Iliniza Norte 5,126 m · Sur 5,245 m
Climbing Iliniza Norte & Sur
Twin summits south of Quito: one a rugged scramble, the other a serious glacier climb. Iliniza Norte is Ecuador's classic acclimatization peak, and Iliniza Sur is a technical alpine test.
Norte or Sur: which Iliniza is for you?
The Ilinizas are twin peaks south of Quito, the eroded remains of a single ancient volcano now split into two very different climbs. Iliniza Norte (5,126 m) is a non-technical scramble. It is steep and exposed in places (the 'Paso de la Muerte'), but a fit hiker needs no glacier gear and no ropes. Iliniza Sur (5,245 m) is a glaciated, technical alpine climb with steep ice that demands mountaineering skill.
That contrast is why the Ilinizas matter. Iliniza Norte is the best acclimatization climb in Ecuador, the step most successful climbers take before Cotopaxi or Chimborazo. Climb Norte to test your legs at altitude. Take on Sur when you're ready for ice and exposure.
Why we climb Iliniza Norte before Cotopaxi
We see climbers rush straight to Cotopaxi and get turned around by altitude. Iliniza Norte fixes that. A non-technical 5,100 m scramble is a good test: if you handle Norte well, you're ready for the big glaciated summits. We build it into almost every Cotopaxi and Chimborazo program for this reason. It raises your summit odds more than any gym session can.
Your itinerary
Iliniza Norte (2-day scramble)
Drive to El Chaupi and hike up through páramo and vicuña country to the Nuevos Horizontes refuge (4,750 m). Skills review and an early night.
An early start for the scramble to the 5,126 m summit, including the exposed 'Paso de la Muerte' ridge with your guide. Summit views across to Cotopaxi, then descend and return to Quito.
Iliniza Sur (technical, for experienced climbers)
To the refuge as above, with a focused session on ice technique, rope work and crampon skills for the glaciated south face.
A pre-dawn start onto the glacier, with steep ice and alpine terrain to the 5,245 m summit of Iliniza Sur, then a careful roped descent. It is harder than Cotopaxi.
Where the Ilinizas sit on the acclimatization ladder
Iliniza Norte slots neatly between the day-hikes around Quito and the big glaciated volcanoes, as the last step before a summit attempt:
- Quito: 2,850 m
- Pasochoa: 4,200 m
- Refuge: 4,750 m
- Iliniza Norte: 5,126 m
- Cotopaxi (next): 5,897 m

Ilinizas climbing FAQ
How hard is Iliniza Norte?
Iliniza Norte is a challenging but non-technical scramble. A fit hiker needs no glacier gear and no ropes, though the upper ridge (the 'Paso de la Muerte') is exposed and your guide protects the moves there. The main demand is altitude and steep, loose terrain. It's a big step up from a normal day hike, and a good one to take before Cotopaxi.
What's the difference between Iliniza Norte and Sur?
Norte (5,126 m) is a non-technical scramble; Sur (5,245 m) is a glaciated, technical alpine climb with steep ice that requires mountaineering experience and rope skills. Most people climb Norte as acclimatization; Sur is for experienced climbers wanting a serious challenge.
Is Iliniza Norte good acclimatization for Cotopaxi?
It's the best there is. At 5,126 m and non-technical, Iliniza Norte lets your body adapt to high altitude and tests your fitness without the glacier. That is the preparation that raises your Cotopaxi and Chimborazo summit success.
Do I need experience to climb the Ilinizas?
For Norte, no prior mountaineering experience is required, only good hiking fitness and a head for some exposure. Iliniza Sur is different: it needs glacier and ice-climbing skills, which we can teach and build up to over a longer program.
How many days do you need for the Ilinizas?
We run the Ilinizas as a 2-day climb with a refuge night. Many climbers combine Iliniza Norte with a Cotopaxi or Chimborazo program as the acclimatization stage of a longer multi-day expedition.
When is the best time to climb the Ilinizas?
December–January and June–September offer the most stable conditions. Iliniza Sur's glacier is especially condition-dependent, so we watch the weather closely and will advise the best window for your dates.
