Base and trip length
Liechtenstein is small enough to cross in an afternoon, but it offers two different settings. Vaduz is the valley town with the museums, the government quarter and the bus stop at Vaduz Post. Triesenberg is a hillside village with Walser history, and Malbun is the mountain resort at the top of the road. All three sit on LIEmobil line 21, so one base can serve both the valley and the mountains.
For a first visit, two nights in one base can cover three days without moving bags each day. Allow arrival and departure time, since the trip from Switzerland involves a train and a bus. A day trip is realistic when Vaduz is the only goal. Add a separate day when the mountains are the main reason for coming.
Getting there from Zurich
The common approach is a train from Zurich to Sargans, then a LIEmobil bus to Vaduz Post. Allow roughly 90 to 120 minutes from Zurich for the whole journey as a planning range, and check the timetable for your date. There is no railway to Vaduz, so the bus is part of the trip. Services also run from Buchs and, across the Austrian border, from Feldkirch. See the LIEmobil timetable for departures.
Tickets and the guest pass
Fares are zone based. A single adult ticket costs CHF 3 in one zone, CHF 4 in two zones and CHF 5 in three or more zones; the matching day tickets are CHF 5, CHF 7 and CHF 9. The CHF 9 network day ticket suits a day with several journeys, such as Vaduz to Malbun and back. Buy from the driver or activate an electronic ticket before boarding. A Swiss Travel Pass is accepted on LIEmobil buses, but check its conditions. Overnight guests can ask their host whether the WELCOME guest pass applies, and should confirm activation and coverage before travelling. See the ticket page and the official guest pass page.
Mountain days
Line 21 continues from Vaduz through Triesenberg to Malbun. Some departures stop at Triesenberg Guferwald, so choose a service that continues to Malbun if that is your destination. Check the weather and the operating status of the Sareis chairlift before an outing, since wind and poor weather can stop it. Carry lunch and water, and note the last bus down.
Rainy days
The Kunstmuseum Liechtenstein opens Tuesday to Sunday and is free on Wednesdays, while the National Museum has its own ticket and closing day. Check opening times before you set out, because Monday closures apply.
