The Iliniza is a stratovolcano in the southwest of Quito. It has two snow-capped peaks, the South Illiniza (5,248 m) and the North Illiniza (5,126 m). During this trip, we'll climb the first one. Its ascent is more difficult than the northern peak due to its glacial nature. The route has intermediate-advanced difficulty steps and after some occasional snowfall, we may need to use rope and crampons.

I think that the South Illiniza is one of the best acclimatization mountains in Ecuador. You can use it as a preparatory ascent for higher peaks such as the Cotopaxi, Chimborazo and Cayambe. In addition, we will spend some nights in a rustic hut which is between the two peaks. We'll reach there from El Chaupi.

As for the Antisana, it is the fourth highest volcano in Ecuador. It lies inside an important natural reserve, where the native fauna and flora abounds. We can find many species of birds here, among them, the hummingbirds and the frailejones. Its summit has a glacier and we can access there from the city of Quito.

I think it is a great opportunity to climb two summits in only one trip. If you are planning to come to Ecuador, don't miss this chance! Contact me now for more details and make your reservation.

And finally, we will continue to the summit of Rucu Pichincha at 4696 m. The crossing of this route is very interesting because of its nature and geography with several summits and landscapes. It is a perfect acclimatization process to continue with the plan to climb the Antisana summit. After making the 3 summits we will go directly down to the cable car for 2-3 hours to the base of the mountain where we will take a car to the hotel Sierra Madre (B/BL).

We will wake up at 3 AM, have breakfast, check the equipment and leave the hut at 4 AM. So, we will start hiking up on a moderated terrain until we reach a section of rock climbing. After that we have reached the glacier. This section has steep ice/snow technical slopes and some crevasses depending on the snow conditions. We may need to use ice axes, crampons and helmet. The difficulty of this peak can increase or decrease depending on the presence or lack of ice or snow.

Once at the summit we will have a rest, eat and take many pictures. After recovering your energy we will start descending by the same way. The round trip will take 9 hours. Arrival at hut, rest, packing of the gear and moving down to the parking lot. We will then drive to La Ciénega, where we’ll arrive at 4 – 5 PM (B/BL).

What people are saying about Reynaldo



Had an amazing time with my guide Ramiro. He selected the perfect mix of mountains in order to properly acclimatize so I could achieve the summit of Cayambe. With his vast experience of more than three decades he was able to teach me a lot of skills and know-how along the way so I’d always feel safe on the mountains. I can only recommend a trip with Ramiro. You’re definitely in good hands and going to make wonderful experiences.
