How to Conquer the Ausangate Trek in Just 4 Days

High in the Peruvian Andes lies one of South America's most breathtaking and lesser-known hikes — the Ausangate Trek. Towering peaks, turquoise alpine lakes, remote Andean villages, and the vibrant Rainbow Mountain all await adventurers who take on this high-altitude journey. While the traditional Ausangate circuit typically takes 5 to 6 days, it’s absolutely possible to conquer the Ausangate Trek in just 4 days — with the right planning and preparation.

Here’s everything you need to know to take on this epic trek in a shorter but just as rewarding time frame.

Why Choose the 4-Day Ausangate Trek?

If you’re short on time but still want an unforgettable Andean adventure, the 4-day version of the Ausangate Trek offers a condensed but intense experience. It hits all the highlights: glacial valleys, hot springs, the stunning Rainbow Mountain (Vinicunca), and jaw-dropping views of the 6,384-meter Ausangate peak.

You’ll cover roughly 40–45 kilometers (25–28 miles) over four days, often hiking at altitudes of 4,000–5,100 meters (13,000–16,700 feet). It’s not an easy trek — but it’s worth every step.

Trek Overview: 4-Day Itinerary

Here’s a sample 4-day itinerary to help you visualize the journey:

Day 1: Cusco – Tinki – Upis

Drive Time: ~3.5 hours from Cusco to Tinki

Hiking Distance: 7–9 km

Camp: Upis (4,400m) near hot springs

After an early morning departure from Cusco, you’ll drive to the trailhead near the village of Tinki. The first day's hike is relatively easy, helping you acclimate. You’ll reach Upis in the afternoon, where you can soak in natural hot springs under starry skies, with Ausangate towering in the background.

Day 2: Upis – Arapa Pass – Pucacocha

Hiking Distance: 12–14 km

Elevation Gain: ~500m

Camp: Pucacocha Lake (4,600m)

The second day brings your first major pass: Arapa Pass (4,850m). The ascent is steady, offering panoramic views of the surrounding peaks and valleys. After the pass, you’ll descend into the stunning Pucacocha valley, with its vivid blue and green lakes reflecting the glaciers above.

Day 3: Pucacocha – Ausangate Pass – Rainbow Mountain – Ananta

Hiking Distance: 14–16 km

Highest Elevation: ~5,100m

Camp: Ananta or closer to Rainbow Mountain (depending on itinerary)

This is the most challenging and rewarding day. You’ll cross the Ausangate Pass (5,100m) and see some of the most stunning glacier-carved landscapes in Peru. In the afternoon, you’ll visit Rainbow Mountain, one of the trek’s most iconic sights. Prepare for steep climbs and thinner air — but also unparalleled scenery.

Day 4: Ananta – Warmisaya Pass – Cusco

Hiking Distance: 6–8 km

Drive Back: ~4 hours to Cusco

On your final day, you’ll make a short climb to Warmisaya Pass (5,000m), where you’ll get one last panoramic view of the mountains. Then it’s a downhill trek to your pickup point, followed by the return drive to Cusco.

What to Pack

At high altitudes, weather conditions can shift quickly. Here’s a quick packing checklist for the 4-day Ausangate Trek:

Base layers: Moisture-wicking and thermal

Insulating layer: Down jacket or fleece

Waterproof shell: Rain jacket & pants

Hiking boots: Broken-in and waterproof

Sleeping bag: Rated to at least -10°C (14°F)

Trekking poles: Highly recommended

Hat, gloves, and sunglasses

Sunscreen and lip balm with SPF

Water purification method (or tablets)

Daypack + large backpack (or use a horse/mule porter)

Tips for Success

Acclimatize in Cusco for at least 2–3 days before starting the trek. Altitude sickness is real — and potentially dangerous.

Stay hydrated and eat well. Your body needs energy at high altitudes.

Go with a reputable guide or tour operator, especially if it’s your first time trekking in Peru. They’ll handle logistics, gear, and help you stay safe.

Train beforehand. Cardio and leg strength are key. Try hiking at elevation if possible.

Final Thoughts

The 4-day Ausangate Trek is not for the faint of heart — but it’s one of the most spectacular adventures Peru has to offer. Far from the crowds of the Inca Trail or Rainbow Mountain day tours, this trail immerses you in raw nature, ancient Andean culture, and landscapes that will leave you speechless.
