Hiking in Peru: Inca Trail, Salkantay & Andes Treks
Peru's walking is crowned by the Inca Trail to Machu Picchu, with the Salkantay and the Cordillera Blanca offering superb alternatives. This guide covers the classic treks and the permit reality.
Hiking involves real physical risk. Route conditions, weather, and your fitness all affect safety — check local trail conditions and forecasts before you go, carry navigation, water, and layers, and never hike beyond your ability. Times and difficulty descriptions here are general guidance, not a guarantee; consider a local guide for remote or high-altitude routes.
Peru holds South America's most famous walk — the Inca Trail to Machu Picchu — and a supporting cast that rivals it: the Salkantay's high-altitude drama, the Cordillera Blanca's Santa Cruz trek beneath 6,000-metre peaks, and the Colca Canyon's condor-patrolled depths. The Andes here are higher, drier, and more archaeological than anywhere else on the continent. The planning essentials are the Inca Trail permit system (booked out months ahead), altitude acclimatisation in Cusco, and the May-September dry season. Walk Peru in the dry months and the Andes deliver the continent's definitive trekking. The porter welfare question matters: choose operators with published fair-treatment policies, because the trek's human story is as important as the stones.
The Inca Trail: the classic, honestly assessed
The Inca Trail — 4 days along Inca stone paths over the Dead Woman's Pass to the Sun Gate and Machu Picchu at dawn — is justifiably famous and genuinely wonderful: the archaeology en route (Wiñay Wayna, Sayacmarca) is superb, the porters and cooks are the trek's heart, and the dawn arrival is unforgettable. The honest caveats: permits are capped at 500 people per day (including staff) and sell out 4-6 months ahead for the dry season — book through a licensed operator the moment you know your dates. The trail is busy, the fixed itinerary allows no flexibility, and February closes it for maintenance. It's a bucket-list walk that earns the hype, provided you book early and arrive acclimatised. The Winay Wayna ruins — the trail's largest archaeological site — deserve an unhurried hour: most groups rush past, but the terraces reward slow looking.
Salkantay: the great alternative
The Salkantay trek — 5 days from the Sacred Valley over the 4,630m Salkantay Pass to Aguas Calientes and Machu Picchu — is the Inca Trail's great rival and many walkers' preference: higher, wilder, and more varied, from glaciated peaks through cloud forest to coffee country. No permit cap means flexible booking; the infrastructure (glass-roofed camps, hot showers on the premium versions) is superb. The Salkantay Pass day is the crux — long, high, and cold — but the descent into the cloud forest is pure magic. For walkers who missed the Inca Trail permits or prefer bigger mountains, Salkantay is arguably the better trek. The standard advice: acclimatise in Cusco first, then walk. The Salkantay's glass-roofed camps let you watch the stars from your bed — a small luxury that makes the high-altitude nights magical.
Cordillera Blanca: the Santa Cruz trek
The Cordillera Blanca — the world's highest tropical mountain range, with 6,000-metre peaks above turquoise lakes — holds Peru's finest pure mountain trekking. The Santa Cruz trek (4 days, Huaraz-based) crosses the Punta Union pass beneath Alpamayo (once voted the world's most beautiful mountain) with camps beside impossibly blue lakes. The Huayhuash Circuit (8-10 days) is the expedition-grade classic, circling one of the Andes' great massifs. Huaraz is the trekking capital: operators, gear shops, and acclimatisation walks (Laguna 69 is the perfect shakedown). Altitude is serious — the treks sleep above 4,000m — and the dry season (May-September) is non-negotiable. This is Andean trekking at its most spectacular. The Laguna 69 day hike from Huaraz is the perfect acclimatisation test: if the altitude feels manageable there, the Santa Cruz will too.
Colca Canyon and the southern Andes
The Colca Canyon — one of the world's deepest, and home to the Andean condors soaring at Cruz del Cóndor — offers superb 2-3 day treks descending to the Sangalle oasis at the canyon floor. The classic route descends from Cabanaconde, overnights at the oasis's pools, and climbs out the next morning — a short, sharp, unforgettable trek. Arequipa's surrounding volcanoes (Misti, Chachani) provide excellent acclimatisation climbs. The southern Andes see fewer international trekkers than Cusco, which means lower prices and quieter trails. The dry season applies; the canyon's heat is the main challenge on the climb out. Condor sightings are best in the morning thermals — start the mirador visit early.
Cusco acclimatisation: doing it right
Altitude is the defining factor of Peruvian trekking, and Cusco (3,400m) is where you handle it. The protocol: arrive 2-3 days before any trek, spend the first day resting, take progressively higher day walks (Sacsayhuamán, the Sacred Valley, then a higher excursion), hydrate constantly, limit alcohol, and consider the coca tea the locals swear by. The Inca Trail's Dead Woman's Pass (4,215m) and Salkantay's pass (4,630m) punish the unacclimatised — most trek failures are altitude failures, not fitness failures. An elevation finder on your chosen trek shows exactly where the high sleeps fall. Diamox is a personal medical decision — discuss it with your doctor before travelling, not with your guide on day one.
When to go: the Andean dry season
The Peruvian Andes walk in the dry season, roughly May to September: clear skies, firm trails, and the famous mountain views. June-August is the peak — the Inca Trail permits vanish first, and Cusco bustles. The shoulder months (April-May, September-October) offer the sweet spot: decent weather, fewer crowds, easier bookings. The wet season (November-March) brings afternoon deluges, muddy trails, and clouded-out views; the Inca Trail closes entirely in February. Note the Inti Raymi festival in late June: Cusco's biggest celebration fills the city — magical if you plan for it, chaotic if you don't. For the classic Inca Trail or Salkantay, May and September hit the sweet spot between weather and crowds. The Qoyllur Rit'i festival (May/June) brings thousands of pilgrims to the high Andes — a cultural spectacle for trekkers already acclimatised in Cusco.
Fitness, pacing, and the permit game
Peruvian treks demand altitude fitness more than technical skill: train with loaded hill walks and stair sessions, arrive acclimatised, and pace conservatively — the Andes punish the rushed. The standard time estimate (about an hour per 5 km plus 30 minutes per 300 m of ascent) needs an altitude multiplier above 3,500m; a hiking time calculator gives the baseline. The permit game is the other discipline: Inca Trail permits 4-6 months ahead through licensed operators only, Salkantay flexible, Santa Cruz arranged in Huaraz. Use only licensed operators — the porter welfare standards matter, and the reputable companies treat their crews properly. The guide to hiking distance and time estimation covers the pacing method in full.
Frequently asked questions
How far ahead should I book the Inca Trail?
4-6 months for the May-September dry season — the 500 daily permits (including staff) sell out fast. Book through a licensed operator only; the trail closes every February for maintenance.
Is Salkantay better than the Inca Trail?
Different: Salkantay is higher, wilder, and more varied with no permit cap; the Inca Trail has the archaeology and the Sun Gate arrival. Many experienced trekkers prefer Salkantay; first-timers love the Inca Trail's story.
How do I acclimatise in Cusco?
Arrive 2-3 days before trekking, rest day one, take progressively higher day walks, hydrate constantly, and limit alcohol. Most trek failures are altitude failures — respect the process.
When is the best time to trek in Peru?
May-September (dry season); June-August is peak. April-May and September-October offer the best balance of weather and crowds. Avoid the November-March rains.
How difficult is the Santa Cruz trek?
Moderate for acclimatised walkers: 4 days, high camps above 4,000m, and the Punta Union pass. The altitude is the challenge, not the terrain. Huaraz operators run it throughout the dry season.
Can you do the Colca Canyon independently?
The classic 2-day Cabanaconde-Sangalle route is doable independently with a guide hired locally, but most visitors go with Arequipa operators. The climb out is the crux — start before dawn.
