South and west of Salta, the land turns dry and red, and a chain of high valleys known as the Valles Calchaquies unfolds along the eastern foot of the Andes. This is wine country, cactus country and some of Argentina's most photogenic road, and it can be experienced as a single long day trip to Cafayate or as a two- or three-day loop. This guide explains the options so you can choose the one that fits your time.
The Quebrada de las Conchas
The road to Cafayate, National Route 68, passes through a long canyon of sculpted red sandstone, with short stops at named formations. The Devil's Throat is a narrow chasm, the Amphitheatre is a huge natural arena with remarkable acoustics, the Castles are jagged towers and the Obelisk is a lone spire. Most tours stop at several of these and drive on through the afternoon. Morning light is excellent for the outbound journey, and golden light on the return makes the walls glow.
Cafayate and its wines
The town of Cafayate sits at about 1,700 metres, and its vineyards climb to far higher altitudes. Sun, dry air and cool nights produce fragrant Torrontes, a white that smells of roses and peaches, as well as Malbec, Cabernet Sauvignon and the dark Tannat. A good winery visit includes a walk among the vines, an explanation of altitude viticulture, a look at the cellar and a tasting, and many offer lunch. The town itself has a pleasant plaza, a wine museum, artisan shops and ice cream flavoured with wine. A day trip allows one or two wineries, while an overnight allows more and a sunset on the terrace.
Cachi and Los Cardones
The northern part of the valleys is reached over the Cuesta del Obispo, a winding road that rises to about 3,300 metres before descending onto a high plain dotted with giant cardon cacti in Los Cardones National Park. Beyond lies the straight stretch known as the Recta del Tin Tin and the whitewashed village of Cachi, with a church made of cardon wood, a small archaeological museum and views of snowy peaks. It makes a superb full-day trip from Salta.
The Route 40 loop
Combine the two directions and you have the classic journey: Salta to Cachi over the Cuesta del Obispo, south through Molinos, Angastaco and the Quebrada de las Flechas to Cafayate, then back to Salta through the Quebrada de las Conchas. Molinos has a colonial church and an old hacienda, Angastaco has small wineries among red hills and the Quebrada de las Flechas has arrow-like rock fins. A guided two-day trip handles the logistics, and the overnight lets you see the valleys at dusk and dawn. Add a third night if you want to slow down and visit more bodegas.
Driving and logistics
Distances are long, and some stretches are gravel. If you hire a car, fill up whenever you can, carry water and cash, and start early in the day. Weather can close roads in the summer rainy season, and the Cuesta del Obispo may be affected, so check conditions. Drivers should not taste wine and drive; use a driver or a guided tour for wine days. Mobile coverage is patchy, so download offline maps.
Seasons
Autumn brings the grape harvest and golden vines, which is a lovely time for wineries. Winter is cold at night but sunny and clear. Spring is green and fresh, with cactus flowers. Summer is hot and can bring storms in the afternoon, but the valleys are green. In every season, wear a hat, carry water and keep a layer for the cool evening.
Beyond the vineyards
Cafayate offers more than tasting rooms. Cyclists can ride between bodegas on quiet roads, riders can arrange horse outings among the vines, and dune and desert walks are possible near the town. Local artisans sell textiles, ceramics and wine-related gifts, and small museums explain the history of the grape in the region. If you have time, a quiet afternoon on the plaza with a coffee and a regional pastry is part of the experience, and an evening stroll under the clear sky reveals how dark and starry the valley nights can be.
Where to stay
In Cafayate, choose between a wine hotel on the edge of town, a vineyard resort or a simple hotel on the plaza, depending on budget and mood. In Cachi, a small hotel or guesthouse gives access to quiet evenings. Book ahead for holiday weekends, when the valleys fill with visitors from across Argentina.
