Why Cotopaxi is famous
Cotopaxi is the classic volcano of the Andes: a regular cone with slopes of up to 35°, a base about 20 km across and an ice cap that starts at around 4,900–5,000 m. It is among the highest active volcanoes in the world; the title of the highest is usually given to Ojos del Salado on the Chile–Argentina border, but none of the higher candidates has a record of eruptions like Cotopaxi's. The headline figure of 5,897 m is the one used in Ecuador; the Smithsonian Global Volcanism Program gives 5,911 m.
Ecuador's Geophysical Institute (IG-EPN) counts Cotopaxi among the most dangerous volcanoes on the planet, because of how often it erupts, the ice on its summit and the number of people living along the valleys that drain it. More than 300,000 people live in areas that lahars could reach in an eruption like those of the 18th and 19th centuries. The summit crater measures about 800 by 650 m, and the highest point is on its outer rim on the north side. For climbers, Cotopaxi is the most popular glaciated summit in the country and a common first step towards Chimborazo, Ecuador's highest mountain.
Eruptions: from 1877 to 2022–2023
The IG-EPN lists five great eruptive periods since the Spanish conquest: 1532–1534, 1742–1744, 1766–1768, 1853–1854 and 1877–1880. The worst came on 26 June 1877, when pyroclastic flows melted much of the ice cap and lahars ran more than 100 km down the valleys, towards the Pacific on one side and into the Amazon basin on the other. Latacunga, about 35 km south-west of the summit, was flattened by mudflows in 1768 and again in 1877. A smaller eruption followed in 1903–1904, and minor activity was reported until about 1940.
After 138 years of relative calm, Cotopaxi woke up in 2015. Rising seismicity, gas emissions and swelling of the cone led to explosions on 14 August 2015, with ash clouds that reached Quito's southern districts. The IG-EPN rated this eruption VEI 1 and dates it to the end of November 2015; ash falling mainly to the west hit farms and tourism in Cotopaxi province hard. In October 2022 a new eruptive period began, with small emissions of gas and ash. It lasted until mid-2023, longer than the 2015 eruption, but produced only about half as much ash.
Both episodes closed the summit. After 2015 the ascent stayed closed until 2017. After the 2022–2023 eruption the Ministry of the Environment (MAATE) began a gradual reopening on 21 February 2024, first only for licensed tour operators and registered mountain clubs, and from November 2024 opened the summit to all climbers who meet the park's requirements. As of 2026 the summit can be climbed, but access depends on the IG-EPN's reports and can be closed again at short notice.
Where it is and how to get there
Cotopaxi stands on the Cordillera Oriental (Cordillera Real) of the Ecuadorian Andes, in the province named after it, about 45 km south-east of Quito, 35 km north-east of Latacunga and 70 km north-west of Tena. It belongs to the line of peaks along the Ecuadorian highlands that Alexander von Humboldt called the Avenue of the Volcanoes. Other volcanoes around it include Rumiñahui (4,722 m) to the north-west, Sincholagua (4,873 m) and Quilindaña (4,876 m).
The park lies just east of the Panamericana highway, about two hours by road from Quito and about 40 minutes from Latacunga. From the north the usual approach leaves the highway at Machachi and passes Santa Ana del Pedregal; entry is through the Control Norte or Control Caspi gates. Buses between Quito's Quitumbe terminal and Latacunga can drop passengers at the park turn-off, but there is no public transport inside the park, so most visitors come with a tour, a hired 4WD or a taxi from Machachi. Park gates are open for entry from 08:00 to 16:00. A dirt road climbs past the Limpiopungo lagoon (about 3,850 m) to the car park at about 4,600 m on the north side of the volcano.
The normal route from the José Ribas refuge
The standard ascent follows the north side and usually takes two days. On the first day climbers drive to the car park and walk up a steep sandy track to the José Ribas refuge (also spelled Rivas; 4,864 m), a 45–60 minute climb with full packs. The stone hut was built in 1971, enlarged in 2005 and is run by the mountaineering group of the Colegio San Gabriel in Quito; it provides bunks, meals and hot drinks. Guides normally run a short glacier skills session in the afternoon, followed by an early dinner and a few hours of sleep.
The summit push starts around midnight. The route gains about 1,060 m over 3.4 km. About an hour and a half above the hut, at roughly 5,200 m, climbers reach the glacier, rope up and put on crampons; from there it is typically another five hours across crevassed slopes and up to the crater rim, timed to arrive at first light. The descent by the same route takes about three hours, and teams try to be off the glacier before the sun softens the snow. The route is graded PD (peu difficile): slopes reach up to 50° in places, crevasses may need to be crossed on snow bridges or with ladders, and the line changes from season to season. Since the recent eruptions and continued glacier retreat, guides report more open crevasses than before.
Strong, acclimatised climbers are on top within six to eight hours, but the main challenge is altitude. A climb straight from Quito is possible on paper but rarely succeeds; operators recommend four to five days of acclimatisation first, on lower peaks such as Rumiñahui or Iliniza Norte, with nights in park lodges such as Tambopaxi at about 3,800 m. Required equipment includes mountaineering boots, crampons, ice axe, harness, helmet and rope; since 2024 the park also asks climbers to carry a half-face gas mask with filters for the summit area.
For non-climbers
Many visitors come only for the day. The walk from the car park to the José Ribas refuge is the most popular outing in the park and does not need a guide; some continue a little higher towards the edge of the glacier. Below, trails circle the Limpiopungo lagoon, where condors and gulls are sometimes seen, and mountain-bike tours ride from the car park back down the dirt road. The park also protects the remains of the Inca fortress of Pucará del Salitre, a small visitor centre and campsites.
Permits, costs and rules
Cotopaxi National Park was established in 1975 and is managed by MAATE. Entry to the park itself has traditionally been free; costs come from transport, accommodation and guides. Rules for the summit, as set out by MAATE during the 2024 reopening and confirmed in December 2024:
- a certified high-mountain guide is required for every ascent; independent climbs to the summit are not allowed;
- the ascent must be notified to the park administration in advance (72 hours under the current protocol), usually by the operator or guide;
- climbers need accident or life insurance, an emergency kit and a signed form, and must collect an authorisation wristband at the park entrance;
- the guide registers the group's entry and exit at the gate;
- alcohol and pets are not allowed in the park.
Ecuador's certified mountain guides are trained and represented by the Ecuadorian Mountain Guide Association, ASEGUIM, to international UIAGM/IFMGA standards. Guided two-day climbs are sold by agencies in Quito, Machachi and Latacunga, with Latacunga generally cheaper; prices vary widely with group size and acclimatisation days, so compare what is included (transport, refuge, equipment).
When to go and weather
Cotopaxi lies less than 100 km south of the equator, so there are no summer and winter in the usual sense: temperatures change more between day and night than through the year. In the lower parts of the park daytime highs rarely exceed 20 °C and nights fall below freezing; on the summit night temperatures are well below zero and wind makes them feel colder. The park receives 500–1,500 mm of precipitation a year. Climbs run all year when the volcano is open, but the park recommends July to December for visits.
Water
There is no reliable running water on the route above the car park. The refuge serves hot drinks and meals to its guests; agree with your guide in advance how much water is provided for the summit night, and fill up at the lodges lower in the park. On the climb itself plan on 1.5–2 litres per person in insulated bottles or a thermos, because hoses and plain bottles freeze at night. Lagoons and streams on the páramo are used by animals, so treat or boil any water taken from them.
Mobile coverage and internet
The park lies close to the populated corridor between Quito and Latacunga, and phones may pick up a signal on open ground, but coverage on the volcano is not guaranteed and drops in valleys and on the glacier. Do not rely on a phone as your only link: guides carry radios, and a satellite messenger is worth considering for independent visits to the lower park. The emergency number in Ecuador is 911 (ECU 911); mountain rescue in the high Andes is supported by ASEGUIM's rescue group together with park rangers.
Altitude, dangers and safety
Altitude sickness is the main reason climbers turn back: the hut alone is higher than Mont Blanc's summit. Ascend gradually, drink, and descend if headache, nausea or confusion get worse. On the glacier the hazards are crevasses, icy slopes and cold; the hut sits in a hollow below the ice, and on Easter Sunday 1996 an ice avalanche partly buried it and killed 13 people on the slope above.
Cotopaxi's activity adds its own risks. The IG-EPN warns that climbers near an active crater can meet harmful or even lethal concentrations of volcanic gas, sudden ash emissions and steam explosions. Carbon dioxide can collect in hollows and crevasses, and no mask protects against it, so do not linger on the summit or in sheltered depressions near the crater. Before travelling, check the latest IG-EPN bulletin and MAATE announcements.
History and name
The origin of the name is debated. A widespread explanation reads it as "neck of the moon", from Quechua q'oto (throat) and Aymara phakhsi (moon), because the full moon can appear to rest on the summit like a head; in Kichwa it is often translated as "throne of the moon", while the 18th-century French scientist Charles-Marie de La Condamine recorded it as "shining mass". Andean peoples revered the mountain as a rain-bringer and a home of gods before the Inca conquest, and a local legend says Cotopaxi keeps smoking out of anger because Chimborazo won the love of Mama Tungurahua.
Alexander von Humboldt tried to climb Cotopaxi in 1802 but reached only about 4,500 m, and Moritz Wagner failed in 1858. The first ascent was made on 28 November 1872 by the German geologist Wilhelm Reiss and the Colombian Ángel María Escobar. Reiss's colleague Alphons Stübel reached the top in 1873 with four Ecuadorians, and in 1880 Edward Whymper, with the Italian guides Jean-Antoine and Louis Carrel, made the third recorded ascent and spent a night on the summit during the same expedition on which he made the first ascent of Chimborazo. The painter Rudolf Reschreiter and Hans Meyer climbed it in 1903. The José Ribas refuge, built in 1971, turned Cotopaxi into Ecuador's main mountaineering destination.

- The first permanent seismic station in South America built to watch a volcano was installed on Cotopaxi in 1976.
- Speed records from the refuge: Karl Egloff ran up and down in 1 h 36 min 54 s in 2021, and in January 2026 the American Tyler Andrews lowered the round-trip record to 1 h 21 min 49 s.
- The páramo of the park filters meltwater that supplies part of Quito and is home to wild horses, white-tailed deer, Andean foxes, pumas and spectacled bears.
FAQ
How high is Cotopaxi? 5,897 m, the figure used in Ecuador; the Global Volcanism Program gives 5,911 m. It is the second highest mountain in Ecuador after Chimborazo.
Is Cotopaxi still active, and is it open? Yes, it is active: it erupted in 2015 and again from October 2022 to mid-2023. The summit reopened gradually from February 2024 and to all guided climbers from November 2024. Check the IG-EPN and MAATE before you go.
How long does it take to climb Cotopaxi? The climb itself takes two days: walk up to the José Ribas refuge (4,864 m) on day one, then a summit push from about midnight, roughly 6–8 hours up and 3 hours down. Add four to five days of acclimatisation beforehand.
How difficult is it? Graded PD: a non-technical but serious glacier climb with slopes up to 50°, crevasses and very thin air. Crampons, ice axe, harness, rope and a guide are required.
Do I need a guide or a permit? Yes. Summit climbs require a certified high-mountain guide, advance notice to the park (72 hours under the current protocol), insurance and an authorisation wristband issued at the entrance. Park entry itself has traditionally been free.
Is there water on the way? No reliable source above the car park. The refuge serves hot drinks; carry 1.5–2 litres in insulated bottles for the summit night.
Is there mobile phone coverage? Sometimes on open ground near the refuge, but not reliably on the volcano. Guides carry radios; the emergency number is 911.
When is the best time to climb Cotopaxi? It can be climbed all year when open; the park recommends July to December for visits. Climbers start around midnight to be on top at sunrise.
Can I visit without climbing? Yes. The walk from the 4,600 m car park to the refuge takes under an hour, and the Limpiopungo lagoon and the Inca ruins of Pucará del Salitre are easy outings.
