Quebrada de Humahuaca

The Quebrada de Humahuaca is a 155 km long mountain canyon in the Argentine province of Jujuy, declared a UNESCO World Heritage Site in 2003 (#1116) for both its dramatic geology — millions of years of sedimentary layers exposed in multicoloured cliff faces — and its cultural significance as a 10,000-year-old route connecting the Andean highlands with the lowland plains. The canyon runs along National Route 9 north from Salta city, climbing from 1,200 m at the start to over 3,000 m at Humahuaca and 4,761 m at the Hornocal viewpoint. Along the way you pass through the iconic villages of Purmamarca (with its Cerro de los 7 Colores backdrop), Maimará (with its painter\'s palette hill and famous colourful cemetery), Tilcara (with the restored pre-Inca Pucará fortress), Uquía (with its 17th-century church and "winged angels" colonial paintings), and finally Humahuaca itself (the village that gives the canyon its name). The most dramatic single sight is the Hornocal 14-colour ridge 25 km east of Humahuaca, accessible via a steep gravel road and one of the most photographed landscapes in South America. The Inca Empire used this corridor; so did the Spanish colonists; so did the independence-era armies of General Güemes; today, 250,000+ travellers a year drive RN 9 through one of the most visually stunning landscapes on the continent.

The Villages — Stop by Stop

Purmamarca (km 155 from Salta, 2,200 m)

The first famous village heading north on RN 9. Population ~200. Famous for the Cerro de los 7 Colores — the multicoloured hill that forms the entire backdrop of the village square. The 30-minute Paseo de los Colorados walking circuit at the base of the hill is free and puts you inside the rock formations. Plaza 9 de Julio is the centre — a small adobe square ringed by craft stalls selling textiles, llama-wool sweaters and silver jewellery. Best photography light is at sunrise. Stay one night here to catch it. Recommended hotels: El Manantial del Silencio (luxury, USD 250+), La Comarca (mid, USD 80–150), Hostal Tierra Amarilla (budget, USD 25–40).

Maimará (km 175 from Salta, 2,400 m)

Small village 20 km past Purmamarca, famous for two things: the Paleta del Pintor ("painter\'s palette") hill behind the village — a multicoloured cliff that genuinely looks like splashed paint — and the colourful cemetery on the hillside, where each tomb is painted in vivid blues, yellows and reds. The cemetery is one of the most photographed landscapes in NOA. 15-minute stop. No need to overnight here.

Tilcara (km 195 from Salta, 2,470 m)

The biggest tourist hub of the Quebrada and the best base for 2+ night stays. Population ~5,000. Bohemian, with backpackers, artists, restaurants and folk music in the bars at night. The main attraction is the Pucará de Tilcara, a partially restored pre-Inca fortified settlement on the hill above town — entry USD 5, allow 1.5–2 hours. The Garganta del Diablo waterfall is a 30-minute walk from town. Carnaval in Tilcara (February) is one of the biggest folk celebrations in Argentina. Recommended hotels: Hostal de Zonda, Killa Tilcara Hotel, Patio Alto. Restaurants: El Patio de la Empanada, La Peña de Carlitos.

Uquía (km 215 from Salta, 2,820 m)

Small village famous for the Church of San Francisco de Paula, built 1691, which houses 9 colonial-era oil paintings of the "Ángeles Arcabuceros" — winged angels dressed in 17th-century Spanish military uniforms holding harquebus rifles. These paintings are unique to the Quebrada region and were used to evangelise the indigenous Andean population. Free entry to the church. Quick stop, 30 minutes.

Humahuaca (km 230 from Salta, 2,940 m)

The village that gives the canyon its name, the historical and cultural centre of the region. Population ~11,000. The Plaza Gómez is dominated by the imposing Independence Monument sculpted from local stone. Daily at noon, a mechanical statue of San Francisco Solano emerges from the cabildo to bless the plaza. The 16th-century church is one of the oldest in Argentina. Humahuaca is the base for the Hornocal tour and for the 4-hour drive to Iruya, the remote mountain village hidden in a deep gorge. Restaurants: Aisito, El Portillo, Pacha Manka. Hotels: Solar de la Quebrada, Hostal Posta del Sol.

Hornocal — The 14-Colour Ridge

Hornocal, also called the Serranía de Hornocal or Cerro de los 14 Colores, is the most dramatic single sight in the entire Quebrada — a serrated multicoloured ridge that rises behind Humahuaca, accessible via a 25 km steep gravel road that climbs from Humahuaca (2,940 m) to the viewpoint at 4,761 m altitude. The ridge looks like a multi-layered cake of red, ochre, white, green and pink rock formations stacked in dramatic zig-zag patterns. The road takes 1 h 30 each way; tours from Humahuaca cost USD 35–60 and run morning and afternoon. Best time: 11:00–14:00 when the sun is high enough to light up the colours (early mornings the ridge is in shadow). Bring a windproof jacket — the wind at 4,761 m is brutal. Altitude warning: if you came directly from Salta or sea level the same day, expect headaches and breathlessness; chew coca leaves and don\'t do it on your first day in the region.

Cultural Notes — The 10,000-Year Trade Route

The Quebrada has been a corridor for human movement for 10,000+ years. The Atacama and Omaguaca peoples used it as a north-south trade route between the highland Aymara and Quechua cultures and the lowland Diaguita and Mapuche. The Inca Empire incorporated it into the Qhapaq Ñan (the Inca road system) in the 15th century — fragments of the original Inca road still exist in the cliffs above the modern RN 9. The Spanish colonists built the colonial churches and the postas (way stations) you see today. After independence, General Güemes\' gauchos used the canyon as a base for their guerrilla war against the Spanish royalists. UNESCO inscribed the entire 155 km corridor as a "cultural landscape" — meaning the whole human-shaped canyon is the heritage site, not just individual monuments.

The Carnival of Humahuaca

If you can time your visit, the Carnaval del Norte (February, dates vary with the lunar calendar) is one of the biggest folk celebrations in Argentina. The villages explode with traditional dances, copla singers, brass bands, flour-throwing parades, and the symbolic "burial of the devil" at the end of the week. Tilcara hosts the most famous celebrations. Book accommodation 6+ months in advance. Avoid Carnaval if you don\'t want crowds — it\'s the only time the Quebrada gets truly busy.

Where to Stay
