Cusco to La Paz (Bolivia): routes, border crossing and tips

The Cusco–La Paz route is a South America classic: it crosses the altiplano, skirts Lake Titicaca and crosses the Peru–Bolivia border. You can do it in one go by bus (a long day or a night) or, much better, with stops in Puno and Copacabana.

The two main routes

• Via Desaguadero: the most direct route. Cusco → Puno → Desaguadero border → La Paz. About 12–15 hours in total depending on connections and formalities.
• Via Copacabana: Cusco → Puno → Kasani border (near Yunguyo) → Copacabana on Lake Titicaca → ferry across the Strait of Tiquina → La Paz. Slower but prettier, and lets you visit Isla del Sol.

• Cusco to Puno and Lake Titicaca: bus, tourist bus, train or plane

Buses and stops

There are direct buses from Cusco to La Paz and combinations changing in Puno. Tourist services that stop in Puno and Copacabana let you split the journey. Book with formal companies and check whether the ticket includes assisted border formalities.

Crossing the border

• You'll exit Peru (immigration) and enter Bolivia on foot with your passport, then get back on the bus.
• Bolivia's entry requirements depend on your nationality: some need a visa or advance paperwork. Check official information from Bolivia's foreign ministry or consulate before travelling.
• Carry some cash in US dollars or bolivianos for first expenses; only change small amounts at the border.
• Keep any entry documents you're given.

• Money in Cusco: soles, ATMs, exchange offices and cards

Flights

Flights between Cusco and La Paz usually connect (typically in Lima). Faster than the bus but pricier, and you miss Titicaca.

Altitude

La Paz is at about 3,600 m and El Alto, where the airport is, above 4,000 m. Coming from Cusco and Puno you'll be acclimatised, but take it easy.

A recommended staged itinerary

1. Day 1: Cusco–Puno (direct or tourist bus). Night in Puno.
2. Day 2: Uros islands in the morning; in the afternoon, bus to Copacabana via Kasani. Night in Copacabana.
3. Day 3: boat trip to Isla del Sol, with ruins and trails above the lake. Night on the island or in Copacabana.
4. Day 4: Copacabana–La Paz (about 3–4 hours), including the Strait of Tiquina crossing: passengers cross by launch and the bus on a raft.

This way the journey stops being a transfer and becomes one of the highlights of the trip.

Money, phone and time zone

• Currency: Bolivia uses the boliviano. There are ATMs in La Paz and Copacabana, but they don't always accept every card; carry some cash.
• Phone: your Peruvian SIM may not work or may be expensive on roaming; consider a local SIM or eSIM.
• Time: Bolivia is one hour ahead of Peru. Factor it into bus and flight connections.
• Border hours: border posts have opening hours; buses are scheduled to cross within them.

First steps in La Paz

La Paz fills a canyon at about 3,600 m, and El Alto, on the altiplano above, is over 4,000 m. A few ideas for your first days:

• Mi Teleférico: the urban cable-car network linking La Paz and El Alto works as public transport and is one of the largest in the world. As well as practical, it gives spectacular views of the city and of Illimani.
• Plaza Murillo: the political centre, with the cathedral, the Government Palace and the Legislative Assembly.
• Witches' Market: in the streets around Sagárnaga and Linares, stalls of herbs, amulets and traditional Andean offerings.
• Valle de la Luna: eroded clay formations south of the city, easy to visit in half a day.
• Feria 16 de Julio in El Alto: a huge street market on Thursdays and Sundays; go without valuables and stay alert.

Copacabana in brief

If you choose the lake route, Copacabana deserves at least one night. Its basilica houses the Virgin of Copacabana, Bolivia's patron saint, and in front of it cars and trucks decorated with flowers are blessed, a memorable scene. Climb Cerro Calvario at sunset for views over the lake; boats to Isla del Sol leave from the harbour. Remember that in Copacabana you will already be paying in bolivianos.

Before you go

eSIM for Peru

Land connected: install an Airalo data eSIM before you travel and switch it on when you land. Check first that your phone supports eSIM and is unlocked.
