Hiking trail in Between Cafayate and Salta, Salta Province, Argentina
Quebrada de las Conchas
Dramatic canyon walk through colorful sedimentary rock formations sculpted by millions of years of erosion. Natural formations nicknamed Garganta del Diablo, El Sapo, and El Anfiteatro create an otherworldly landscape in red, purple, and ochre tones.
The Quebrada de las Conchas — also known as the Quebrada de Cafayate — is a dramatic canyon system stretching approximately 47 km along National Route 68 between Cafayate and the city of Salta in Salta Province, northwest Argentina. The canyon cuts through layers of Triassic and Cretaceous sedimentary rock in extraordinary hues of red, purple, ochre, and pale yellow, eroded over millions of years by the Río de las Conchas (also called the Río Calchaquí). Hiking in the quebrada is largely self-guided, with visitors stopping at a series of named geological formations distributed along the road.
No permit or entry fee is required to hike in the quebrada. Access is straightforward: buses and remises (shared taxis) operate along Route 68 between Cafayate (approximately 65 km south) and Salta (approximately 120 km north), and will stop near the main formations on request. Guided day tours from both Cafayate and Salta are widely available and offer the most flexible multi-stop itinerary. Gravel parking pullouts are located beside all major formations for those travelling by private vehicle.
Walking distances vary by section. The most popular formations — Garganta del Diablo, El Sapo, El Fraile, and El Anfiteatro — lie within a compact stretch of the canyon and can be explored in 2 to 5 hours of combined walking, with each site requiring between 500 metres and 2 km on foot from the road. Trails are predominantly sandy canyon floor or bare rock surfaces, with minimal shade and largely flat to gently undulating terrain. A few formations involve short scrambles to access elevated viewpoints.
El Anfiteatro is a natural circular auditorium carved into the canyon wall whose near-perfect acoustic properties make it a popular impromptu performance space; local musicians occasionally play here for visiting groups. The Garganta del Diablo (Devil's Throat) is a narrow slot canyon with near-vertical walls reaching 50 metres in height, passable by foot to an interior viewpoint. The Los Colorados section near the quebrada's southern end features columns of brilliantly coloured red rock that resemble organ pipes.
Water sources are absent within the canyon itself. Visitors must carry all water needed for the day. Temperatures in the quebrada are significantly higher than in Cafayate or Salta, particularly in summer (December–February) when the canyon walls radiate absorbed heat intensely. Sun protection, electrolytes, and a wide-brimmed hat are essential items.

Tips
- The quebrada is best explored in the morning when low-angle sunlight illuminates the coloured canyon walls from the east; afternoon light flattens the colours significantly.
- Carry at least 2 litres of water per person — there are no sources within the canyon and the sandy terrain reflects heat intensely.
- Hiring a remis or joining a guided day tour from Cafayate is more practical than relying on public buses for flexible stops at multiple formations.
- Visit during the dry season (April–October) to avoid flash flood risk; the Río de las Conchas can rise rapidly after storms even when skies appear clear locally.
- Lightweight sun-protective clothing, a wide-brimmed hat, and high-SPF sunscreen are essential given the near-total lack of shade in most canyon sections.
FAQ
Is an entry fee required for the Quebrada de las Conchas?
No entry fee is charged. The canyon runs along a public national highway and all formation access points are open to visitors. The only cost is transport from Cafayate or Salta.
Is the quebrada accessible without a private vehicle?
Yes. Regular buses run between Cafayate and Salta along Route 68 and will stop near major formations on request. Guided day tours and remises from Cafayate offer the most flexible multi-stop itineraries and are the most popular option.
Can the quebrada be combined with a wine tour in Cafayate?
Yes, this is a very common combination. Cafayate is Argentina's second wine region, known for Malbec and Torrontés. Many tour operators combine a morning quebrada walk with bodega visits and tastings in the afternoon.
Are there safety risks in the canyon?
Flash flooding is the principal risk during the wet season (November–March); the dry season (April–October) is significantly safer. Heat stroke is a year-round concern — the canyon walls amplify solar radiation and visitors should pace themselves and hydrate consistently.
Accessibility
The canyon floor sections at most formations are traversed on firm sandy or rocky surfaces, and some portions close to the road can be navigated with a sturdy wheelchair or stroller on dry days. However, no formal accessible infrastructure exists; surfaces vary unpredictably and the Garganta del Diablo slot canyon involves loose sand and scrambling that is not wheelchair-compatible.
When to visit
April through October (the dry season) is strongly preferred; the landscape is most vivid and flash flood risk is minimal. Morning hours (8–11 am) offer the best lighting on the canyon walls. December through February brings intense heat and afternoon storm risk.
