The Train Ride
With Liechtenstein, the beauty of this tiny country starts before you even arrive. The train ride from Switzerland is a tourist attraction in itself and offers stunning scenery along the way. This tiny landlocked country doesn't have it's own airport, which means Zurich is the usual starting point.
Kunstmuseum
Kunstmuseum Liechtenstein is the state owned museum which hosts modern and contemporary art. Worth a look, even if you're not a huge art fan. Some of the rooms seem really empty with small art scattered around, but I guess that's "Art". The entry fee is minimal, and you can't miss the building as it's on the main street in Vaduz. You'll soon realise that there's only one main street in Vaduz, so everything is within close walking distance.
Street Sculptures
You'll notice there's quite a few different art sculptures lining along the streets of Vaduz. Some as random as a pair of high heels, to some more serious. These are all designs of world famous artists. The most iconic is titled "African King" and made by Gunther Stilling, who's a German sculptor famed for heads and masks.
Cathedral of St. Florin
Vaduz Cathedral is a neo-gothic church in the centre of the city, which has held cathedral status since 1997. Entry is free and the building itself boasts impressive architecture inside and out. I wouldn't solely time your visit for this, but The Princely Crypt of the House of Liechtenstein is located next door, but only opens to the public once a year on All Saints Day (1st November).
The Postal Museum
Definitely an unusual and unique museum in Vaduz, is the Postage Stamp Museum. Opened in 1936 and situated in the centre of Vaduz on the main high street. It's a small place, so you might walk straight past without realising. The purpose of the museum is to tell the history of Liechtenstein's postal service, as well as offering an impressive display of stamps past and present. Admission is free of charge, and of course, there's a gift shop selling stamps.
Hiking
Liechtenstein is surrounded by mountains, which means it's perfect for hikes, with plenty of trails available. The local tourism office in the centre of Vaduz can provide a selection of maps for many trails. Obviously season dependent, but green countryside and blue skies, with a mountain backdrop is perfect hiking territory. If you're visiting for longer than a "day trip", then The Liechtenstein Trail leads through all 11 municipalities of the country, past idyllic vineyards, nature reserves, old village centres, many sights and is peppered with magnificent views. Full details of the trail are here.
Alte Rheinbrucke
Around a 15 minute walk from the city centre is an old wooden bridge called 'Alte Rheinbrucke', which serves as an 'unofficial' border between Liechtenstein and Switzerland. It's believed to be the last wooden border bridge of it's kind, and has a cool signpost at the halfway point where you can stand in two countries at one.
Accommodation Advice
So there's not exactly a huge choice of accommodation options due to the compact size of the country. I wanted to be based in Vaduz, so Giessen Hotel & Coffeehouse hit the spot for me. Centrally located, at a good price, and had a nice local feel around the place. The rooms are compact, but have everything you need. The WiFi connection is fine for remote working and the coffee is great.
Food Factor
There's a great local restaurant in Vaduz called Gasthof Au. It's one of the oldest restaurants in the country, with a home-cooked style menu and outdoor seat. It's also within easy walking distance from the centre of Vaduz.
Good Guide
Liechtenstein is such a small country, so a tour guide definitely isn't needed. I found local tourism board very helpful, both in advance via their website, and in-person at their office. Here's their website.
