Inca Trail vs. Salkantay Trek vs. Lares Trek: Which One Is Right for You?

Ask ten travelers which trek to Machu Picchu is "the best," and you'll get ten different answers. That's because the three most popular routes - the Inca Trail, the Salkantay Trek, and the Lares Trek, aren't really competing with each other. They're built for different people. One is about walking in the literal footsteps of the Inca Empire. One is about glaciers, alpine lakes, and pushing your legs to their limit. One is about sitting down for coca tea with a Quechua family whose grandparents lived exactly the way they still do.

At Inka Ayway, this is the question we get asked more than almost any other: which trek should I actually book? Here's the honest breakdown.

The Quick Answer

• Choose the Inca Trail if you want the classic, historic route with ancient ruins along the way and the only trail that ends by walking through the Sun Gate into Machu Picchu.

• Choose the Salkantay Trek if you want the biggest physical challenge, the most dramatic mountain scenery, and don't want to worry about limited permits.

• Choose the Lares Trek if you want a quieter trail, meaningful time in traditional Andean villages, and a gentler introduction to high-altitude trekking.

Now let's get into why.

Inca Trail: The Classic Route

Length: ~42–45 km over 4 days / 3 nights Max altitude: 4,215 m (Dead Woman's Pass) Permits: Required, limited, and often sold out 4–6 months in advance Crowds: The most heavily trafficked of the three, though a daily hiker cap keeps it from ever feeling overrun

This is the trek most people picture when they imagine hiking to Machu Picchu, and for good reason. It's the only route that follows original Inca stone pathways for most of its distance, and the only one that ends by climbing through Inti Punku - the Sun Gate - for your first view of the citadel at sunrise. Along the way you'll pass genuine archaeological sites that you can only reach on foot, including Sayacmarca, Phuyupatamarca, and Wiñay Wayna, one of the most impressive Inca terrace complexes outside Machu Picchu itself.

It's a moderately difficult trek. The altitude is lower than Salkantay's, but the trail itself is demanding in a different way, long stretches of uneven stone steps, both up and down, that work your legs hard regardless of how fit you are. The trade-off for all this history and that unbeatable ending is the permit system. Peru's Ministry of Culture caps daily hikers, and permits for peak season (June–August) routinely sell out months ahead. If history and that Sun Gate moment matter most to you, this is worth planning around.

Salkantay Trek: The Big Mountain Challenge

Length: ~55–60 km over 5 days / 4 nights (shorter 4-day options exist) Max altitude: 4,600–4,650 m (Salkantay Pass)Permits: None required, you can often book with just weeks of notice Crowds: Noticeably quieter than the Inca Trail

If the Inca Trail is a walk through history, Salkantay is a walk through raw nature. The trail climbs beneath Apu Salkantay, a 6,271-meter glaciated peak considered one of the most powerful sacred mountains in Inca cosmology, then descends dramatically over several days from icy high-altitude puna, past the turquoise waters of Humantay Lake, down through cloud forest and coffee-growing valleys before reaching Aguas Calientes.

This is the toughest of the three routes. You'll reach a higher maximum altitude than on the Inca Trail, hike longer daily distances, and face one especially grueling day climbing to and descending from Salkantay Pass often 16 to 22 km in a single stretch. There are no major archaeological sites along the way (aside from the smaller Llactapata ruins), so this trek is really for people who want the physical challenge and the scenery more than the history lesson. The upside: no permit lottery. If your travel dates are flexible or last-minute, Salkantay is almost always available.

Lares Trek: The Cultural Immersion

Length: ~33 km over 3–4 days Max altitude: 4,450–4,700 m depending on the exact route (Condor Pass or Ipsaycocha Pass) Permits: None required Crowds: By far the quietest of the three you may go hours without seeing another trekking group

Often called the "Weaver's Trail," Lares is less about a destination and more about the people you meet along the way. The route winds through remote Andean villages in the Lares Valley where Quechua families still herd alpaca, farm terraced hillsides, and weave textiles using techniques passed down for centuries. It's common to be greeted by children or elders in traditional dress, and many operators build in stops to visit a local home or weaving cooperative.

Distance-wise, this is the shortest of the three treks, which leads people to assume it's the easiest and while it is generally gentler on your legs, don't underestimate it. Depending on which pass your itinerary crosses, you can reach an altitude even higher than Salkantay's, just spread across shorter days. That makes proper acclimatization in Cusco just as essential here as on the other two routes. Most Lares itineraries end with a train ride from Ollantaytambo to Aguas Calientes rather than a walk directly into Machu Picchu.

So, Which One Should You Book?

A few honest rules of thumb:

If you booked your Peru trip more than 5 months out and history is the priority, go with the Inca Trail. The Sun Gate entrance is genuinely something you can't get any other way, and the ruins along the route are worth the extra planning.

If you're short on lead time, or you missed the permit window, Salkantay is the obvious alternative not a consolation prize, but a completely different (and for many travelers, more scenic) adventure in its own right.

If you want to slow down, connect with people rather than ruins, and avoid the busiest trails entirely, Lares is very hard to beat and it's a great option for travelers who want a real trekking experience without committing to Salkantay's physical demands.

And if you genuinely can't choose, it's worth knowing that combined itineraries exist pairing a shortened Lares or Salkantay route with a day or two on the Inca Trail for travelers who want a taste of everything.

Whichever route calls to you, the one thing all three treks have in common is this: proper acclimatization in Cusco beforehand isn't optional. Give yourself at least two full days at altitude before setting out, regardless of which trail you choose.
