Peru.

Peru is South America's most diverse country by altitude and ecosystem. A single 2-week trip can take you from sea-level Lima at 12°C and gray garúa skies, up to Cusco at 3,399m (higher than most ski resorts), down through the Sacred Valley at 2,800m, into the cloud forest at Machu Picchu (2,430m), to the floating reed islands of Lake Titicaca at 3,812m, and into the Amazon basin at 200m. No other South American country squeezes this much vertical and ecological range into a manageable circuit.

The icons earn the hype. Machu Picchu is the most-photographed ruin in the Americas and remains genuinely breathtaking despite the crowds, the citadel emerging from cloud forest at sunrise still does something to people. The Sacred Valley (Pisac, Ollantaytambo, Chinchero, Maras, Moray) is arguably more rewarding than Cusco itself, with terraced ruins, working markets, and Inca-era salt pans still in production. The Inca Trail is one of the world's iconic multi-day treks, and the alternatives (Salkantay, Lares, Choquequirao) offer equal scenery with fewer permit headaches.

The Amazon is non-trivial. Peru holds 13% of the Amazon basin, second only to Brazil. The two main entry points are Iquitos (deepest, only reachable by plane or boat, gateway to Pacaya-Samiria) and Puerto Maldonado (1-hour flight from Cusco, gateway to Tambopata and the easier-to-reach Madre de Dios region). Manu National Park is the wildest of the three but logistically hardest. Lodge stays run 3–5 nights, full board, $250–450/night.

Peruvian food is a destination unto itself. Lima has been called the culinary capital of South America for the better part of a decade, Central, Maido, and Astrid y Gastón rotate through the World's 50 Best lists, and a tier of mid-priced cevicherías (Punto Azul, Pescados Capitales, La Mar) deliver world-class ceviche for $10–25 a plate. Pisco sour, lomo saltado, ají de gallina, anticuchos, causa, rocoto relleno, Peru's culinary range tracks its geographic range.

Altitude is the single biggest planning factor. Cusco at 3,399m hits hard if you fly in directly from sea level, most travelers feel headache, nausea, fatigue, and insomnia for the first 24–48 hours. The traditional fix is mate de coca (coca-leaf tea), aggressive hydration, and 2–3 days of acclimatization before any serious trekking or Machu Picchu. Counterintuitively, Machu Picchu (2,430m) is lower than Cusco, most trekking routes climb from Cusco and then descend into the cloud forest. The Sacred Valley at 2,800m is a smarter acclimatization base than Cusco itself for altitude-sensitive travelers.

Peru's three zones don't share a calendar. Pick your priority zone, build the trip around it, and accept that the others won't be at their peak.

ANDES (Cusco, Sacred Valley, Machu Picchu, Lake Titicaca, Rainbow Mountain, Colca Canyon). The dry season runs May through October, with peak conditions June–August: clear skies, daytime 18–22°C in Cusco, near-freezing nights at higher altitudes, almost no rain. This is when the Inca Trail, Salkantay, Lares, and Rainbow Mountain hikes are at their best, and when 75% of foreign tourism happens. Permits and lodges book 3–6 months ahead. Wet season (November–April) brings daily afternoon downpours, typically clear mornings, building cloud, rain from 2 p.m. onward. The mountains turn brilliantly green, crowds drop sharply, and prices ease 20–35%. The trade-offs: muddy trails, occasional landslides closing the Cusco–Aguas Calientes train line, and the Inca Trail closed entirely in February for maintenance. Travelers who plan for mornings-only sightseeing in the wet season often report it as their favorite Peru visit.

AMAZON (Iquitos, Puerto Maldonado, Manu). The Amazon runs on its own water-driven rhythm. High-water season (December–May) floods the lower forest, canoe trips reach areas inaccessible by foot, fish are easier to spot, and wildlife concentrates on remaining higher ground (often more visible, not less). Low-water season (June–November) exposes river beaches, opens hiking trails, and makes mammals like tapir and capybara easier to spot at riverbanks. Both seasons have merit. The traditional 'best Amazon time' wisdom favors May–October (dry, fewer mosquitoes), but serious wildlife photographers often prefer December–April for the canoe access. Mosquitoes and rain occur year-round in the Amazon, there is no truly dry month.

COAST (Lima, Paracas, Ica, Nazca, Northern beaches). The coast is one of the world's driest regions, Nazca and Ica receive less rain than the Sahara. The twist is Lima's garúa, a thick gray sea-mist that smothers the city from May through October (overcast, 14–19°C, no actual rain but persistent damp). December through April flips Lima into bright summer at 24–29°C, perfect for Miraflores boardwalks and the southern beach towns of Punta Hermosa and Asia. Paracas (sand dunes, sea-lion-packed Ballestas Islands), Ica (Huacachina oasis sandboarding), and the Nazca Lines fly best year-round but are most pleasant in late autumn and early spring (Apr–May, Sep–Oct) when the heat is moderate. The northern beaches (Máncora, Punta Sal) stay tropical year-round (24–28°C water) and are best December–April.

The implication for trip design. A January–March trip favors coast and Amazon high-water while accepting wet-season Andes. A June–August trip favors Andes peak while accepting garúa gloom in Lima and dustier (but more accessible) Amazon. April–May and September–October are the best multi-zone compromise windows, the Andes are still dry, Lima is transitioning out of or into garúa, and the Amazon is in shoulder conditions. For most first-time travelers prioritizing Machu Picchu, target May or September.

Machu Picchu was redesigned in 2024 with a new timed-circuit ticketing system and 2026 brings further changes, including increased visitor caps for guided tours and new circuits along the Huayna Picchu route. The current capacity is approximately 4,500 visitors per day in high season, distributed across morning (6 a.m.–12 p.m.) and afternoon (12 p.m.–5:30 p.m.) slots and four numbered circuits.

The four circuits in brief:

• Circuit 1: high-route panoramic, best classic 'postcard view' from the upper terraces, lighter on time inside the citadel.
• Circuit 2: the most comprehensive, the standard route hitting the Sun Gate viewpoint, the Temple of the Sun, the Three Windows, and most major structures.
• Circuit 3: lower citadel, closer to the agricultural and residential zones, less of the postcard view.
• Circuit 4: the Royal Inca route, combinable with Huayna Picchu or Machu Picchu Mountain hikes.

Most first-time visitors should book Circuit 2 morning slot. Add Huayna Picchu (the iconic peak behind the citadel, 1.5–2hr round-trip steep climb, 400 permits per day, books 2–3 months ahead) or Machu Picchu Mountain (longer, less crowded, similar elevation gain) for a full day. Tickets release on the official platform (tuboleto.cultura.pe) in waves throughout the year, book 1–3 months ahead for high-season May–September, 2–3 weeks is often enough off-peak.

The Inca Trail (4-day Classic Trek). The original route over the Andes into Machu Picchu, 45 km in 4 days, climbing through three high passes (the highest, Dead Woman's Pass, hits 4,215m). 500 permits per day total (covering hikers, guides, and porters, meaning ~200 hiker spots), books out 5–8 months ahead for June–August, 2–4 months ahead for May and September. The trail is closed for the entire month of February every year for maintenance, 2026 reopening is March 1. Costs run $700–900 budget, $1,200–1,800 mid-range, $2,500+ luxury (4-day inclusive of porters, food, gear, guides, train back, and Machu Picchu entry). The 2-day 'Short Inca Trail' is also available, much easier, cheaper ($560–640), and a good fallback if Classic permits sell out.

Alternatives if Inca Trail is sold out (or in February):

• Salkantay Trek: 5-day route around the snow-capped Salkantay peak (6,271m), often considered more scenic than the Inca Trail itself. No permit cap, bookable 1–4 weeks ahead. Higher altitude (max pass 4,630m). Runs year-round but February's snow at the Salkantay pass adds risk. $400–700 budget tier, $700–1,200 mid-range.
• Lares Trek: 4-day route through traditional Quechua villages, less touristed, more cultural focus, lower altitude (max pass 4,400m). $400–650.
• Choquequirao: the 'sister city' of Machu Picchu, 2-day brutal in-and-out hike (1,500m descent then 1,500m climb each way), virtually empty. For experienced trekkers only. Plans exist for a cable car that would transform access, currently in development.
• Inca Jungle Trek: 4-day mountain-biking + rafting + zipline + hiking package. The 'fun' option. $250–450.

All Machu Picchu trips ultimately funnel through Aguas Calientes (also called Machu Picchu Pueblo), the small town at the base of the citadel. Most independent travelers take the PeruRail or Inca Rail train from Cusco's Poroy or Ollantaytambo station, $80–200 round-trip, depending on service class (Expedition, Vistadome, 360°, Hiram Bingham luxury). From Aguas Calientes, the bus to Machu Picchu's entrance costs $25 round-trip and runs every 10 minutes from 5:30 a.m. Build a buffer day: trains do get cancelled in the wet season, and missing your timed Machu Picchu slot is non-refundable.

Altitude planning specific to Machu Picchu. Cusco at 3,399m and the Sacred Valley at 2,800m both sit higher than Machu Picchu (2,430m). Counterintuitively, Machu Picchu is your lowest stop in the Andean leg. Do not fly Lima → Cusco → Machu Picchu in 24 hours. The standard sequence: arrive Cusco, two nights in the Sacred Valley first (lower altitude, gentler acclimatization), then Machu Picchu, then return to Cusco for the higher-altitude exploration. Symptoms of soroche (altitude sickness) include headache, nausea, fatigue, insomnia, and shortness of breath, treat with rest, water, mate de coca, and (if persistent) descent. Diamox (acetazolamide) is a prophylactic prescription option, talk to your doctor 2–3 weeks before departure. Avoid alcohol for the first 48 hours and keep heavy meals light.

Visa. Most Western passports get 90 days visa-free on arrival in Peru, US, UK, Canada, Australia, EU, New Zealand, Japan. Stamp on entry. Passport must be valid for 6 months beyond entry. The 90 days can be extended in-country with paperwork through Migraciones, but most travelers don't need it.

Domestic flights. LATAM Peru, Sky Airline, JetSmart, and Star Perú run the main internal routes. Lima–Cusco is the workhorse at $50–150 each way, 1.5 hours, with frequent daily departures. Lima–Iquitos and Lima–Puerto Maldonado for Amazon connections; Lima–Arequipa for the Colca Canyon; Lima–Trujillo for the northern coast. Book 4–8 weeks ahead for Lima–Cusco peak season pricing. Lima's Jorge Chávez airport handles all international and most domestic connections (a long-delayed second terminal opened 2025, connection logistics are now smoother).

Long-distance buses. Peru has one of South America's best inter-city bus networks. Cruz del Sur is the gold standard, fully reclining 'cama' or 'suite' lie-flat seats for overnight routes, GPS tracking, snacks, onboard movies. Movil Tours, Oltursa, and Civa are the mid-tier alternatives. Lima–Cusco is 22–24 hours overnight ($60–110 in lie-flat suite); Lima–Arequipa is 14–16 hours; Lima–Trujillo is 8–10 hours. Buses are dramatically cheaper than flights and the overnight routes save a hotel night. Petty theft does happen on buses, keep daypacks on your lap, valuables under your shirt, never in overhead compartments.

Trains to Machu Picchu. PeruRail and Inca Rail are the two operators. Vistadome (panoramic windows) is the standard tourist class. Expedition is the basic option. Hiram Bingham is the luxury Belmond service ($750+) with multi-course meals and live music. The standard route is Ollantaytambo → Aguas Calientes (1.5 hours), most travelers take a colectivo or taxi from Cusco to Ollantaytambo, then board there. Direct Poroy → Aguas Calientes routes from Cusco are limited and seasonal.

Cusco taxis and ridesharing. InDriver and Uber work in Cusco and Lima, dramatically safer and cheaper than street taxis. Off-the-street taxi hailing in Lima is the historical scene of 'express kidnapping' scams (driver routes through ATMs, cleaning out the victim's account), use ridesharing apps universally. In Cusco, taxis from Plaza de Armas to Sacsayhuamán or San Pedro are 10–20 soles ($3–6).

Currency. Peruvian Sol (PEN) is the local currency, roughly 3.7 PEN = $1 USD at recent rates. USD is widely accepted at tourist sites (Cusco shops, Machu Picchu, Sacred Valley markets) but at slightly worse rates than paying in soles. ATMs are everywhere in cities, BCP (Banco de Crédito) has the best ATM coverage and supports international cards reliably; Globalnet ATMs charge high foreign fees, avoid. Cards work at hotels, mid- and upper-tier restaurants, and tourist sites; markets, buses, and small cevicherías are cash-only.

Tipping. 10% in restaurants if service charge isn't already included (look for servicio on the bill). $10–15 per day per porter on the Inca Trail is standard, this is socially mandatory, and the porter labor structure is historically exploitative; tipping properly is a small but meaningful corrective. Tour guides: $10–15/day for group tours, $20–30/day for private. Hotel housekeeping: 5–10 soles/day.

Language. Spanish is the dominant language; Quechua is widely spoken in the Andes (Cusco, Sacred Valley, Puno regions); Aymara around Lake Titicaca. Tourist English exists in Cusco, Lima, and major sites but fades quickly off the gringo trail. Five Spanish phrases get you most of the way: buenos días/tardes/noches, gracias, por favor, cuánto cuesta? (how much?), no, gracias. Quechua words like Allillanchu? (how are you?) and Sulpayki (thank you) are deeply appreciated in Andean villages.

Scams to know.

• Express kidnapping in Lima (historical, much reduced but real), never hail a street taxi; use Uber/InDriver/Cabify exclusively.
• Counterfeit soles, examine 50 and 100 sol notes for the watermark and security strip; ATMs from major banks are safest.
• 'Tour guide' redirects in Cusco, strangers near Plaza de Armas offering 'free tours' that funnel you into shopping stops.
• Train station overcharging at Aguas Calientes for last-minute tickets, book Machu Picchu trains in advance online.
• Money exchange short-changing, count cash before stepping away from the window.

Health.

• Tap water is NOT drinkable, even in Lima. Bottled, filtered, or boiled only. Avoid ice in non-tourist establishments. This is the single most common source of traveler stomach issues.
• Vaccinations. Yellow fever is recommended for jungle entry, some Amazon lodges in the lowlands require a certificate. Hepatitis A, B, typhoid, and tetanus are standard recommendations. Malaria prophylaxis is low-priority on the standard tourist circuit but worth discussing with a travel doctor for deep Amazon trips. Zika and dengue are present in lowland and jungle areas, long sleeves and DEET in those regions.
• Stomach issues are common. Avoid raw vegetables and salads outside high-end restaurants; peel your own fruit; ask for drinks 'sin hielo' (no ice) outside tourist hotels.
• Coca leaves and mate de coca are legal and traditional throughout the Andes, chewing the leaves or drinking the tea genuinely helps with altitude. Coca will trigger a positive on US drug tests, don't take leaves home.

Etiquette. Bargaining is expected at markets, start at 50–60% of the asking price and meet in the middle. Always ask before photographing people, especially Andean indigenous people in traditional dress in Cusco's Plaza de Armas, they are working and typically request 2–5 soles per photo. Modest dress is appreciated for churches; never climb on archaeological ruins or stones (this is a serious offense and visitors have been arrested).

Peru is one of South America's best-value destinations, significantly cheaper than Chile or Argentina, comparable to Bolivia or Ecuador, dramatically below Brazil's coastal cities. A strong mid-range Peru trip can be done for 40–55% of an equivalent New Zealand or Costa Rica budget.

Daily budget guidelines for 2026 (excluding international flights):

• Backpacker / hostels and street food: $40–60/day per person. Hostel dorm $10–18, menú del día lunches $4–8, basic colectivo and combi transport, walking tours, group treks at the budget tier.
• Mid-range / nice hotels and good restaurants: $80–150/day per person. Boutique hotel rooms $60–120, restaurant meals $12–25, mix of domestic flights and premium buses, mid-tier guided tours.
• Comfort / 4–5 star and luxury: $250–500+/day per person. Top hotels (Belmond, JW Marriott Cusco, Tambo del Inka), private drivers, Hiram Bingham train, high-end Amazon lodges.

The Machu Picchu day cost, what it actually adds up to.

• Machu Picchu entrance: ~152 soles ($40 USD) for foreigners on a standard circuit.
• Round-trip train (Ollantaytambo–Aguas Calientes, Vistadome class): $130–180.
• Round-trip bus (Aguas Calientes to citadel): $25.
• Optional guide: $20–35 for a 2-hour group tour at the entrance, $60–100 for a private guide booked ahead.
• One night in Aguas Calientes: $40–150 depending on tier.
• All-in for a single Machu Picchu visit (excluding Cusco accommodation): $250–400 per person.

Inca Trail tier comparison (4-day Classic, all-inclusive):

• Budget tier ($700–900): shared porters carrying group gear, basic meals, group of 12–16 hikers, simple double-occupancy tents. Reputable operators in this tier: SAM Travel, Llama Path, Alpaca Expeditions (entry-level packages).
• Mid-range ($1,200–1,800): better porters-to-hikers ratio, upgraded sleeping pads, hot meals with 3-course dinners, smaller groups (8–10), better gear. Alpaca Expeditions premium, Llama Path premium, Apus Peru.
• Luxury ($2,500+): Mountain Lodges of Peru's lodge-to-lodge variant (sleep in fixed lodges, not tents), Belmond's package with Hiram Bingham return train, private guides. The high-end is closer to a mid-range African safari pricing-wise.

Where to save in Peru.

• Eat menús del día. Lunch sets at locals' restaurants run 8–18 soles ($2–5) for a starter, main, and drink. They're filling, fresh, and authentic.
• Take overnight Cruz del Sur buses for one or two long routes, saves a hotel night and runs $60–110 in lie-flat 'suite' class.
• Book Machu Picchu trains and tickets independently online, agency markup is often 30–50%.
• Skip the Hiram Bingham unless luxury is the point, Vistadome offers the same panoramic windows for 25% of the price.
• Use ridesharing apps (InDriver, Uber, Cabify) instead of street taxis in cities.
• Travel May, September, or October, shoulder dry-season months, for 15–25% off peak Cusco hotel rates with near-peak weather.

Where the costs hide.

• Domestic flight churn: Lima–Cusco prices double in peak weekends; book mid-week.
• Aguas Calientes premium: meals, snacks, water, and souvenirs are 2–3× Cusco prices.
• Tipping the Inca Trail crew ($75–150 total per hiker on a 4-day) is real and not optional.
• Sacred Valley to Cusco transport: hotels often inflate the airport-shuttle price by 3–5×; pre-book taxis through hostels or use InDriver.
