Introduction
Peru and Bolivia sit next to each other on the map and share Lake Titicaca as a natural link between them, yet most travellers only visit one or the other. Combined, they deliver two of the most photographed landscapes in South America within the same trip — Machu Picchu's cloud-forest ruins and the mirror-flat, otherworldly expanse of the Salar de Uyuni salt flats. Twelve days is enough to do both properly, provided the altitude is respected rather than rushed through.
Why Peru and Bolivia Work as One Trip
Both countries share a high-Andean geography and Inca history, but the actual experiences on offer are strikingly different: Peru's highlights are historical and archaeological, built around Cusco and Machu Picchu; Bolivia's are geological and otherworldly, built around the Uyuni salt flats and the high-altitude deserts of the southwest. Lake Titicaca, straddling the border, is a natural and logical link between the two — most itineraries cross the border by bus along the lake, stopping on the Bolivian side at Copacabana.
How Long Do You Need?
Twelve days covers the essentials comfortably: four to five days around Cusco, the Sacred Valley and Machu Picchu, one to two days crossing via Lake Titicaca, and four to five days for La Paz and the Uyuni salt flats circuit. Ten days is workable if you tighten the Titicaca crossing to a single overnight stop in Copacabana. Fewer than ten days risks not allowing enough acclimatisation time at altitude, which is the single most common reason first-time visitors to this route have a miserable few days.
Getting Between Peru & Bolivia
The classic route runs Cusco to Puno (Peru's side of Lake Titicaca, roughly 6–7 hours by bus) then Puno to La Paz via Copacabana on the Bolivian side, another 6–7 hours including the border crossing, often broken into two days with a night in Copacabana to see the lake and Isla del Sol. Direct flights between Lima or Cusco and La Paz exist and save significant time if you would rather skip the overland Titicaca crossing, though you then miss one of the most scenic legs of the whole trip. From La Paz, the Uyuni salt flats are reached either by overnight bus (around 10–12 hours) or a short flight to Uyuni town itself.
Cusco and the Sacred Valley
Cusco itself, the former Inca capital, sits at roughly 3,400m and deserves two to three acclimatisation days before attempting Machu Picchu or any strenuous activity — this is not optional if you want to avoid altitude sickness ruining the rest of the trip. Use these days for the city's colonial-Inca architecture and a day trip into the Sacred Valley, which sits lower than Cusco and offers Pisac's ruins and market, Ollantaytambo's fortress, and the Maras salt pans, a striking and much less crowded photo opportunity than Uyuni for travellers who cannot make it to Bolivia.

Machu Picchu: Getting the Logistics Right
Machu Picchu tickets sell out weeks to months in advance during peak season (June to August) and must be booked for a specific entry time slot alongside a specific trail or circuit through the site — this is not something to leave until arrival in Cusco. Most visitors reach the site via train from Ollantaytambo to Aguas Calientes (around 1.5–2 hours) followed by a short bus up to the entrance, rather than the multi-day Inca Trail, which requires permits booked months ahead and is capped at a limited number of hikers per day. A pre-dawn start from Aguas Calientes gets you inside before the largest tour groups arrive.
La Paz and the Salar de Uyuni
La Paz, the world's highest administrative capital at over 3,600m, is a dramatic, chaotic city best experienced via the Mi Teleférico cable car network, which doubles as genuinely spectacular urban transport and viewpoint in one. The real reason most travellers come to Bolivia, though, is the Salar de Uyuni — the world's largest salt flat, an almost perfectly flat white expanse that becomes a mirror reflecting the sky during the wet season (roughly December to April), producing some of the most surreal photographs available anywhere on earth. Multi-day tours from Uyuni town combine the salt flats with the coloured lagoons and geysers of the surrounding high-altitude desert.
Budget: How Much Does This Route Cost?
Peru runs $40–70 per day mid-range, rising to $80–120 per day around the Machu Picchu leg specifically, where train tickets and entrance fees add up quickly. Bolivia is noticeably cheaper at $30–55 per day, including the multi-day Uyuni salt flat tour, which is typically priced as an all-inclusive package ($150–300 for a three-day tour covering transport, accommodation and meals). A twelve-day trip across both countries, mid-range throughout, is realistically achievable for $1,300–2,000 per person.
Altitude: What First-Timers Get Wrong
This route spends most of its time above 3,000m, and La Paz itself sits above 3,600m — high enough that altitude sickness is a real risk, not a theoretical one. The most common mistake is flying directly into Cusco or La Paz and attempting a full day of sightseeing immediately; the correct approach is two full acclimatisation days with minimal exertion before anything strenuous. Coca tea, widely available and culturally normal throughout the Andes, genuinely helps with mild symptoms. Anyone with a history of altitude issues should speak to a travel doctor about preventive medication (acetazolamide) before the trip rather than after symptoms start.
Building Your Peru & Bolivia Itinerary with FigFinder
A Peru-and-Bolivia trip needs careful sequencing around altitude acclimatisation, Machu Picchu ticket timing, and the Titicaca border crossing — get any of these wrong and it costs days of the trip, not hours. FigFinder builds the complete version in seconds: tell it your dates, budget and departure city, and it sequences Cusco, the Sacred Valley, Machu Picchu, Lake Titicaca, La Paz and the Uyuni salt flats with acclimatisation days built in, plus a Day-Zero Survival Kit covering altitude preparation, visa requirements and packing for both highland and salt-flat conditions.
