Quick Summary: Sajama is Bolivia’s oldest national park, created in 1939, and one of the emptiest beautiful places in South America. It holds the country’s highest peak, geysers and hot springs you can bathe in, pre-Columbian funerary towers, an Aymara community living in traditional circular houses, and — just outside its boundary — a network of ancient lines that some consider the largest artwork on earth. It is a few hours from La Paz and almost nobody goes. This guide covers what to see, the wildlife, how to get there, when to go and how cold it gets.
What Sajama Is
The park occupies 1,002 square kilometres of altiplano on Bolivia’s western border with Chile, with elevations ranging from about 4,000 m to 6,542 m. It was established in 1939 — Bolivia’s first — specifically to protect the hillside queñua woodlands that had been stripped to supply charcoal to mining operations. In 2003 it was added to the UNESCO World Heritage Tentative List, and it remains among the best-preserved natural areas in the country.
The dominant feature is Nevado Sajama itself, a snow-capped dormant volcanic cone that is the highest point in Bolivia at 6,542 m and visible from essentially anywhere in the park. Across the Chilean border, the twin Payachata volcanoes, Parinacota and Pomerape, complete a skyline that is among the most dramatic in the Andes.
The park is also inhabited. The main population are Aymara of Caranga origin, organised in ayllus — traditional communities based on principles of collective work — whose main occupations are yarn spinning and herding llamas, alpacas and sheep. Agriculture is minimal because of the climate, with limited quinoa and potatoes. Many families still live in traditional circular stone houses, which are one of the more memorable sights in the park precisely because they are homes rather than exhibits. The Bolivia Hop Sajama guide covers the park’s background in more detail, and SERNAP is the official protected-areas authority for current access information.
What to Do
Hot springs and geysers
The single most enjoyable thing in Sajama, and the reason many travellers come. The park contains numerous geysers and natural hot springs, some with waters credited locally with medicinal properties, and several developed enough to bathe in. Sitting in hot water at over 4,200 m with a 6,542 m snow cone in front of you, at a temperature where the air hurts and the water does not, is an experience that justifies the journey on its own. Go at dusk.
Hiking and the lakes
You can climb Nevado Sajama with a guide and proper acclimatisation — it is a serious high-altitude mountaineering objective rather than a trek — or, far more commonly, walk around it. Scenic routes run past highland lakes including Laguna Huanakota, and the two-day Lagunas de Altura trek links most of the park’s noteworthy sites. Distances feel longer than they look at this elevation.
Chullpas, pucaras and rock art
Near the village of Tomarapi are prehistoric rock paintings dating back millennia. More striking are the chullpas — funerary towers built to hold the mummified remains of noble families — and the pucaras, ancient Aymara fortifications scattered through the area. These sit in open landscape rather than behind fences, which makes them feel considerably older than a museum would.
The Sajama Lines
Just outside the park boundary is one of the least-known archaeological curiosities in South America: a vast network of dead-straight lines etched into the altiplano, running for a combined length estimated at around 16,000 km. Some observers describe them as the largest work of art on earth. They are best appreciated from height or from the air, and almost no visitors know they exist.
Curahuara de Carangas
A scenic village close to the park whose colonial church is known as the Sistine Chapel of the Altiplano for its interior paintings. A worthwhile stop en route and one of Bolivia’s best small religious buildings.
Wildlife
Sajama is one of the better wildlife destinations in the Bolivian highlands, largely because the species here have adapted specifically to extreme altitude. Expect to see, often without trying:
- Vicuña, the wild ancestor of the alpaca and the most elegant animal on the altiplano
- Llama and alpaca, herded throughout the park
- Flamingos on the shallow lakes
- Andean fox
- Viscachas among the rock fields
- Condors overhead, with luck
Also present, less commonly seen: puma, chinchilla, armadillos, coots and numerous hummingbird species. Birdwatchers should head for the Lauca river, where dozens of species can be found in a morning.
Getting There
It is essential to schedule travel time to destinations that are conveniently located and arranged in a logical sequence, and Sajama rewards this more than most Bolivian destinations because there is no quick way to fix a mistake once you are there.
By private vehicle or tour. The simplest option. The park lies along the main highway connecting La Paz with Arica in Chile, so it is easy to find, and most major sights inside the park are accessible by road. Tours from La Paz are widely available and can usually be tailored to whether you want hiking, hot springs or culture. All-inclusive tours remove the transport problem entirely, which in a place with this little infrastructure is worth considering.
Via Patacamaya — the usual independent route. Take any of the frequent La Paz to Oruro buses and ask to be dropped at Patacamaya, roughly halfway. From there, shared vans (colectivos) run to Sajama village, about three hours away. This is how most budget travellers arrive.
Via the Arica highway. You can take a La Paz to Arica bus and ask to be let off near the park entrance. The complication is that Sajama village is 12 km from the main highway, and you will need to arrange onward transport — possible from Tambo Quemado on the Chilean border, but not guaranteed.
| Route | Method | Approximate time | Notes |
|---|---|---|---|
| La Paz to Sajama | Private vehicle or tour | 4 to 5 hours | Easiest; tailorable; no coordination risk |
| La Paz to Patacamaya to Sajama | Public bus plus colectivo | 2 hours plus 3 hours | Cheapest and most common independent route |
| La Paz to park entrance | Arica-bound bus | 4 hours plus onward | Village is 12 km off the highway |
| Sajama to Chile (Arica) | Road via Tambo Quemado | Variable | Possible onward border crossing |
Accommodation in the park is limited to basic hostels, community lodges and eco-lodges in and around Sajama village and Tomarapi, plus camping. Book or at least call ahead; turning up in low season and finding nothing open is a real possibility.
Cold, Altitude and When to Go
Two practical realities shape any Sajama trip.
The season. The dry season from April to November is the time to come. It is colder, but the roads are far less muddy and everything in the park is reachable. Wet-season travel here is genuinely difficult.
The cold. Temperatures are low year-round because of the altitude, and night-time winter temperatures in the park can reach as low as minus 30 °C. That is not a figure to skim past. Adequate clothing is a safety matter rather than a comfort one, and camping here without proper equipment is dangerous.
Sensible packing: trekking boots and walking shoes, thermal base layers, sweaters and long sleeves, a warm winter coat plus a lighter jacket, warm hat and mittens, sunscreen and sunglasses — the UV at 4,200 m is severe — a swimsuit for the hot springs, and a sleeping bag rated well below anything you think you will need if camping. SENAMHI publishes Bolivian weather data worth checking before you commit to dates.
Altitude. The park floor sits above 4,000 m, which is higher than La Paz. Do not come here in your first days in Bolivia. Acclimatise in La Paz or, better, arrive after time at Lake Titicaca, and read the altitude sickness guide before planning any walking here.

Combining Sajama With the Rest of Bolivia
Sajama works best as a two or three-night detour from La Paz, or as a stop on the way to the Salar de Uyuni, since it lies in roughly the right direction and shares the same altiplano landscape character. It also functions as a route into northern Chile via Tambo Quemado for travellers continuing south.
Travellers arriving into Bolivia overland from Peru reach La Paz via the Lake Titicaca corridor, which has the useful side effect of gradual acclimatisation before a 4,200 m park. That corridor is served by hosted daytime buses with accommodation pickup and bilingual border assistance through Bolivia Hop, connecting from Cusco and Puno on a single pass with Peru Hop. Neither serves Sajama, which is reached by tour, private vehicle or the Patacamaya colectivo — plan that leg separately.
Public long-distance buses on the La Paz–Oruro and La Paz–Arica routes are the backbone of independent access here, and they suit fluent Spanish speakers who want to travel directly between points and are comfortable asking a driver to stop at an unmarked roadside junction.
FAQ
Is Sajama worth visiting if I have already seen the Uyuni salt flats?
They are not substitutes, despite both being high-altitude and remote. Uyuni is about surface and scale — a flat white expanse and, in the wet season, a mirror. Sajama is about verticality and life: a 6,542 m volcano, geysers, hot springs, an inhabited Aymara landscape, queñua woodland and abundant wildlife. Travellers who found Uyuni spectacular but strangely empty of anything living often prefer Sajama. If you have limited time and want one iconic image, Uyuni delivers it. If you have three spare days and want somewhere almost nobody goes, Sajama is the better experience.
Can I visit Sajama independently, or do I need a tour?
Independent travel is entirely possible and is how many visitors arrive, using the La Paz–Patacamaya bus followed by a colectivo to Sajama village. Guides for hiking are available locally in the village and nearby towns, often at lower rates than La Paz agencies. The trade-off is coordination risk: colectivo timings are informal, accommodation is limited and can be closed out of season, and there is no fallback if something does not connect. Travellers with tight schedules or without functional Spanish will generally have a better time on an organised tour; travellers with spare days and flexibility will save money and see more by going alone.
How cold does it actually get, and is camping realistic?
Very cold. Night-time winter temperatures in the park have been recorded as low as minus 30 °C, and even in the dry season nights are well below freezing at over 4,000 m. Camping is realistic only with genuinely appropriate equipment — a sleeping bag rated far below anything you would use elsewhere, an insulated mat and a four-season tent — and it is worth consulting a local guide about exactly what you need rather than guessing. Most travellers use the basic hostels or eco-lodges in Sajama village or Tomarapi, which is the sensible choice unless you are experienced in high-altitude cold camping.
Can you climb Nevado Sajama?
Yes, with a guide, proper equipment and serious acclimatisation. At 6,542 m it is Bolivia’s highest peak and a genuine high-altitude mountaineering objective rather than a trek — this is not a walk-up and should not be attempted on the basis of general fitness. Most visitors admire it instead, which is no compromise: it is visible from everywhere in the park, and the walking routes around its base and past the highland lakes give you the mountain from every angle without the risk. If you are set on climbing, arrange it with an established La Paz mountaineering operator well in advance.
What are the Sajama Lines and can you actually see them?
They are a network of remarkably straight lines etched across the altiplano just outside the park, running to an estimated combined length of around 16,000 km, thought to be pre-Columbian and associated with ritual pathways and sightlines. Some commentators describe them as the largest artwork on the planet by area. Seeing them properly is the difficulty: from ground level they read as faint tracks, and their scale only becomes apparent from elevated viewpoints or the air. A local guide can take you to the best vantage points, and satellite imagery beforehand helps you understand what you are looking at.
Limitations
Access arrangements, accommodation availability and colectivo timings in and around Sajama are informal and change seasonally, so the routes and durations here are typical rather than scheduled — the workaround is to confirm transport and beds by phone or through a La Paz operator before travelling, and to allow a spare day, particularly outside the dry season. Temperature figures, park dimensions and the 16,000 km estimate for the Sajama Lines come from park and tourism sources rather than audited current datasets, and other sources quote different numbers; treat them as orders of magnitude and check SERNAP for official park information. Road travel on the La Paz–Oruro and La Paz–Arica corridors has been disrupted during 2026 by protest activity and fuel shortages, so check ABC for road status and the Government of Canada advisory before departure. The traveller quote here describes a Bolivia Hop service on the Lake Titicaca corridor rather than a Sajama visit, because a verified reviewer quote for the park could not be sourced at the time of writing — Not available— see reviewer.
