What you're really signing up for.

"The highest you can stand near Mexico City and still be home for dinner. A bucket-list day in its own right — and real acclimatization if Pico is next."

The Refugio de los Cien (the "100" refuge) is the first hut on the standard route up Iztaccíhuatl, sitting around 4,780m on the mountain's shoulder. We drive you from Mexico City to La Joya (≈3,950m), the trailhead above Paso de Cortés, and hike up to the refuge and back — roughly 7km round trip with about 830m of gain.

There's no glacier, no rope, no midnight start. What there is: real high altitude and a view most people never get. Plenty of climbers do it purely for the day — it's the most spectacular high-altitude hike within reach of Mexico City. It also works as honest acclimatization before Pico de Orizaba: a separate mountain, so the hours above 4,500m are genuine prep, not a repeat.

It also stands on its own as one of the most dramatic day-hikes in central Mexico. Popocatépetl sits directly across the pass, often venting gas and ash, and the Izta massif rises above you. You'll feel the altitude on the final climb to the hut — that's the point. Come having spent a day or two in Mexico City and most hikers reach the refuge comfortably.

What to bring, what we provide.

This is a high-altitude day hike — standard hiking gear, no glacier kit. The altitude and the wind on the ridge are the variables, so layers and sun protection matter most. Need to rent personal items? We'll arrange it.

"Cristino is the best, most experienced guide you could ask for."

We had an amazing time. Cristino goes above and beyond — just a genuinely warm person. Super well-organised: transport, food, technical gear. Everything is arranged perfectly. We would definitely do it again.

"Knowledgeable, friendly, and funny — the best guide we could have wished for."

The company was always very quick to respond to all my questions, and helped me with everything I needed. Our guide was the best we could have wished for: knowledgeable, friendly, and funny. He knows lots about the history of Mexico.

"They took great care of us and motivated us the whole way."

Cristino took great care of us, helping set up tents, cooked, and more importantly motivated us even when we felt discouraged halfway. Wonderful experience overall. I would recommend doing it with this company.

Where this hike fits.

A standalone high-altitude day — and honest acclimatization for Pico de Orizaba (05). It's not a stepping-stone to the Izta summit (04): that's a separate 2-day climb that already covers this ground, so most people pick one or the other. Here's how the family fits.

Pricing.

Most Refugio hikes run 2–4 climbers. Bigger groups get the same rate at 3 and above.

Deposit — 35% secures your guide and date.

Balance — 65% due at the END of your trip.

The questions everyone asks.

No — this is the day hike to the Refugio de los Cien at about 4,780m, the first hut on the Izta route. There's no glacier, no rope, and no summit push. The full Iztaccíhuatl summit (5,230m) is a separate 2-day expedition. Most people do this hike for its own sake, or to acclimatize for Pico — not as a warm-up for the Izta summit itself.
Moderate. About 7km round trip with roughly 830m of elevation gain over 5–7 hours. No technical skills required, but the whole hike is above 3,900m and the final pull to the refuge is where you feel the thin air. Solid hiking fitness and a day or two acclimatizing in Mexico City make a big difference.
Honestly, no — if the Izta summit is your goal, you'll hike this exact lower section on summit day, so doing it first just repeats the ground. Go straight to the 2-day expedition. Where this hike shines is as a spectacular standalone day, or as acclimatization before Pico de Orizaba — a different mountain, where the time at altitude is real prep.
No technical or mountaineering experience required. You should have solid hiking fitness and ideally some time at altitude. If this is your first mountain in Mexico, expect to feel the altitude on the upper section — that's normal and exactly what acclimatization is for.
Popocatépetl is an active volcano directly across the pass — part of what makes this hike spectacular. Iztaccíhuatl is a separate, dormant mountain, and the park manages access based on Popo's alert level. Your guide confirms park access and the current alert the morning of your hike, and we don't go if conditions aren't right.
Real concern above 4,000m. Spend at least 1–2 days in CDMX (2,250m) before. The refuge at 4,780m is where many hikers first feel real altitude effects. Tell your guide immediately if you feel a headache, nausea, or dizziness — the hike is short enough that descent is always quick if needed.
Year-round. November through March offers the most stable weather and clearest views of Popo and the valley. Rainy season (June–September) brings afternoon cloud and storms, so we start early and watch the sky.
Yes. Tell us when you book what you need — boots, jacket, gloves, daypack — and we'll arrange rentals through our partners in CDMX. Reserve 7+ days out so sizing works. We provide trekking poles at no charge.
Maximum 4:1 hiker-to-guide ratio. Most groups are 2–6 people total. Smaller groups mean a faster pace and more attention from your guide.
