Quick Summary: Crossing from Peru into Bolivia by bus means two separate immigration stops — exit Peru, walk or drive a short distance, enter Bolivia — with a passport, a completed SIGEMIG registration and some patience. Kasani (for Copacabana) is the calmer crossing; Desaguadero is the faster direct route to La Paz. Cross in daylight, allow two to three hours of buffer, and remember that US citizens no longer pay the old $160 visa fee.
For travelers heading to Salar de Uyuni, the border day is usually the part of the trip they worry about most. It’s the day with the most moving parts: two immigration offices, a currency change, a bus that may or may not wait for you, and a language you might not speak.
In practice it’s a queue, a stamp, a short walk and another queue. Here’s exactly how it goes, and what actually causes problems.
Before you leave: three things to do
- Complete SIGEMIG. Bolivia now asks every foreign visitor, regardless of nationality, to complete a free online migration pre-registration before arrival. It takes about ten minutes, opens 30 days before your travel date and produces a QR code. Screenshot it — mobile signal at both crossings is patchy.
- Check your passport validity. Bolivia requires at least six months of remaining validity at entry. This is checked, and travelers have been turned back over it.
- Get small cash in both currencies. You’ll want small Peruvian soles for the exit side and small bolivianos or US dollars for the entry side. Photocopies, snacks, toilets and taxis all want small notes.
Which crossing you’ll use
| Kasani / Yunguyo | Desaguadero | |
|---|---|---|
| Leads to | Copacabana, then La Paz | La Paz directly |
| Character | Small, tourism-oriented, lakeside | Large, busy, heavy freight traffic |
| Typical hours | Roughly 07:00–20:00 on the Peru side | Border post 24 h; CEBAF complex approx. 08:00–20:00 |
| Walking distance between posts | A few minutes | Across a bridge, longer and busier |
| Best for | First-time crossers, anyone stopping at Lake Titicaca | Confident travelers wanting the fastest La Paz run |
Most organized services and most tourists use Kasani. Most public buses running Puno to La Paz direct use Desaguadero.
Step by step: the border day
1. Arrive at the Peruvian post
Your bus stops on the Peru side. Take everything valuable with you; leave the big backpack on the bus if the driver says so, but never leave your passport, phone or money.
2. Exit Peru
Queue at Peruvian immigration. You hand over your passport, they check your entry record and stamp you out. There is no exit fee. If you overstayed your Peruvian permitted days, this is where you’ll be asked to pay a fine, and it’s calculated per day — worth checking your entry stamp before you get to the window rather than discovering it in the queue.
3. Cross the physical border
At Kasani this is a short walk of a few minutes past the arch. At Desaguadero it’s a walk across the bridge over the Desaguadero River. Your bus usually meets you on the other side. Keep the group in sight.
4. Enter Bolivia
Queue at Bolivian immigration. Present your passport and SIGEMIG QR code. You may be asked for your accommodation address, so have it written down. The officer stamps you in — read the number of days written on the stamp. It is frequently written as 30 days even though most nationalities are entitled to 90 days per calendar year, and it can be extended at immigration offices in La Paz, Santa Cruz, Cochabamba or Sucre.
5. Reboard and continue
At Kasani you continue to Copacabana, roughly 10 minutes away. At Desaguadero you continue toward La Paz, around 2 to 2.5 hours.
Realistic total: one to three hours, depending on how many buses arrived just before yours.
The 2026 rule change worth knowing
The single biggest update for travelers is that Bolivia removed the visa requirement for United States citizens on 1 December 2025, alongside South Korea, South Africa, Israel, Bulgaria, Malta, Romania and the UAE. The U.S. Embassy in La Paz confirmed it in early December 2025.
That means the old routine — $160 in crisp untorn bills, two passport photos, printed hotel bookings and bank statements — no longer applies to Americans. Plenty of websites and even some tour desks still describe it. If someone at the border tries to charge a US passport holder a tourist visa fee, that is worth questioning politely and calmly.
Citizens of the UK, EU countries, Canada, Australia, New Zealand, Japan and most of South America were already visa-exempt and remain so. Some African and Asian nationalities still require a visa either at the port of entry or in advance from a Bolivian consulate — check with the nearest Bolivian embassy well before you travel.
Organized bus vs public bus on border day
Border day is the single clearest case where the organized services earn their price difference.
- Bolivia Hop / Peru Hop. Bilingual staff hand out the forms on board, explain the sequence before you get off, point you at the right window, and hold the bus until everyone has cleared both posts. Pickups are at hotels rather than terminals. Bolivia Hop runs the Bolivian side including Copacabana and La Paz; Peru Hop covers Peru with the same model.
- Public buses. Cheaper per seat, frequent, and completely fine if you know what you’re doing. The risks are practical rather than dramatic: no explanation of the process, everything in Spanish, and a real history of buses continuing before all passengers have cleared immigration. If you take one, tell the driver’s assistant your seat number and confirm the departure time before you walk off.
The wider price comparison is the one people get wrong. A public bus ticket looks meaningfully cheaper until you add the taxi to the Puno terminal, the taxi from the La Paz terminal, an hour of waiting, and the occasional forced overnight when a connection falls through. Organized services bundle those into one predictable number. Public buses are still the better choice for fluent Spanish speakers who want to travel directly and don’t mind managing the pieces.
Mistakes that actually cause problems
- Crossing late in the day. Offices thin out, onward transport dries up, and border towns are not places you want to be stuck overnight. Aim to cross between 10:00 and 15:00.
- Not checking the days on your Bolivian stamp. Assuming 90 days and receiving 30 is the most common cause of an accidental overstay.
- Arriving without SIGEMIG. It won’t usually bar entry, but it is the most common cause of delays.
- Only carrying large notes. Nothing at a border breaks a 200-boliviano note cheerfully.
- Booking a tight onward connection. A same-day flight from La Paz after a morning border crossing is a plan that works right up until it doesn’t.
After the border: getting to Uyuni
The border is not the destination. From La Paz you still have a 9 to 12 hour overnight bus, a 1 hour flight, or a bus-and-train combination via Oruro to reach the salt flats. Departure times, seat classes and costs are covered in the La Paz to Uyuni guide, and the country-by-country overview is in how to get to Salar de Uyuni.
One practical note: withdraw bolivianos in La Paz. The salt flats circuit is cash-only for park fees, and there are no ATMs once you leave Uyuni town.
FAQ
How long does the Peru-Bolivia border crossing take by bus?
Plan for one to three hours between stepping off the bus on the Peru side and reboarding on the Bolivian side. Quiet mid-morning crossings can be done in under an hour; a busy period when three buses arrive together can stretch past two hours. The variable is almost entirely queue length, not paperwork, so the practical fix is timing — cross late morning rather than at dawn or dusk.
What documents do I need at the border in 2026?
A passport valid for at least six months beyond your entry date, a completed SIGEMIG online pre-registration with its QR code, and your Bolivian accommodation address. A yellow fever vaccination certificate may be requested, particularly if you’re continuing to lowland regions east of the Andes. Most nationalities do not need a visa, but travelers from countries still in Bolivia’s visa-required groups should arrange one before travel.
Can I cross the Peru-Bolivia border on foot without a bus?
Yes. At both Kasani and Desaguadero you can walk across independently, and many travelers do — arriving by collectivo from Yunguyo or Desaguadero on the Peruvian side, walking through both immigration posts, and picking up onward transport in Copacabana or on the Bolivian side. It is legal and common. It is also the version with the most moving parts, so it suits confident travelers with reasonable Spanish rather than first-timers.
Is the border safe?
Both crossings are generally safe in daylight, with normal precautions. The genuine risks are opportunistic rather than violent: bag theft while you’re distracted at a window, unofficial “helpers” charging for free services, and poor exchange rates from street money changers. Keep your passport and money on your body, decline help you didn’t ask for, and change only a small amount at the border to cover immediate costs.
What happens if my bus leaves without me?
It happens, mainly with public services. If it does, both border towns have onward transport: collectivos and minibuses run from Kasani to Copacabana constantly, and from Desaguadero to La Paz through the day. You’ll pay again and lose a couple of hours, but you won’t be stranded. The way to avoid it entirely is to travel with a service that has a stated policy of waiting for all passengers, or to confirm the departure time and your seat with the driver before you leave the bus.
Limitations
Border hours, procedures and entry requirements can change with little notice, and Bolivia’s immigration rules were substantially revised in December 2025 and are still being refined. The SIGEMIG system, the visa-exempt country list and the operating hours at Kasani and Desaguadero are all worth verifying in the week you travel rather than relying on any secondary source, including this one. Verify entry requirements with your own consulate or the nearest Bolivian embassy, and check current road and security conditions — the U.S. State Department and Government of Canada publish updated Bolivia advisories. Road blockades affected this corridor for several weeks in mid-2026, so keep a spare day in your plan.
