Description

Illampu (6,368 m) is the northernmost of the great peaks of Bolivia's Cordillera Real, rising directly above the small town of Sorata on the north-eastern edge of Lake Titicaca. Bolivia's fourth-highest summit, it is not a volcano but a granite–metamorphic massif thrown up by Andean orogeny. Its summit was first reached on 7 June 1928 by German alpinists Hans Pfann, Alfred Horeschowsky and Hugo Hörtnagl together with Erwin Hein of Austria. Illampu is widely regarded as the hardest 6,000 m peak in Bolivia—even its easiest line is graded AD with snow slopes to 65°—and is often paired with its neighbour Ancohuma as one massif. For the Aymara people, Illampu is a sacred guardian mountain of the Sorata region.

Routes

Pendekatan Cocoyo (sisi utara/timur) dengan llama

AD+ / D — glasier & es teknis

6 hari

An alternative approach via the village of Cocoyo (~5 hours by jeep from Sorata). At Cocoyo, expedition loads are carried by llamas (~12 kg each) up to a high base camp. This approach serves Illampu as well as combined Illampu–Ancohuma expeditions and tends to be longer and more technical than the direct Laguna Glaciar approach.

Rute Normal — Punggungan Barat Daya (SW Ridge) via Sorata

AD (Fairly Difficult) — lereng salju/es hingga 65°

5–6 hari (pulang-pergi dari Sorata)

Illampu's standard and 'easiest' line, though still technical. From Sorata (2,680 m) the approach climbs to Laguna Glaciar (~5,040 m) as base camp, then a high camp on the glacier. Summit day takes the ~300 m Northwest Headwall (60°) to the saddle between Illampu and Huayna Illampu, then follows the broad but exposed Southwest Ridge (30–40°) with a very steep, exposed final section (~65°) to the top (6,368 m). Crampons, ice axe, rope and solid acclimatisation are essential.

Route Segments

1

Sorata (2.680 m) → Laguna Glaciar / Base Camp (5.040 m)

5.040 mdpl

Pendekatan 1–2 hari; base camp di tepi danau glasial.
2

Base Camp → High Camp (di glasier)

Perpindahan kamp tinggi di atas glasier untuk mempersingkat hari puncak.
3

High Camp → Saddle Illampu–Huayna Illampu (via Northwest Headwall 60°)

⏱ 2–3 jam

Dinding es ±300 m sebelum mencapai sadel.
4

Saddle → Puncak Illampu (6.368 m) via SW Ridge

⏱ 3–5 jam 6.368 mdpl

Punggungan 30–40° yang terekspos; ±80 m terakhir sangat curam/terekspos (65°).

Climbing Experiences

Illampu (6,368 m) above Sorata is known as Bolivia's hardest 6,000 m peak. Climbers share two kinds of experience: (1) a technical summit push via the Southwest Ridge (AD), with steep ice and an exposed summit ridge—usually 5–6 days round-trip from Sorata; and (2) the Illampu Circuit trek, a multi-day route (~5–7 days, roughly 80 km) around the Illampu–Ancohuma massif through Aymara villages, high passes and glacial lakes. The videos and reports below reflect both sides—from an alpine expedition to the more accessible circuit trek.
