Andorra National Bus Guide 2026: Fare Zones, Transfers, Passes, Lines, and Night Bus

Andorra has no internal railway, so the national bus network matters more than it first appears. It links Andorra la Vella with Sant Julià de Lòria, Encamp, Soldeu, Pas de la Casa, Arinsal, Ordino, La Massana, Escaldes-Engordany, and ski access points.

This guide is for travelers deciding whether a single ticket, return ticket, multi-ride card, weekly pass, or night bus will fit a short stay. The main rule is to plan by zone and line, then check the current line page before you leave, because spring, ski season, road works, festivals, and night-bus calendars can change the exact timing.

What to know first

The official fare page lists a Zone 1 single ticket at €1.90, a Zone 2 single at €3.45, and a Zone 3 single at €4.80.
Children under three travel free, according to the official tariff notes.
Transfer validity is time-limited: Zone 1 gives 60 minutes, Zone 2 gives 70 minutes, and Zone 3 gives 90 minutes.
Transfers are allowed between different lines in the validated zone, regardless of concessionaire, if you stay within the time limit and keep the same direction of travel.
Return tickets expire 15 days after first validation, so they are useful for short trips but not for open-ended future travel.
Tickets can be bought at the National Bus Station offices, directly on the bus, and through the MOU-T-B mobile app.
The Bus Nocturn has a 2026 calendar; two night services are assured every day, with fuller Friday, Saturday, holiday-eve, and event-night operation.

Fare zones and ticket choice

The official tariff page is organized by zones. For a short visitor, the most useful starting point is the single fare: Zone 1 is €1.90, Zone 2 is €3.45, and Zone 3 is €4.80. Use these as planning figures, then check the zone map on the same official page before you travel to a parish farther from the capital.

A return ticket is different from two loose single tickets. The official note says the return ticket expires 15 days after the first validation. That makes it practical for a same-trip or same-stay outing, but it is not something to buy for an uncertain later visit.

The tariff notes also matter if you are traveling with a family or using a reusable pass. Children under three ride free. The deposit for a magnetic or contactless pass support has a maximum price of €3, which means the first purchase of a pass may cost more than the printed fare alone.

Passes, transfers, and what validation means

The official fare page explains several pass types. T-10, T-20, T-30, and T-40 are multi-person products, so more than one person can use the same card. Temporal passes such as weekly, monthly, semiannual, and annual products are activated on first use.

For travelers, the transfer rule is the small detail that changes the day. In Zone 1, a validated trip gives 60 minutes. In Zone 2, it gives 70 minutes. In Zone 3, it gives 90 minutes. During that window, the user can move between lines in the validated zone, even if the operator changes, as long as the transfer stays in the same direction.

That means you should not treat a transfer as unlimited hop-on, hop-off travel. If you stop for lunch or shopping, the validity window may run out. If you change direction, the official transfer rule may no longer protect the trip.

Line choice from Andorra la Vella

The Visit Andorra route page and bus.ad list the main regular lines. L1 links Escaldes-Engordany and Sant Julià de Lòria. L2 links Andorra la Vella and Encamp. L3 links Andorra la Vella and Soldeu. L4 links Andorra la Vella and Pas de la Casa.

The northern and western valleys use other lines. L5 links Andorra la Vella and Arinsal. L6 links Andorra la Vella, Ordino, and La Cortinada. L7 links Andorra la Vella, La Massana, and Ordino. The express bus links Andorra, Escaldes-Engordany, and Sant Julià de Lòria more directly.

Bus.ad says Coopalsa manages L2 through L7, while Autocars Nadal manages L1 and the express bus. The site also says the combined network has more than 750 stops across the Principality. In ski season, special services can increase frequencies and help reach ski slopes or gondolas in Encamp, Canillo, La Massana, and Arcalís.

Timetable checks and mountain-route risk

Do not assume every mountain route runs like a city shuttle every day. The L4 page, for example, lists Andorra la Vella to Pas de la Casa from 06:25 to 21:25 every 30 minutes, with additional Monday-to-Saturday services at 06:35 and 22:00. From Pas de la Casa, it lists service from 06:40 to 21:40 every 30 minutes.

The L3 page shows why checking the exact line matters. Under the current timetable shown on bus.ad, the Andorra la Vella to Soldeu line has morning and afternoon/evening weekday bands, Saturday bands, and no Sunday service. A traveler who only reads a general route list can miss that kind of detail.

Bus.ad also posts timetable change notices. A 2026 notice says new spring timetables took effect from Monday, 13 April, and that changes appear when users click each line. If a line does not show a new timetable label, the notice says that line has not changed.

Night bus and late returns

The Bus Nocturn is useful, but it is not the same as a metro running all night. Bus.ad publishes a 2026 night-bus calendar and says two night services are assured every day of the year. It also says the night bus is activated every Friday and Saturday night, on nights before public holidays, and on selected festival or event nights.

The Friday, Saturday, holiday-eve pattern is broader. The page lists service from 22:30 to 05:30 for those nights. It also separates BN1, BN2, and BN3 routes, covering Sant Julià de Lòria, Canillo, Ordino, Arinsal, and the National Bus Station area.

For a traveler, the practical decision is simple. Use the night bus when the published route matches your valley and you have checked the exact night. If you are returning from a late dinner, festival, ski-area event, or cross-border arrival, do not assume your daytime line number has a direct night equivalent.

Common mistakes

The first mistake is buying a single ticket for every movement without checking whether a timed transfer would cover the connection. If you stay within the same direction and time window, the system may be more flexible than it looks.

The second mistake is assuming the capital timetable applies to Soldeu, Pas de la Casa, Arinsal, or Ordino. Mountain and valley routes can have seasonal frequencies, extra ski services, or no-service periods on specific days.

The third mistake is planning the last return without a backup. Road works, public events, and route modifications appear in the Informem notices on bus.ad. On a small mountain network, a temporary stop cancellation can matter.

Who should choose which ticket or line

Choose a single ticket if you are making one short movement and will not transfer after the validity window.
Choose a return ticket if you know you will come back within the 15-day validity period after first use.
Choose a T-10, T-20, T-30, or T-40 if several people will use shared rides and the zone math makes sense.
Choose a weekly or monthly pass if buses will be your main transport during the stay and you understand first-use activation.
Choose the express bus for the Sant Julià to Escaldes corridor when you want a more direct route.
Choose L4 for Pas de la Casa planning, but check the exact day and direction before relying on the last service.
Choose Bus Nocturn only after checking the 2026 calendar and the route for that specific night.

What to check before you go

Check the tariff page before buying. Fares, zone maps, pass rules, child fares, deposits, and transfer validity all live there, and those details affect whether a pass is worth buying.

Check the line page before leaving the stop. Visit Andorra gives the route overview, while bus.ad gives current line pages, frequencies, seasonal notices, and disruptions. For L3, L4, ski routes, and night returns, this is not optional.

Check ticket sales options if you arrive on a Sunday or holiday. The official sales page lists the National Bus Station offices, on-board purchase, and the MOU-T-B app. It also lists the office schedule as Monday to Saturday from 08:00 to 20:00, with Sundays and holidays closed.
