Quebrada de Humahuaca: Visitor and Heritage Guide

The Quebrada de Humahuaca is a narrow and arid mountainous valley in the Province of Jujuy, in the northwesternmost part of Argentina. It is flanked by the high plateau of the Puna on one side and the eastern wooded areas on the other, and it follows the Rio Grande from its source in the cold high desert plateau of the High Andean lands some 150 kilometers south to its confluence with the Rio Leone.

UNESCO inscribed it in 2003 under criteria (ii), (iv) and (v). The property covers 172,116 hectares, with a buffer zone larger again.

Why it is inscribed

Not for the rock, although the banded color of the valley walls is what fills the photographs. It is inscribed as a cultural landscape, for substantial evidence of its use as a major trade route over the past 10,000 years.

Three layers of that are visible to an ordinary visitor.

• Prehistoric hunter gatherer communities, whose traces are the oldest thing in the valley.
• The Inca Empire, in the fifteenth and sixteenth centuries, for whom this was a section of a road system that ran the length of the Andes.
• The fight for independence, in the nineteenth and twentieth centuries. The valley was a corridor for armies for the same reason it had been one for traders.

The point is the continuity rather than any single monument. The same line through the mountains has been the practical way north and south for longer than most countries have existed.

Visiting

The valley is normally traveled from south to north from Jujuy, stopping in the villages strung along it. Purmamarca, Tilcara and Humahuaca itself are the usual stops. Each is small, and the pleasure of the place is in slowing down rather than in covering all of them.

Markets, adobe churches and the pre Hispanic sites above the villages are the substance of a visit. Carnival here is one of the strongest living traditions in Argentina, and the festivals guide covers it.

Altitude is the planning constraint

This is high country, and the valley climbs as it runs north. Altitude sickness is a risk in this region. Acclimatize before you walk high, never during. Give the northwest a full day before you attempt anything strenuous, and treat the first day as part of the itinerary rather than as dead time.

The practical measures are unglamorous and they work. Arrive and rest. Drink considerably more water than you would at home, because the air is thin and very dry. Eat lightly on the first day and go easy on alcohol. Ascend gradually where the route allows it.

This page publishes no medication and no dose. Whether to take anything, and what, is a conversation with your own clinician, who knows your history, and it is worth having before you fly rather than in a pharmacy at altitude.

When to go

The dry part of the year, roughly April through October. The summer rains fall between December and March and can close roads in a valley with one road through it. The daily temperature range is large in every season: a warm bright afternoon becomes a genuinely cold night. The weather guide sets that out.

Sun protection is not optional here. The air is thin and dry and the light is direct. A wide brimmed hat, sunscreen and sunglasses do more for your comfort than any other item in the bag.

On health geography, note that the yellow fever vaccine is generally not recommended for designated areas of Jujuy, and it is not an entry requirement for Argentina. It is recommended for Corrientes and Misiones Provinces, which are a different part of the country entirely. Raise your own itinerary with a travel clinic ideally eight weeks before departure.

Verify Before You Travel

Road conditions in the Quebrada are seasonal and the summer rains genuinely close them. Confirm the heritage position with the UNESCO World Heritage Centre record for the Quebrada de Humahuaca, and check current road status locally before committing to a driving itinerary.
