Ecuador - Cotopaxi Skills Expedition

COVID-19 UPDATE:  AAI has reopened as of June 20, with new policies and procedures for COVID-19. Click the following links to learn more about AAI's COVID-19 Operating Plans and cancellation policy.


We do it all on this trip: Learn or refresh skills with expert instructors, Climb Cotopaxi and Cayambe -- two of Ecuador's most famous volcanoes -- Immerse ourselves in a rich culture, and Take rest days in well-appointed haciendas with good local food.

In addition, for climbers who are still hungry for summits after Cotopaxi, it is possible to extend this trip with a five-day Chimborazo climb, summiting Ecuador's highest peak at 20,703 feet.

In sum, the variety and beauty on this trip are awe-inspiring, and the personal rewards are of such variety and depth that this is commonly one of those experiences that people describe as "a trip of a lifetime." You can also absolutely guarantee that categorization if you add on a five to seven-day boat-based journey through the Galapagos Islands after your climbs. Many who have made ascents with us here have enjoyed ending their Andean journey with a few days in that wonderful archipelago off the coast of Ecuador.

We take a conservative approach to acclimatization, and the wisdom of our itineraries is seen every year in the safety record of our trips and the tremendous success rate of our climbers. We have been guiding the high altitude peaks of Ecuador since 1977, and the days we allocate to acclimatization are based on our decades of experience.

Although in our first trips we allocated nine days for climbing Cayambe and Cotopaxi, for more than two decades we have been climbing on a ten-day itinerary because we found people are much more comfortable at altitude and enjoy a summit success rate slightly over 30% higher than on a nine-day itinerary. You will find other guide services that offer eight and nine-day trips. Our experience tells us that if you subscribed to that pace, you will save a little money and vacation time but cut your summit success rate by 30% - 50%. Climbing at altitude is quite challenging, and it is important to stack the odds for success in your own favor.


Ecuador - Cotopaxi Skills Expedition

Structure and Goals

Part 1: Skills Training and Acclimatization

Exploring and Acclimatizing in Quito (9400 ft / 2865 m)

The Andes of Ecuador run as two parallel and impressive chains of peaks, rising dramatically from Pacific coastal lowlands on the west and even more abruptly from the Amazon Basin on the east. Our flight into Ecuador gives us a grand view of the entire range as we cross the country's northwest coast and pass just over the Pichinchas - 15,700-foot volcanoes standing right above Quito - then drop down to the capital's new Mariscal Sucre International Airport (7907 ft / 2410 m).  It is an exciting entrance into a spectacular country and beautiful city.

Quito is South America's second highest capital (after La Paz, Bolivia), and its high altitude allows us to begin our acclimatization as soon as we arrive. The city fills a gently sloping valley beneath thirteen to fifteen thousand-foot peaks, and from several points just above Quito it is possible to look up and down the "Avenue of the Volcanoes," as the Ecuadorian tourist industry is fond of calling it, and see most of the country's major summits.

The program begins with climbing team members traveling to Ecuador on a Saturday and meeting our lead guide that first evening for dinner. The following morning, we meet for breakfast and then the guides will do an initial program orientation, followed by a thorough gear check.

After the gear check, we head out to explore beautiful Quito, a city of pretty parks and boulevards, a mix of traditional and modern life, and a living incorporation of the structures of South America's colonial past.  In the oldest part of town, cobbled streets with sunken walks are spanned by beautiful stone arches and are overlooked by buildings of 16th and 17th-century architecture.

On our city tour, we explore a variety of Quito’s remarkable architectural sites including La Basílica del Voto Nacional (the largest neo-Gothic basilica in the Americas), La Compania (Quito's most ornate church one of the most significant works of Spanish Baroque architecture in South America, with construction started in 1605), and Church and Monastery of San Francisco, (dating from 1534, the largest historical structure of colonial Latin America).  We visit Quito’s colorful central market where we see a variety of local foods for sale as well as traditional crafts and practical goods for daily life in the city and its surrounding agricultural settlements.

During our time in Quito, we will also visit a local equipment shop and pick up any rental items needed for the Expedition (See the Equipment List for more information regarding rental equipment).

Acclimatization Hikes and Skills Training

Our first acclimatization hike is on 13,776-foot (4199 m) Pasochoa, an extinct volcano about twenty miles south of Quito. Its large, eroded crater opens to the west, and its northwest flanks support a forest like those that once covered the entire Quito basin. We establish a very easy pace on this day hike as we begin to get our bodies used to altitudes above 10,000 feet.

Our second acclimatization hike is on either Rucu Pichincha (15696 ft / 4784 m) or Guagua Pichincha (15,695 ft / 4783 m), depending on conditions. Our primary goal on both of these days is to give our bodies a chance to begin their further adjustment to the altitude while we enjoy some beautiful hiking and outstanding photographic opportunities. These rocky ridges, high grasslands, and summits provide great views of the entire cordillera and an excellent orientation to Ecuador's geography. 

Part 2: Ascent of Cayambe (18,997 ft / 5790 m)

Cayambe is Ecuador's third highest peak. Forty miles northeast of Quito, it stands at 18,997 feet, looking out over Reventador ("The Exploder", one of South America's most consistently active volcanoes) and over the Amazon Basin. Cayambe's glaciers are large and among the most active of all equatorial ice flows, and the varied glacial terrain here provides an excellent training ground and a rewarding summit climb.

Having spent at least seventy-two hours above 9000 feet, group members should be well enough acclimatized to begin sleeping and climbing at greater altitudes. Driving north to the mountain we pass through high, rolling grasslands with wildflowers and occasional herds of sheep and llamas. Leaving paved roads, the track we follow passes several working haciendas, steadily narrows, and becomes more rugged as it climbs higher and higher, finally to reach a point within a half-hour hike of a large stone hut - Ruales Oleas Berge Refuge - that serves as our base on the slopes of Cayambe at 15,290 feet.

As we continue our adjustment to the altitude, we spend our first afternoon and the following day in moderate activity on a low section of the glacier where we work on glacier travel skills, protective systems techniques, and the general procedures we will use in our ascents. The route we will take is not technical, but the number and size of the crevasses make the route serious and the route finding and overall climbing very interesting.

During the glacier skills training, we will cover the following subjects:

  • Crampon technique
  • Principal ice axe positions
  • Roped glacier travel
  • Self-arrest techniques
  • Discussion of high altitude physiology

After skills practice, we will return to the Refuge for a hearty meal and an early night of sleep.

Climbing with headlamps, we leave long before dawn in order to have firm snow conditions throughout the ascent. For the first four hours we make an easy glacier climb to a saddle, and then continue onto steeper and more exciting ground. We traverse around large crevasses, many with enormous tropical icicles hanging from their edges, pass some spectacular seracs, and climb 35-degree slopes with occasional and short, steeper sections as we work our way to the crater rim. The final climb to the summit follows a photogenic line along the glaciated edge of the volcano's crater, a fittingly dramatic ending to an ascent that is varied and scenic throughout.

Part 3: Ascent of Cotopaxi (19,348 ft / 5897 m)

Cotopaxi is the world highest active volcano. It stands in Ecuador's eastern cordillera, towering high above a small altiplano along with three other major peaks within the borders of the beautiful Cotopaxi National Park: Ruminahui (15,602 ft / 4755 m), Sincholagua (16,360 ft / 4986 m), and Quilindana (16,134 ft / 4917 m). Before entering the park, we drive south from Cayambe and stop for a night of rest at a seventeenth-century hacienda, from which we enjoy great mountain views of Illiniza Sur (17,268 ft / 5263 m), Illiniza Norte (16,861 ft / 5139 m), and Cotopaxi.

The next morning we leave the fertile and richly green central valley and drive east into Cotopaxi National Park. We travel through pine forests, then through drier and more open country as we ascend a rugged escarpment and finally reach a small altiplano beneath the park's towering summits. As we make our way up to and across the plain, we are fairly likely to get good sightings of wild horses, llamas, and condors. Following a rather remarkable track in our vehicle, we are able to drive to 15,100 feet, and from there, a forty-five minute climb with full packs takes us to the Josa Ribas Hut on Cotopaxi's flank at 15,729 feet.

On summit day, we again leave long before dawn in order to have firm snow conditions. We first climb non-glaciated slopes and then ascend a series of uniform snow and ice ramps of 30 and 35 degrees to reach a glacial platform at 17,000 feet. As dawn approaches, we enjoy one of the most spectacular color displays in the Andes. Almost every morning, the sun rises over a low trail of clouds which drifts in from the tropical forests of the Amazon Basin. As the sun moves further above the horizon, we are treated to a magnificent array of colors in the clouds, on the multi-hued soils and rock faces of the parkland, and on the massive glacial slopes of 18,714-foot Antisana, which rises to our north.

We belay across occasional snow bridges, skirt large crevasses, and ascend moderate terrain and occasional short steep slopes towards the huge summit cone. We reach the base of the 400-foot rock wall that is called Yanasacha (which means "black wild place" in Quechua), and to its side encounter a gaping bergschrund at the base of the final glacial slopes that we must climb to reach the summit. We traverse out to the far end of the bergschrund, make an easy descent to its floor, and then return to a point below our original position to reach a climbable section of its upper wall. A belayed ten-foot move on steep ice puts us on the 55-degree face, and from there we belay up some of the most enjoyable snow and ice climbing pitches in Ecuador. The gradient eases off as we reach the crater rim, and from there it is an easy ten-minute climb to Ecuador's second highest summit. From the top we enjoy views of nine major equatorial peaks, the seemingly limitless Amazon Basin to our east, and Cotopaxi's spectacular 1000-foot deep summit crater.

Optional Chimborazo Climb Extension 

(20,703 ft / 6310 m)

Many people wish to climb Chimborazo, the highest peak in Ecuador at 20,703 feet (6310 m), and a summit with the further distinction of being furthest from the center of the earth. (Because of the ellipsoid shape of the planet, Chimborazo's location close to the Equator makes it "higher" by this measurement than Mt. Everest.)

Ecuador - Cotopaxi Skills Expedition


"I had a great experience in Ecuador, and enjoyed every minute. The trip was very rewarding regarding beauty and the mountain experiences, but I expected this. What I did not expect were the friendships and relationships that developed between our lead guide, who was a fantastic human being, and the climbers. The guide was a very knowledgeable and experienced guide and I completely trusted him. He was completely committed to the climbers in situations in and out of the mountains, and we traveled effortlessly through his country. The combination of great company and great guiding made this trip a fantastic experience. Thanks AAI!"

Mike Brennan, Scranton, PA

"Not only was my guide technically solid on the mountains, he showed balanced decision making skills on each of the climbs. He did a great job tailoring the trip to our individual needs and abilities."
George Henderson, Harrisburg, PA

"Our expedition was truly an excellent experience. I believe this was due in large part to the character, skill, and personality of our two guides. They were exceptional, made us all feel like we could push ourselves safely, and helped me experience great personal success."
Josh Katzman, Arlington, MA

"AAI is by far the most experienced guide service in the Andes."
