Trekking in Peru is one of the most unforgettable experiences for nature lovers, adventurers, and history enthusiasts worldwide. The unique blend of snow-capped Andean peaks, cloud forests, living Quechua traditions, and the thrill of reaching Machu Picchu on foot makes Cusco the world capital of alpine trekking.
Among the many ways to reach the lost citadel, two routes stand out above all others: the iconic Classic Inca Trail and its world-famous alternative, the Salkantay Trek. While both lead to the same wonder of the world, their landscapes, difficulty, permits, and experiences differ drastically.
In this detailed comparison, Peru by Locals helps you decide which route is right for your Peruvian adventure!

What is the Salkantay Trek?
The Salkantay Trek is an epic 5-day mountain route that skirts the southern slopes of Mount Salkantay (6,271 m / 20,574 ft), one of the most sacred protector deities (Apus) in Andean cosmology.
Selected by National Geographic Adventure magazine as one of the 25 best treks in the world, this route takes hikers across an immense range of ecological zones—from freezing glacial lakes like the turquoise Humantay Lake to steamy banana and coffee plantations in the Santa Teresa Valley.
Crucially, the Salkantay Trek is not restricted by government permits, making it the top choice for travelers who decide to visit Peru without booking 6 months in advance.
Jose Condor's Advice: If you are planning with less than 4 months of anticipation or you want higher glacial drama and glamping in glass Sky Domes under starry Andean skies, Salkantay is unrivaled. If walking on authentic 500-year-old Inca stone roads and entering Machu Picchu through the Sun Gate (Inti Punku) is your lifelong dream, secure your Inca Trail permits 5 to 7 months in advance!
What is the Classic Inca Trail?
The Inca Trail to Machu Picchu is universally recognized as one of the world's greatest hiking pilgrimages. Part of the legendary Qhapaq Ñan road system that united the Inca Empire, this 42-kilometer trail features original hand-laid stone paths and stone staircases constructed over 500 years ago.
Along the way, hikers explore exclusive archaeological complexes—such as Patallacta, Runkurakay, Sayacmarca, Phuyupatamarca, and Wiñay Wayna—that can only be accessed on foot by registered Inca Trail hikers. The climax occurs on the final morning, when hikers walk through Inti Punku (The Sun Gate) to catch their first morning view of Machu Picchu.

Difficulty: Distance, Duration & Elevation Gain
Duration and Distance of the Salkantay Trek
The classic Salkantay itinerary spans 5 Days / 4 Nights, covering approximately 74 kilometers (46 miles). Hikers walk between 6 to 9 hours per day across diverse terrain. The ascents are long and steady, while the descents into the valley follow wider dirt trails.
Duration and Distance of the Inca Trail
The Classic Inca Trail covers 42 kilometers (26 miles) over 4 Days / 3 Nights. Although significantly shorter in total mileage than Salkantay, it is equally or even more physically punishing on the knees and leg muscles due to thousands of uneven stone steps.
On Day 2 alone, hikers must ascend over 1,200 vertical meters up steep stone stairs to conquer Dead Woman’s Pass (Warmiwañusqa), followed by a steep 1,000-meter stone descent to the Pacaymayo valley.
Altitude & Highest Mountain Passes
Altitude is the single greatest challenge on any Andean hike. Here is how the two routes compare:
- Salkantay Trek Highest Point: The Salkantay Pass reaches 4,600 meters (15,091 ft). Hiking at this elevation requires robust acclimatization. You will feel the thin air acutely as you navigate the rocky switchbacks beside the glacier.
- Inca Trail Highest Point: Warmiwañusqa (Dead Woman's Pass) reaches 4,215 meters (13,828 ft), followed by a second pass at 3,950 meters (Runkurakay). While lower than Salkantay by 385 meters, the steepness of the stairs makes this pass grueling.
Acclimatization Golden Rule: Never start Salkantay or the Inca Trail on your first 48 hours in Cusco! Arrive 2 to 3 days prior. Sip Muña (Andean mountain mint) or coca tea, maintain high hydration (3+ liters of water daily), avoid alcohol, and take easy walks around Cusco or the Sacred Valley to give your red blood cells time to adjust naturally.
To avoid acute mountain sickness (AMS), we strongly recommend spending a minimum of 2 to 3 days resting and exploring easier tours in Cusco, such as the Cusco City Tour or the Sacred Valley Tour. Check out our dedicated guide on how to prevent altitude sickness.
Scenery, Ecosystems & Archaeology
Salkantay Trek Scenery
Salkantay is all about majestic raw nature. You experience alpine moraines, massive glaciers, rushing waterfalls, crystal lakes, and dense cloud jungle filled with exotic flora and fruit plantations. However, there is very little Inca archaeology along the first 3 days of the trek until you reach Llactapata on Day 4.
In ancient Quechua belief, Mount Salkantay ("The Wild Protector") represents male fertility and meteorological authority over the valleys below. When our native Quechua guides reach the pass, we still practice the K'intu ceremony—holding three sacred coca leaves in prayer to thank Mother Earth (Pachamama) for protection and mountain blessing.
Inca Trail Scenery & Archaeology
The Inca Trail offers an unparalleled fusion of nature and history. You are literally hiking inside a protected historic sanctuary along preserved 15th-century imperial roads. You pass through cloud forests enveloped in hanging mosses and blooming wild orchids, exploring several massive archaeological citadels every single day.
Weather Conditions & Microclimates
Because both treks traverse different elevations, you will experience extreme temperature swings:
- Salkantay: High mountain campsites (Soraypampa) drop below freezing (0°C to -5°C / 23°F) at night. By Day 3 in Chaullay and Santa Teresa, daytime temperatures reach 25°C (77°F) with high humidity.
- Inca Trail: Nighttime temperatures at Pacaymayo reach 0°C to 4°C. Near Wiñay Wayna and Machu Picchu, weather is mild and tropical (18°C to 24°C).
The dry season (May to September) brings clear sunny days and cold nights. Read our full analysis of climate and weather in Cusco and Machu Picchu.
Accommodation: Campsites, Domes & Hotels
Salkantay Trek: Salkantay offers greater accommodation flexibility. On private Peru by Locals tours, you can stay in scenic glass Sky Domes at Soraypampa with views of the stars, comfortable luxury campsites, and on the 4th night, a private hotel room with hot showers in Aguas Calientes town.
Inca Trail: Under government conservation rules, all hikers must sleep in designated wilderness campsites within the national park for all 3 nights. While facilities are rustic, Peru by Locals provides spacious 4-season Eureka tents, thick sleeping pads, dining tents with warm meals, and our exclusive private chemical toilet tents.
Permits, Availability & Pricing
Inca Trail Permits: Government regulations strictly limit Inca Trail access to 500 people per day (which includes approximately 300 porters and guides, leaving only 200 tourist permits). For peak months (May through August), permits typically sell out 5 to 7 months in advance. The Inca Trail costs between $900 and $1,050 USD per person due to non-refundable government permit fees and porter wages.
Salkantay Availability: Salkantay does not have a trail permit cap. You only need entrance tickets to Machu Picchu and train tickets. Trips can be booked with 3 to 6 weeks’ notice, and prices range from $700 to $850 USD per person.

Frequently Asked Questions
Yes! Salkantay is the #1 recommended alternative when Inca Trail permits sell out. It offers higher alpine passes, stunning views of Mount Salkantay (6,271 m) and Humantay Lake, and descends into the subtropical cloud forest before visiting Machu Picchu.
No. Only Inca Trail hikers enter Machu Picchu through the Sun Gate on foot. On Salkantay, you hike to Aguas Calientes, spend the night in a comfortable hotel, and enter Machu Picchu the next morning through the main entrance.
The Salkantay Trek reaches a higher maximum elevation of 4,630 meters (15,190 ft) at the Salkantay Pass, compared to the Inca Trail's highest point at Dead Woman's Pass (4,215 meters / 13,828 ft).
Classic Inca Trail permits must be booked 4 to 7 months in advance for peak season (May - August). Salkantay Trek can generally be booked 3 to 6 weeks in advance, though earlier booking guarantees preferred train and Machu Picchu circuit times.
