What Is Humantay Lake?
Humantay Lake known locally as Laguna Humantay is a glacial lagoon formed at the base of the Humantay glacier. Its striking turquoise color comes from glacial meltwater rich in suspended minerals. Sitting in a natural bowl framed by the snowy peak of Humantay (6,270 m), the lake holds deep spiritual significance for the Andean Quechua people, who consider it a sacred site (Apu).
Unlike the classic Salkantay Trek which takes 5 days, the Humantay Lake hike can be completed in a single day from Cusco making it one of the most accessible high-altitude experiences in the region.
The Trail: Step by Step
Starting Point: Soraypampa
The hike begins at Soraypampa (3,900 m), a small highland plain with a basic camp and facilities. Most visitors arrive here by private van or tour bus from Cusco, which takes around 3.5 hours via the town of Mollepata.
The Ascent: 300m of Elevation Gain
From Soraypampa, a well-defined trail climbs steeply up the mountainside for approximately 2 km to reach the lake at 4,200 m. The path is rocky and can be slippery in wet conditions, but it is well-marked throughout.
Expect the uphill section to take 1 to 1.5 hours depending on your fitness level and how well you’ve acclimatized. The final 500 meters before the lake are the steepest — take your time and breathe slowly.
At the Lake
Once you reach the summit of the trail, the view is simply breathtaking. The turquoise waters of Humantay Lake reflect the surrounding peaks, and on clear days you can see the Humantay glacier above. Most hikers spend 30–45 minutes at the lake to rest, take photos, and participate in a small offering ceremony if guided by a local.
The Descent
The return to Soraypampa takes around 45 minutes to 1 hour. The path is the same as the ascent. Take care on loose gravel sections, especially after rain.
Trail Difficulty: Is the Humantay Lake Hike Hard?
The Humantay Lake hike is rated moderate. Here’s what to expect:
- Total distance: ~4 km round trip
- Elevation gain: ~300 m from the trailhead
- Duration: 2–3 hours total
- Terrain: Rocky, unpaved trail with steep sections
- Altitude: Maximum of 4,200 m
The main challenge is not the distance but the altitude. If you haven’t spent at least 2 days in Cusco (3,400 m) before attempting this hike, altitude sickness can significantly affect your experience.
Compared to multi-day treks like the Inca Trail or the full Salkantay Trek, this is a much shorter and more accessible challenge. However, it is not suitable for people with serious heart or respiratory conditions without medical clearance.
Altitude & Acclimatization: What You Need to Know
At 4,200 meters, altitude sickness (known as soroche in Peru) is a real concern. Here’s how to prepare:
Symptoms to Watch For
- Headache (most common symptom)
- Nausea or vomiting
- Dizziness and fatigue
- Shortness of breath beyond normal exertion
- Loss of appetite
How to Prevent Altitude Sickness
- Spend at least 2 nights in Cusco before hiking
- Stay well hydrated — drink 2–3 liters of water per day
- Avoid alcohol for 24–48 hours before the hike
- Eat light, high-carbohydrate meals
- Walk slowly and take regular breaks («poco a poco» as locals say)
- Consider taking Diamox (acetazolamide) — consult your doctor
- Try coca leaf tea, widely available in Cusco and along the trail
What to Pack for the Humantay Lake Hike

How to Get to Humantay Lake from Cusco
Option 1: Guided Day Tour (Recommended)
The easiest and most popular way to visit Humantay Lake is by joining a guided day tour from Cusco. Tours typically include round-trip transportation, a local guide, entrance fees, and a meal at Soraypampa. Our peru vacation packages include a full-day Humantay Lake excursion as an optional add-on, perfect for acclimatization before tackling longer treks.
Option 2: Private Transfer + Self-Guided
If you prefer independence, you can hire a private taxi or minibus to Soraypampa. From there, the trail is straightforward and easy to follow without a guide. However, hiring a local guide is recommended to learn about the cultural and ecological significance of the area.
Option 3: As Part of the Salkantay Trek
Many multi-day Salkantay Trek itineraries include a visit to Humantay Lake on Day 1. If you book a peru guided tours package for the Salkantay Trek, the lake visit is typically included as the first highlight of the journey.
Best Time to Visit Humantay Lake
The best time for the Humantay Lake hike is during the dry season, which runs from April to October. During these months, you’ll enjoy clear skies, stable trail conditions, and stunning views of the surrounding peaks.
| Season | Conditions |
|---|---|
| April – October | Dry season — best visibility and trail conditions |
| November – March | Rainy season — trails can be muddy and slippery |
| June – August | Peak season — busiest but most reliable weather |
| April–May / Sept–Oct | Shoulder season — fewer crowds, good conditions |
Entrance Fees & Practical Information
As of 2026, there is a community entrance fee to access the Humantay Lake trail, typically collected at a checkpoint near Soraypampa. The fee is around S/10–S/20 (approximately USD 3–6) per person and goes directly to the local community maintaining the trail.
If you book through a peru travel agency, entrance fees are typically included in your tour price. Always confirm this when booking.
