Quick Summary: There’s no direct route from Arequipa to Salar de Uyuni — everyone goes via La Paz, and the question is how you get there. The scenic standard is Arequipa to Puno (around 6 hours), across the Kasani border to Copacabana, then on to La Paz, followed by an overnight bus or a one-hour flight south to Uyuni. Allow a minimum of two full travel days, ideally four or five with stops. The clever move for anyone still deciding: several Arequipa operators run a Colca Canyon day tour that ends in Puno instead of returning, which turns a travel day into a sightseeing day.
Arequipa is a natural jumping-off point for Bolivia. It’s the last big, comfortable, low-ish city before the Altiplano, and it sits at 2,335 m — high enough to start adjusting, low enough to sleep properly.
What it doesn’t have is a direct connection to Salar de Uyuni. The Salt Flats sit roughly 550 km south of La Paz, and La Paz is where every route funnels. Here’s how to plan the whole thing.
The shape of the journey
| Leg | Distance | Typical time | Notes |
|---|---|---|---|
| Arequipa → Puno | around 320 km | 5–6 hrs | Climbs from 2,335 m to 3,810 m |
| Puno → Copacabana (via Kasani border) | around 140 km | around 3 hrs incl. formalities | The tourist crossing |
| Copacabana → La Paz | around 155 km | around 4 hrs incl. Tiquina ferry | Puno to La Paz total is roughly 7–9 hrs door to door |
| La Paz → Uyuni | around 550 km | 9–12 hrs overnight bus, or about 1 hr flying | Separate booking whatever route you took |
Realistic total: two full travel days minimum, Arequipa to standing on the salt. Four to five days if you stop at Lake Titicaca and Copacabana, which most people should.
Your four route options
Option 1 — Arequipa → Puno → Copacabana → La Paz (the standard)
The default and the best-value version for most travelers. You break the journey at Puno for Lake Titicaca, cross at Kasani into Copacabana, and continue to La Paz.
Best for: first-time visitors, travelers who want to see Titicaca, and anyone who needs the altitude ladder.
The organized version of this corridor is Peru Hop on the Peruvian side connecting to Bolivia Hop at Puno — hotel pickups, bilingual hosts who handle the border windows, a viewpoint stop over the lake, and one flexible pass rather than four separate tickets. Passes from Puno to La Paz typically start around $49 and stay valid for a year.
Public buses run the same corridor and cost less on the ticket. They’re a solid choice if you speak Spanish and are comfortable with terminals — Tour Peru and Trans Titicaca both operate Copacabana–Puno services, generally leaving early morning from public terminals.
Option 2 — Colca Canyon tour ending in Puno
The underrated one. Several Arequipa operators run a full-day Colca Canyon tour that finishes in Puno rather than returning to Arequipa, for roughly $72–$110. You get the Cruz del Cóndor viewpoint, the Colca Valley villages, sometimes hot springs, and you arrive in Puno the same evening.
Starts are brutal — pickups from around 3:00 AM — and you’ll pay the Colca tourist ticket, around 70 soles for foreigners, on top. But it converts a plain transfer day into a proper sightseeing day, and Chivay at around 3,600 m is a useful altitude step.
Best for: travelers heading to Bolivia who also want Colca and don’t want to spend an extra day doing it.
Option 3 — Direct Arequipa → La Paz overnight via Desaguadero
Some services run through, crossing at Desaguadero rather than Kasani. Faster on paper, roughly 12–14 hours, and it skips Copacabana entirely.
Desaguadero is the busier, more industrial crossing, with heavy cargo traffic and less of a tourist-oriented setup. It also means going from 2,335 m to 3,640 m overnight without a stop, which is exactly the altitude jump worth avoiding.
Best for: travelers on a tight schedule who’ve already acclimatized elsewhere and speak enough Spanish to handle the border independently.
Option 4 — Flying
There’s no useful direct flight from Arequipa toward Uyuni; you’d route via Lima and La Paz, which is expensive and backtracks north. Flying makes sense only on the final leg: La Paz to Uyuni is about an hour, typically $80–$150 one way, against 9–12 hours overland.
Best for: travelers short on time on the last leg, or anyone who’s had enough of buses by La Paz.
| Route | Time Arequipa → La Paz | Cost | Best for |
|---|---|---|---|
| Via Puno and Copacabana, organized pass | 2 days with a Titicaca stop | Mid | First-timers, non-Spanish speakers |
| Via Puno, public buses leg by leg | 1.5–2 days | Lowest | Confident Spanish speakers |
| Colca tour ending in Puno, then onward | 2 days, one of them sightseeing | Mid | Travelers wanting Colca too |
| Direct overnight via Desaguadero | 12–14 hrs | Low–mid | Time-pressed, already acclimatized |
The border crossing in practice
Almost all travelers on this route cross at Kasani (Bolivia) / Yunguyo (Peru), near Copacabana. The two immigration buildings sit a few hundred metres apart and you walk between them. It’s the calmer of the two crossings and officers process foreign passports constantly.
What to have ready:
- Passport valid for at least six months, plus any Peruvian migration slip issued on entry
- Any visa or fee your nationality requires for Bolivia — verify with your own consulate, as requirements have shifted in recent years
- Small amounts of both soles and bolivianos. ATMs at borders are unreliable
- Passport and cash on your person, not in checked luggage
The most common mistake at this border is a missing stamp. There are two separate stops — Peruvian exit, Bolivian entry — and travelers occasionally leave without one. Check before you get back on the bus; it takes five seconds and is awkward to fix later.
Cross in daylight. Kasani generally runs daytime hours, and July and August queues can stretch well beyond an hour.
The final leg: La Paz to Uyuni
This is a separate booking regardless of how you reached La Paz — neither Peru Hop nor Bolivia Hop operates it.
- Overnight bus: roughly 9–12 hours, departing between about 8:00 and 10:00 PM, arriving at dawn. Todo Turismo is the long-standing tourist-oriented operator on this route. You arrive in time for the 10:00–10:30 AM Salt Flats departures and save a night’s accommodation.
- Flight: about an hour, typically $80–$150 one way. Fastest and most reliable.
- Bus and train via Oruro: slower, scenic, for travelers with time to spare.
Full detail is in our guide to travelling from La Paz to Uyuni.
Important for 2026: Bolivia’s national diesel shortage has cut bus fleet operability sharply and thinned out departures across the country. Book this leg one to three days ahead rather than weeks out, confirm the day before, and don’t build an itinerary where a single missed bus costs you a booked tour or flight.
Altitude: the thing to get right on this route
Arequipa to Puno is a bigger jump than it looks — from 2,335 m to 3,810 m in about six hours. Puno is higher than La Paz. Plenty of travelers feel worse in Puno than anywhere else on the trip, purely because it’s their first real altitude and they arrived quickly.
Practical handling:
- Spend at least two nights in Arequipa before going up
- Give Puno a night or two rather than transiting straight through
- Copacabana at around 3,840 m is another night at altitude — that’s a feature, not a delay
- Two nights in La Paz before heading to Uyuni
- Drink far more water than feels necessary; dry Altiplano air dehydrates you fast
- Coca tea and coca leaf are the standard local remedy and widely available
By the time you reach Uyuni at 3,670 m, you’ll have been above 3,000 m for the better part of a week. That’s what makes the Salt Flats enjoyable rather than endurable. More on altitude in our Salar de Uyuni info page.
FAQ
How long does it take to get from Arequipa to Salar de Uyuni?
The absolute minimum is about two full travel days: a day to reach La Paz via Puno, then an overnight bus arriving in Uyuni at dawn on the second morning, with the tour departing mid-morning. Realistically, most travelers take four or five days because they stop at Lake Titicaca and spend a night or two acclimatizing in La Paz. Compressing it to the minimum means arriving at 3,670 m having spent two days on buses, which is not the state you want to be in for a long day in a 4×4.
Should I go via Copacabana or straight to La Paz?
Via Copacabana, unless you’re genuinely short on time. The Kasani crossing is calmer and more tourist-oriented than Desaguadero, the route hugs Lake Titicaca, and Copacabana gives you access to Isla del Sol plus another night at altitude before La Paz. The Desaguadero route is faster and more industrial and skips all of that. The time saved is roughly half a day; what you give up is one of the better stretches of the whole corridor.
Can I book the whole Arequipa to Uyuni journey as one ticket?
No. Nobody sells a single through-ticket from Arequipa to Uyuni, and be sceptical of anyone claiming to. Pass-based services cover the Peru and Bolivia corridors up to La Paz on one flexible booking, but the La Paz–Uyuni leg and the Salt Flats tour itself are always separate. That’s normal, and it’s actually useful — it lets you decide in La Paz whether you want the bus or the flight, and which tour format suits your time.
Do I book my Uyuni tour in advance or on arrival?
Both work. Booking in Uyuni lets you visit agency offices, look at the vehicles, ask about group size and compare what’s included — genuinely useful, since price differences between operators usually reflect vehicle condition, driver experience and night-two accommodation. Booking ahead is worth it in July, August and February when demand is high, and if you’re arriving on a fixed schedule with no spare day. Comparison platforms such as FindLocalTrips are useful for seeing what’s on offer before you arrive.
Limitations
Journey times here are typical and vary with road conditions, weather and border queues, which lengthen considerably in peak season. Bolivian bus schedules and availability are unusually unreliable in 2026 due to the national diesel shortage, and fares changed substantially following a regulatory adjustment in January — older price guidance is out of date. Bolivia’s exchange rate has been floating since June 2026, so treat dollar figures as approximate and confirm prices in bolivianos. Border opening hours, procedures and visa requirements vary by nationality and can change without much notice; check your own consular guidance. Colca tour prices, entrance fees and whether a given operator runs the Puno-ending version change season to season — confirm directly before booking.
