04:30 h — Hotel pickup in Cusco. Private vehicle southeast toward Ocongate, following the Interoceánica Sur highway (Route 26) through the Vilcanota Valley. The drive passes through Urcos (3,100m), Cusipata, and Ocongate before the final ascent to Tinki and Pacchanta — approximately 3 hours.
~07:30 h — Pacchanta (3,990m). Breakfast at the community. The Pacchanta community is a traditional herding settlement at the foot of Ausangate, inhabited by Quechua-speaking families whose principal activity is camelid herding (alpacas and llamas). The corrals, the stone-and-adobe houses, and the community structure are largely unchanged from pre-Columbian patterns, adapted to centuries of contact with the colonial and republican state.
~08:00 h — Lagoon circuit begins. The same route covered in the 7 Ausangate Lagoons day tour: Otorongo Macho (4,450m) → Otorongo Hembra (4,500m) → Puca Cocha (4,550m, "Red Lake") → Alqa Cocha (4,600m) → Qomer Cocha (4,650m, "Green Lake") → Azul Cocha (4,700m, "Blue Lake") → Pata Cocha (4,750m, "Upper Lake"). Total circuit: ~10 km, ~3.5 hours.
The seven lagoons are fed by direct meltwater from the Ausangate glacier — the permanent icefield visible from all points on the circuit. Each lake's color reflects its mineral content: iron oxide (red), glacial chlorite (green), suspended glacial flour (turquoise), and clear snowmelt through deep bedrock (blue). The sequence changes color through the day as the sun angle shifts.
Fauna: vicuñas are consistently present in the lower puna around Otorongo Macho and Hembra. Andean condors circle above the upper lagoons in the mid-morning thermal period. Alpacas from the Pacchanta community graze near the trail throughout. Parihuanas (Andean flamingos) are occasionally seen in the shallower margins of Alqa Cocha.
~12:00 h — Lunch at Pata Cocha or near the upper lagoon area. Hot meal prepared by the camp cook.
~13:00 h — Continue northeast across the puna above the lagoon basin toward the high camp. This section is off the standard day-tour route — the trail climbs from the Pata Cocha area toward a sheltered valley at approximately 4,700m, between the Ausangate massif and the ridge that connects to the Vinicunca approach. Distance: approximately 3 km, ~1 hour of walking.
~14:30 h — High camp (4,700m). The porter team has arrived ahead of the group with tents erected. The campsite is in a high puna valley with views toward Ausangate to the north and the ridgeline above Vinicunca to the west. Wind and temperature drop rapidly after sunset; tents are double-walled, sleeping bags are rated to -15°C, and the camp cook prepares a full hot dinner.
~18:00 h — Dinner at camp. The guide gives a briefing on tomorrow's route, timing, and acclimatization reminders. Early sleep is recommended — the next morning begins at first light.
Camp night 1: High camp (~4,700m)
