive to Salinas Grandes, then south to San Antonio for the train.

What to Bring

• Sunglasses (very dark) — the glare off the white salt is intense, comparable to fresh snow.
• Sun cream + hat — UV at 3,450 m is much stronger than at sea level.
• Layers — temperatures swing 20°C+ between day and night, especially in winter.
• Water — at altitude you need 50% more water than usual.
• Snacks — there\'s a small shop on the salt flat but it\'s expensive and limited.
• Coca leaves — buy them in Purmamarca or Tilcara before going up. Help with altitude.
• Cash (small bills) — community access fee, tips, salt-block crafts. No card machines.
• Camera with wide-angle lens — phone is fine but a real camera captures the scale better.

Safety + Practical Notes

• Altitude: the biggest risk. If you have heart issues, hypertension or are over 70, consult a doctor first. Acclimatise in Purmamarca (2,200 m) for at least one night before going up.
• Fuel: there is no fuel station between Purmamarca and the salt flat. Fill up in Purmamarca (or in Susques if coming from Chile). The next station heading west toward Chile is in Susques (40 km from the salt flat).
• Mobile signal: none on the salt flat. Tell someone your itinerary before going.
• Weather: snow is possible at the Cuesta de Lipán pass any month of the year. Check road conditions (Vialidad Nacional) before driving in winter.
• Don\'t drive onto unmarked salt: the surface is fragile in places. Only drive where the road and the local guides indicate.
