Can a Norway citizen travel to Liechtenstein?

Liechtenstein has no commercial airport (small size and mountainous terrain). Travellers arrive via Switzerland (Zurich) or Austria and continue overland. Because you enter via Switzerland, the binding entry requirement is Switzerland's (Schengen Area) — reflected in the visa verdict below — not Liechtenstein's own, which is an open border with no separate immigration control.

Freedom of movement under the EEA Agreement — no visa, no border permit required for entry to Liechtenstein. You may live, work, and study indefinitely under treaty rights.

You're travelling to Switzerland (CH). Your home cellular plan may or may not include data abroad — check your carrier's international options before you fly. An eSIM is a low-commitment alternative if your plan doesn't cover the destination or charges high roaming rates.

Your NO citizenship gives you freedom of movement to this destination under the EU-Switzerland Agreement on the Free Movement of Persons (Switzerland is not an EEA member but grants materially equivalent rights). This is more than visa-free entry: you may enter with a valid passport or national ID card, stay without a visa, and take up residence, employment, self-employment, or study with no permit. After three months you register with local authorities if the country requires it: automatic if you're working or self-employed, but if you're economically inactive (retired, studying, or otherwise not working) you must also hold comprehensive sickness insurance and sufficient resources so you don't become a burden on the host state (Directive 2004/38/EC, Article 7). Your spouse/registered partner and dependent family members can accompany or join you, including non-EU/EEA family members (who may need an entry visa but cannot be charged for the residence right itself). No onward or return ticket is required.
