Of the three volcanoes surrounding Arequipa, Pichu Pichu is the one that appears least often in the city’s tourist photographs and the one few travelers know by name. Misti draws attention because of its almost perfect cone and its visibility from nearly every point in the historic center. Chachani impresses with its 6,057-meter height and its status as an accessible six-thousander. Pichu Pichu, southeast of the city, has a longer and more complex silhouette, with several summits instead of a single dominant peak, and is partially hidden from the city’s most popular viewpoints. That secondary position in the tourist landscape contrasts with its historical importance: it is the oldest volcano of the three, has archaeological evidence of Inca ceremonies at its summit, and offers a completely different ascent from Misti or Chachani in terms of scenery, solitude, and the overall character of the experience.

Geology: the oldest of the three
Pichu Pichu is an extinct volcano. Its last eruption occurred millions of years ago, making it the oldest volcano among Arequipa’s three guardians and the only one in the trilogy that geologists classify as definitively inactive. It emits no fumaroles, is not under volcanic emergency monitoring, and has no eruptive history during the historical or late pre-Hispanic periods.
The Pichu Pichu volcanic system does not have the symmetry of Misti or the broad extension of Chachani, but rather an elongated east-to-west structure with up to seven summits of different heights. The main summit, called El Coronado, reaches 5,664 meters above sea level. The other summits of the system have lower elevations distributed along the massif’s ridge. The Quechua name, Pichu Pichu, literally translates as peak peak or summit summit, directly referring to the multiple peaks that define its silhouette when viewed from the city. From the Carmen Alto Viewpoint in the Cayma district, visitors have the best panoramic view of the entire massif from Arequipa.
History and archaeology: mummies at the summit
Like Misti and Chachani, Pichu Pichu was a sacred Apu for the cultures that inhabited the Chili Valley before and during the Inca Empire. In the Andean worldview, volcanoes were not geographical accidents but living beings with their own will, capable of protecting or punishing the communities living on their slopes. This sacred condition required communities to maintain a reciprocal relationship with the volcano through offerings and regular ceremonies.
In 1965, an expedition found the skull of a young girl at the summit of Pichu Pichu alongside gold, silver, and ceramic objects, giving the volcano the same archaeological status as Misti and Ampato. Three decades later, during excavations carried out in 1996 with the participation of local guides and specialized archaeologists, three Inca mummies were discovered near the summit along with remains of a ceremonial platform where rituals were performed. One of these mummies is displayed at the José María Morante Archaeological Museum of the National University of San Agustín in Arequipa. The textiles, pottery, and metal objects accompanying the mummies are part of the same museum’s collection.
That ceremonial platform at the summit, identified by archaeologists as the place where offerings and capacocha rituals were carried out, is one of the most unique aspects of the Pichu Pichu ascent: this is not a volcano climbed only for the scenery, but one whose destination carries a historical significance that Chachani, despite all its visual spectacle, does not offer in quite the same way.
The name and the legend
Besides the literal translation of peak peak or summit summit, the name Pichu Pichu has an alternative story in Arequipa’s oral tradition. The most widespread legend among locals says that before humanity existed, the Pichu Pichu volcano fell in love with its neighbor Chachani. The gods did not approve of this union and, to separate them, placed a tall and impenetrable soldier between the two: the Misti volcano. The image of the three volcanoes as a triangle of frustrated love turned into stone is one of the most beloved narratives of Arequipa’s identity, even though its origin is clearly post-Spanish conquest.
Pichu Pichu is also called the Sleeping Indian in some texts because of the shape formed by the ridge of its summits when viewed from certain angles, which some associate with the silhouette of a reclining human face. Like all figures projected onto mountains by collective imagination, this visual interpretation changes depending on where it is viewed from and with what perspective one arrives.
The ascent: solitary and archaeological
The ascent to Pichu Pichu is fundamentally different from Misti or Chachani in both character and experience. It does not have the tourist infrastructure of the other two volcanoes, does not receive the number of visitors who climb Misti each week, and lacks the reputation of an accessible six-thousander that attracts international mountaineers to Chachani. What it does offer is a volcanic highland landscape where the chances of encountering other climbing groups are minimal, a route that passes through Laguna Salinas before reaching the volcano’s slopes, and a summit destination featuring the Inca ceremonial platform and panoramic views over the Volcanic Cordillera of southern Peru.
The standard format is two days and one night. On the first day, the vehicle transfer from Arequipa passes through Laguna Salinas at 4,300 meters, where during certain times of the year there are colonies of pink flamingos, varieties of Andean ducks, and high-altitude gulls that make the journey an additional experience before reaching base camp. Camp is set up on the slopes of the volcano, and the night at that altitude precedes the second day’s ascent.
On the second day, the ascent to El Coronado summit at 5,664 meters takes approximately four hours from camp. The terrain is less demanding than Misti’s final ash section, but the altitude and cold create a similar level of effort. At the summit, the Inca ceremonial platform, the remains of stone structures, and the views over Misti, Chachani, and the Andean highlands stretching toward Laguna Salinas are the reward for an ascent that offers a historical dimension no other volcano in Arequipa can provide at the exact point of arrival.
The descent back to camp takes between one and a half and two hours. The return drive to Arequipa passes through the town of Chiguata and its agricultural countryside. Total travel time back to the city from camp is between two and three hours.
Laguna Salinas and the wildlife of the highlands
Access to Pichu Pichu passes through Laguna Salinas, a high-altitude salt lake at 4,300 meters that forms part of the Salinas and Aguada Blanca National Reserve alongside Chachani and Misti. Between November and February, when pink flamingos arrive at the lake to breed, the lagoon presents a completely unexpected visual scene for those unfamiliar with it: thousands of pink birds across the water with volcanoes in the background. During the rest of the year, the lagoon is home to Andean aquatic birds, vicuñas, and guanacos in the surrounding wetlands.
This combination of highland wildlife along the access route and Inca archaeology at the summit makes the ascent to Pichu Pichu an experience with more layers than most volcanic ascents in the region.
Who Pichu Pichu is for
Pichu Pichu is especially worthwhile for travelers who have already seen Misti from the city or climbed it, have more than two days in Arequipa, and want a mountain experience that combines archaeological history with volcanic scenery without the relative crowds of the other two volcanoes. It is not the most visually spectacular volcano nor the most physically demanding in terms of difficulty. It is the most solitary, the oldest, and the one with the densest archaeological record at its summit. For travelers who value those characteristics over altitude or destination popularity, Pichu Pichu is the most coherent choice among the three.
