Key information: Cotahuasi and Colca Canyons

    • The Arequipa region in southern Peru is host to some truly astounding geological and geographical formations, not least the Cotahuasi and Colca Canyons.
      • These are claimed to be the two deepest canyons in the world, each over twice the depth of the USA's Grand Canyon and fine specimen of Arequipa's lava-sculpted topography.
        • Independently stunning, the Colca is famed for the huge Andean condors flying high above it; Cotahuasi mixes glaciers with hot spas, juxtaposes millennia-old rock carvings and Spanish gold mines.
          • With each canyon already over 3,000m deep, indomitable mountains can hoist this altitude to nearer 5,000m - and startlingly quickly. The altitude can become a real problem, so come prepared.

WALK SUMMARY

The Cotahuasi and Colca canyons incise deep tracks into Arequipa's arid, altitudinous plateau. They are claimed to be the two deepest canyons in the world, each over twice the depth of the USA's Grand Canyon (although much depends on how you measure canyon depth, a theological and partisan subject), with Cotahuasi having stolen the Colca's prestige in that regard only recently and amidst much wrangle and debate.

 

Volcanic activity from past millennia inscribes huge swathes of Peru's interior. Now, lava-sculpted plains lie high above the riverbeds, against a backdrop of Peru's Andean goliaths.

 

It is through these majestic interior pampas that the respective canyons cut, slicing down through the lava-moulded topography. Trekking down into these astounding canyons penetrates a dramatic, desert wilderness. Their dry, steep walls exhibit improbable Inca terracing in areas, scattering what might otherwise pass for moonscape with flashes of colour and history.

 

Pass amidst dazzling rivers and arid tracts of Andean desert, and through a host of microclimates; from lush, implausible oases in the deepest canyon, to snowfall brought on by the land's relief, much higher up.

 

Looming mountains abut and continue the canyons' precipitous walls, sending potential walking altitude careering upwards. Use these to get level with the huge Andean Condors riding thermals high above.

 

The Cotahuasi and Colca canyons are undoubtedly the most famous of the walks in Arequipa, and justifiably so. Yet the region is rich in wonder throughout:

 

 

Arequipa

 

Arequipa in southwestern Peru runs the whole gamut of pacific coastal resorts and port towns, through to the soaring Andean Peaks that make up South America's spine. Its diversity, therefore, inevitably gives rise to the fantastic and fantastical.

 

Rivers dissect the volcanic lava that moulded these plateaus, and many more canyons provide an incredible contrast to the heights of plateau and mountain. Volcanic cones puncture the skyline, geysers punctuate its scale and serenity.

 

Along Arequipa's pacific border, smaller plateaus and dunes dot microcosms of their grand inland cousins onto the regions coastline.

 

In the province of Castilla, by the town of Corire, is Toro Muerto: 3,000 petroglyphs chronicle Perus human heritage. Near Andaguas: the Valley of Volcanoes, with almost 100 dramatic cones dominating the landscape.

Best times to walk/weather

Best times to walk

This depends on which walk you do. See our Colca Canyon orCotahuasi Canyon pages for more detailed information.

Weather

The weather here is generally very dry and sunny, although humidity, cloud and rain are common between December and April. Owing to the nature of the landscape, the weather can be very variable.

The rainy season lasts throughout January, February and March, whilst temperatures do not alter much over the year. In Arequipa, daily minimums go down slightly from April to November/December, but tend to stay between around 5.5 and 8.8°C. Maximums vary between 21°C and 22°C, no huge difference. However, the ecosystems of the canyons mean that temperatures can vary hugely, whatever the season.

Getting there/transport/permits/fees

Add a comment

Those on organised expeditions are likely to be transported from/to Arequipa, Peru’s second largest city and the region’s capital.

Arequipa is reasonably easy to reach from the larger cities in Peru, with short domestic flights from Lima, Cusco, Tacna or Juliaca. Trains are available from Cusco, Juliaca or Puno, and buses run regularly from Lima and Tacna as well as from cities in Chile and Argentina. However, public transport is not necessarily quick or reliable in South America, so plan carefully.

See our Colca Canyon or Cotahuasi Canyon pages for more detailed information.

Permits are needed to do these walks. They can be obtained on point of entry to the respective canyon area. If part of a group or tour, expedition organisers should arrange these. Permits cost around USD $12.

Guided or independent?

Add a comment

Independent

You can do this walk independently, but you will need to be self-sufficient, so come fully prepared.

Guided/supported

Although shorter walks are generally fine to do independently, most people form or join organised/supported expeditions for the longer ones. If you are very keen to walk on your own then it is possible, although you may need to get a local guide for sections. Be prepared.

Expedition organisers include:

 

Accommodation

The guidebooks have a selection of possible accommodation. The canyons also have a few of hotels and resorts at their respective valley bottoms. Hostelbookers usually has a good selection of cheaper-end accommodation.

Peru has a huge variety of great walks. There is likely to be a good walk within range wherever you may be. We recommend:

  • The Inca Trails, fascinating walks along old Inca trails to ancient ruins, are not far away from here.
  • Many other amazing walks in Peru.

Other activities

You mustn’t miss seeing the centre of Arequipa, which is a UNESCO World Heritage Site due to the excellent preservation of its colonial architecture. Also:

  • Rafting in the canyons
  • Mountain biking
  • Climbing

Shopping, if you must

We are not a shopping website. But, anything bought from local people must be of some help to this poor area. Vendors dot the canyon rims, so wallets out!
