Humantay Lake Hike: Difficulty, Altitude & What to Bring

Tucked high in the Peruvian Andes, Humantay Lake is one of the most stunning alpine lakes in South America — a turquoise gem set beneath the towering, snowcapped Humantay Mountain. It’s become a popular day trip from Cusco, and for good reason. But how hard is the hike, and what should you pack? Here’s your complete guide.

Why Visit Humantay Lake

• Glacial Beauty: The vivid blue-green lake is fed by glacial melt, creating a surreal contrast with the surrounding white peaks.
• Spiritual Significance: This area has long been sacred to the Quechua people, and many travelers feel a peaceful, grounding energy here.
• Photo-Worthy Views: It’s one of the most photogenic spots in Peru, with mirror-like reflections of the Humantay and Salkantay peaks.​

Hike Difficulty

• Trek Distance: Approximately 7 kilometers (4.3 miles) round trip
• Duration: 1.5 to 2 hours uphill, about 1 hour downhill
• Altitude: The trail starts around 3,900 meters (12,800 feet) and climbs to about 4,200 meters (13,800 feet)​

The path is steep, especially toward the top, and the high altitude adds a level of difficulty. Even
physically fit travelers may find themselves out of breath.

Tip: Horses are available to rent on-site if the hike becomes too strenuous.

Altitude Tips

• Spend 2–3 days acclimating in Cusco or the Sacred Valley before attempting the hike​
• Drink plenty of water and coca tea
• Avoid alcohol and heavy meals the day before
• Walk slowly, take breaks, and listen to your body​

What to Bring

• Warm layers (mornings are cold, but you’ll warm up quickly while hiking)
• Rain jacket (mountain weather is unpredictable)
• Hiking boots or trail shoes with good grip
• Reusable water bottle (single-use plastics are banned)
• Sunscreen, sunglasses, and a hat
• Snacks or a packed lunch
• Cash (for bathrooms, horse rental, or tipping your guide)​
