Cotopaxi volcano

Volcán Cotopaxi

Information

Elevation: 5.897 m
Country: Ecuador (EC)
Location / Range: Cordillera Central (Eastern Andes), Cotopaxi Province, Ecuador — within Cotopaxi National Park
Mountain type: Active stratovolcano
Volcanic?: Yes — volcano
Coordinates: -0.6806, -78.4378
Difficulty: Moderate–strenuous (Alpine PD grade; glacier climbing with crampons and ice axe, rope not always required; non-technical but requires acclimatization above 5,000 m; volcanic activity status is monitored)
Best Season: June–September and December–February (Ecuador's dry season; avoid the rainy February–May and October–November)
Permits & Rules: Parque Nacional Cotopaxi entrance ticket (~$10 USD for non-residents, ~$2 USD for Ecuadorian residents) paid at the park entrance; climbing permit from the Ministerio del Ambiente (available in Latacunga or at the park ranger station); an ASEGUIM guide is strongly recommended; visitors must keep their receipts
Hazards: Active volcanic activity (eruptions/pyroclastic flows, SO₂ gas)—the summit was closed October 2022–March 2024 due to an eruption; crevasses on the shrinking glacier; altitude sickness above 5,000 m; very cold temperatures at night; ice/snow conditions vary by season

Description

Cotopaxi (5,897 m) is one of the world's highest active stratovolcanoes and Ecuador's most iconic summit, rising symmetrically from the Andes plateau within Cotopaxi National Park. Its glaciated cone is visible from Quito on clear days. The standard ascent departs at midnight from Refugio José Rivas (4,864 m), ascending the northern glacier with crampons and ice axe to the active crater rim — a non-technical route taking 6–8 hours to summit. After a closure due to volcanic activity (October 2022–March 2024), the peak reopened for climbing. Solid acclimatisation at 3,500–4,500 m for at least two nights before summit day is strongly advised. Volcanic status is monitored by Ecuador's Geophysical Institute (IG-EPN) and must be checked before any attempt.

Routes

Ruta Yanasacha — Sisi Barat (Teknis, Jarang Dilakukan)

Sangat berat (D; es & batuan teknis)

+1500 m 2–3 hari

A technical line via the western flank involving basalt rock and steep glacier near the Yanasacha wall. Extremely rarely attempted and requires advanced ice/rock climbing skills, full technical equipment, and an experienced guide. Not suitable for recreational climbers; this is an alpinist objective for specialist expeditions only.

Rute Normal — Sisi Utara (via Refugio José Rivas)

Sedang–Berat (PD)

+1033 m 1–2 hari (summit attack ~6–8 jam dari refugio, turun ~2–3 jam)

The standard route attempted by nearly 99% of climbers: overnight at Refugio José Rivas (4,864 m), midnight departure, north-face glacier ascent with crampons and ice axe, past crevasses and seracs to the active crater rim. Summit push 6–8 hours; descent 2–3 hours. Non-technical in normal conditions but requires solid acclimatisation and current volcanic status check from IG-EPN.

Safety Statistics

Moderate risk

Aggregated for prevention and awareness — not a casualty list. Read alongside the safety tips below.

Indicative — small sample size.

· No structured fatality statistics (a death rate per number of ascents) are published for Cotopaxi, so the figures are indicative — not an official rate. The deadliest recorded climbing accident was the 1996 avalanche that killed 13 people around the José Rivas Refuge (~4,800 m); informal estimates suggest roughly 1–2 climber deaths per year. The main hazards are avalanche and icefall on the glacier slopes (notably below the Yanasacha rock wall), crevasse falls on the summit route, altitude illness at 5,897 m, plus the mountain's active-volcano status — eruptions in 1877, 2015, and 2022 triggered national-park closures.

Causes of death

Avalanche est.

💡 Avalanche on the glacier slopes is Cotopaxi's deadliest objective hazard — the 1996 tragedy near the refuge showed this, and earthquakes can weaken the glacier above. Check snow conditions, avoid loaded slopes after storms or midday warming, cross hazard zones (e.g. below Yanasacha) in the pre-dawn cold while the ice is frozen, and never camp or rest long beneath ice walls.

Crevasse fall est.

💡 The summit route crosses a crevassed glacier, some spans hidden under fragile snow bridges. Always travel roped, use crampons and an ice axe, know crevasse-rescue technique, and start pre-dawn when snow bridges are strongest.
Source
Altitude illness (AMS/HACE/HAPE) est.

💡 The 5,897 m summit is reached on a short push from the refuge, so altitude illness often strikes climbers who arrive under-acclimatised. Acclimatise gradually beforehand, stay hydrated, and descend immediately if HACE/HAPE symptoms appear.

Other est.

💡 Cotopaxi is an active, glacier-clad volcano; eruptions can trigger large lahars and close the park (2015, 2022). Monitor the Instituto Geofísico (IG-EPN) and park-authority status before setting out, and do not climb when the activity level is raised.

Notable incidents

1877 1877 eruption & lahars — more than 400 deaths

On 26 June 1877 a Cotopaxi eruption melted its glacier cap and unleashed lahars that flowed ~325 km to the Pacific in under 18 hours, destroying settlements in the surrounding valleys. An evidence-based re-examination (2024) estimates more than 400 fatalities, while popular sources sometimes cite higher figures (~1,000). The event is a reminder that the greatest hazard of a glacier-clad volcano is lahars that can reach far from the summit.
Source
1996 1996 refuge avalanche — 13 deaths

An avalanche killed 13 people around the José F. Rivas Refuge (~4,800 m) when part of the building was buried; an earthquake a few days earlier is thought to have weakened the glacier above. It is the deadliest recorded climbing accident on Cotopaxi and underscores the danger of camping or resting in an avalanche-exposed zone.

2015 2015 volcanic unrest & park closure

An eruption that began in August 2015 forced the closure of Cotopaxi National Park; the government estimated hundreds of thousands of people at risk from potential lahars, and the mountain only reopened to climbing in October 2017. The episode shows that access to an active volcano can be closed at any time for safety.
Source
2022 2022 renewed eruption & climbing restrictions

Renewed volcanic activity that began in October 2022 again temporarily closed the park and restricted climbing, with thousands of earthquakes recorded during the unrest. Climbers must check the latest protocols and status before planning a Cotopaxi ascent.
