South America 21-Day Itinerary: Peru, Bolivia & Argentina (2026)

Overview

South America offers some of the world’s most extraordinary travel experiences — the pre-Columbian cities of Peru (Machu Picchu, Cusco, the Sacred Valley), the surreal landscapes of Bolivia (the Uyuni salt flats, the altiplano, Lake Titicaca), and the European sophistication of Buenos Aires together form one of the world’s great long-haul itineraries.

Flights: Lima or Buenos Aires have the best transatlantic connections (Iberia from Madrid, Air France from Paris, LATAM from most European cities) Best season: May–September (winter/dry season in the Andes, optimal for Machu Picchu and the salt flats) Budget: $70–120/day budget; $200–400/day mid-range; $500+/day luxury

Days 1–2: Lima, Peru

Fly into Jorge Chávez International Airport, Lima — overnight or early morning arrival.

Lima is one of the world’s great food cities — the birthplace of ceviche (the national dish), with a concentration of extraordinary restaurants (Central, ranked the world’s 6th best restaurant; Maido (Nikkei Japanese-Peruvian fusion); Astrid y Gastón; and dozens of extraordinary mid-range cevicherias) that makes it genuinely worth 2 days for food alone.

Day 1 — Miraflores and Barranco:

• Larcomar (the clifftop shopping center/restaurant complex above the Pacific — useful primarily for the extraordinary view: the Pacific directly below the 100-meter Lima cliffs, with paragliders launching from the park above)
• Parque Kennedy (the central park of Miraflores, the cats, the crafts market evening, the most liveable plaza in Lima)
• Barranco (Lima’s most beautiful neighborhood — the 19th-century wooden balconied houses, the Bridge of Sighs, the La Noche bar street, and the MATE museum (the Mario Testino photography collection) — walk the Bajada de Baños to the Pacific beach)

Day 2 — History and Food:

• Larco Museum (the most important collection of pre-Columbian Peruvian gold and ceramics in private hands — the Erotic Pottery Gallery (the most surprising permanent collection in any Lima museum) and the storeroom gallery (thousands of artifacts on open shelves, visible in their entirety) are extraordinary)
• Lunch at a cevicheria (the classic Lima lunch: ceviche (raw fish “cooked” in lime juice with ají amarillo peppers and choclo corn), tiradito (similar but sliced not diced, Japanese influenced), and causa (cold mashed potato terrine with avocado and seafood). Budget: S/35–60/person at excellent mid-range)

Days 3–6: Cusco and the Sacred Valley

Fly Lima–Cusco (1 hour, LATAM, $60–120). Altitude warning: Cusco is at 3,400m — acclimatization is not optional. Plan the first day for arrival, rest, and mild walking only. Altitude sickness (soroche) affects most visitors from sea level; the symptoms (headache, nausea, breathlessness) improve significantly after 24–48 hours.

Day 3 — Cusco City:

• Plaza de Armas (the main square, the cathedral (built over the Inca palace of Viracocha) and the Jesuit La Compañía de Jesús church competing for the most ornate Spanish colonial facade)
• Qorikancha (the Inca Temple of the Sun — stripped of its gold covering by the Spanish and a Dominican convent built on top, the extraordinary contrast of Inca mortarless stone (the finest stone-cutting precision in the world) and Spanish Baroque architecture is visible everywhere)
• San Pedro Market (the daily produce market used by locals — fresh fruit, fresh juices (S/2), and the best empanadas in Cusco)

Day 4 — Sacred Valley: The Sacred Valley (the broad agricultural valley between Cusco and Machu Picchu) contains multiple Inca sites along the Urubamba River:

• Pisac Market (Tuesday, Thursday, Sunday — the most authentic Andean market in Peru, extraordinary textiles, ceramics, and the agricultural terraces visible above the market town)
• Ollantaytambo (the best preserved Inca town in Peru — still lived in on its original street plan by local families, with the extraordinary Temple of the Sun under construction when the Spanish arrived (the Inca stonework visible still waiting for the final ashlar stones that were never placed))

Day 5 — Machu Picchu: Take the Vistadome train from Ollantaytambo to Aguas Calientes (1.5 hours, extraordinary river gorge passage as the train descends from the altiplano). Then bus to Machu Picchu from Aguas Calientes (30 minutes, $12 return).

The most important rules:

1. Book entrance tickets minimum 4–6 weeks ahead (the daily visitor cap is 4,044 — the site sells out regularly)
2. Choose the 6 AM opening slot — the morning mist and the first light hitting the citadel in the 6–8 AM window are extraordinary
3. The Inti Watana stone (the sundial/calendar stone — the only Inca stone in Peru not dynamited by the Spanish, visible because the site itself was unknown to the Spanish and therefore not destroyed)
4. Huayna Picchu (the steep pyramid peak above the main citadel, additional ticket required, limited to 400 people/day — the view from the top looking down at the citadel is the most photographed single image in South America)

Day 6 — Cusco Museums and Departure: The Inca Museum (Plaza de las Nazarenas, the finest collection of Inca artifacts in Cusco) and the Chocolate Museum (Cacao and Chocolate Museum, the complex history of Peruvian chocolate from cultivation to bar) before the evening train or flight from Cusco.

Days 7–10: Bolivia — Salt Flats and Altiplano

Fly Cusco–La Paz or Uyuni (multiple routing options; budget $80–150).

Uyuni Salt Flats (Salar de Uyuni): The largest salt flat in the world (10,582 km², the size of Jamaica) at 3,656m altitude — the extraordinary optical phenomena (the perfect mirror reflection of the sky when covered in thin water in the rainy season; the extraordinary perspective-free photography that the flat horizon enables in the dry season) and the remote landscape of the adjacent Reserva Eduardo Avaroa (pink flamingo lagoons, geysers, strange rock formations) make it among the world’s most extraordinary natural landscapes.

Best experience: 3-day guided 4WD tour from Uyuni town — Day 1: the salt flat, the Train Cemetery (abandoned 19th-century locomotives rusting in the desert), Isla Incahuasi (the giant cactus island in the middle of the flat); Day 2: the Eduardo Avaroa Reserve (Laguna Colorada, red due to algae and sediment, with thousands of flamingos wading; the Sol de Mañana geyser field (4,850m, 30 active thermal vents at dawn)); Day 3: Laguna Verde (the extraordinary green lake at the base of the Licancabur volcano near the Chilean border).

La Paz: Bolivia’s seat of government (the world’s highest capital city at 3,640m) — the Witches’ Market (El Mercado de las Brujas, where traditional healers sell dried llama fetuses, herbs, and amulets for traditional Andean ceremonies), the Mi Teleférico (the extraordinary cable car network connecting the altiplano neighborhoods of El Alto to the valley city below), and the cholita wrestling (the remarkable sport of Aymara women in traditional dress performing theatrical wrestling, Friday and Sunday evenings, extraordinary) all make La Paz more than a transit stop.

Days 11–14: Buenos Aires, Argentina

Fly La Paz–Buenos Aires (3–4 hours, LATAM or Aerolíneas Argentinas, $100–200).

Buenos Aires is one of the world’s great cities — described accurately as “the Paris of South America” (the architecture genuinely resembles Paris, the café culture is extraordinary, the fashion and arts scene is sophisticated) with the addition of the world’s finest beef (the asado culture, the parrillas, the provoleta, the empanadas) and the tango.

Day 11 — Palermo and Recoleta:

• Recoleta Cemetery (the extraordinary cemetery where Eva Perón is buried — the architectural elaborateness of the mausolea (miniature cathedrals, marble statuary, stained glass chapels) for Argentina’s aristocratic families is extraordinary)
• MALBA (the Latin American Art Museum of Buenos Aires, the finest collection of modern Latin American art, Frida Kahlo, Diego Rivera, and the extraordinary Argentine painters)
• Palermo Soho (the most interesting shopping and restaurant neighborhood, the afternoon feria artesanal of Plaza Serrano, the independent design shops)

Day 12 — San Telmo and La Boca:

• Mercado de San Telmo (the 1897 covered market in San Telmo — antiques, artisans, fresh food stalls, and the Sunday feria on the Plaza Dorrego)
• La Boca (the Caminito pedestrian alley with painted corrugated iron houses, the La Bombonera stadium (Boca Juniors), and the most tourist-concentrated area of Buenos Aires — good for one hour, not a neighborhood to linger in)

Tango: Buenos Aires is the birthplace of tango — the milonga (the social tango dance hall) is an extraordinary cultural experience. Recommended milongas: La Catedral (Almagro, informal, mixed ages, beautiful space in a converted warehouse), Confitería Ideal (the most historic milonga, a 1912 café-dance hall in the Teatro San Martín building), Salón Canning.

Day 13–14 — Rest or Day Trip: The Tigre Delta (40 minutes by train from Retiro station — the extraordinary labyrinthine delta of the Paraná River north of Buenos Aires, navigated by water taxi, with riverside restaurants and weekend beach houses of the porteño middle class) or Colonia del Sacramento, Uruguay (1-hour ferry from Buenos Aires to the most beautiful small colonial city in South America — the Portuguese-era cobblestone streets, the lighthouse, and the Bastion del Carmen). Day trips both valid; Uruguay round-trip is $30 (ferry).

Practical Information

Altitude Sickness: Coca tea (available everywhere in Peru and Bolivia, legal in these countries but a controlled substance in most others — do not attempt to bring it home) provides genuine mild relief. Acetazolamide (Diamox, 250mg twice daily starting 24 hours before ascent) is the pharmaceutical prevention — available over the counter in Peru and Bolivia, requires prescription in Europe/North America.

Payment: Peru: cash (soles) in markets, cards in restaurants; Bolivia: mostly cash (bolivianos); Argentina: cash (pesos) in many contexts; some restaurants accept only cash or offer a cash discount.

Safety: All three countries are broadly safe in tourist contexts. Violent crime is not typically directed at tourists; petty theft (phone snatching, bag theft) is the primary concern. Standard precautions (no visible expensive equipment, no phone use while walking in crowds, hotel safes for passports) are the appropriate response.

FAQ

Is Machu Picchu worth the expense and logistics? Unreservedly yes — it is among the handful of travel experiences that delivers on extraordinary expectations. The combination of the mountain setting, the impossibly precise Inca stonework, and the historical knowledge of how the city was built (on a purposely chosen site between two mountain peaks, specifically aligned for astronomical purposes, with a water supply system of exceptional engineering) makes it genuinely different from a standard archaeological visit.

Should I spend more time in Peru, Bolivia, or Argentina? Peru has the highest density of world-class experiences per day (Cusco, Machu Picchu, the Sacred Valley, Lima food scene) and would justify 10+ days on its own. Bolivia is extraordinary but physically demanding (the altitude) and less comfortable in infrastructure terms; 4–5 days is ideal. Buenos Aires is a city that rewards time — each additional day reveals more; 5–7 days is ideal for first-timers.
