Emergency numbers
From the section “Emergency services in Slovenia” of the UK government's travel advice for Slovenia, written for British travellers. Reproduced without changes to the wording; formatting adapted.
Police: 113
Ambulance, fire and mountain rescue: 112
Local laws and customs
From the section “Laws and cultural differences” of the UK government's travel advice for Slovenia, written for British travellers. Reproduced without changes to the wording; formatting adapted.
Personal ID
Always carry a copy of your passport as a form of ID. You can get a 50 to 200 euro fine if the police ask you for ID and you cannot show it.
Illegal drugs
Illegal drugs, including cannabis, carry severe penalties. You should expect a long jail sentence and heavy fines for possessing, using or smuggling illegal drugs, including when transiting through the airport.
Airports in Slovenia have excellent technology and security for detecting illegal items. This is also used to scan the baggage of transiting passengers.
Road crossing fines
There are heavy fines for not using designated road crossing points (‘jaywalking’). If you cannot pay an on-the-spot fine, the police or authorities can confiscate your documents or assets until you pay.
Tour guides
Tour guides must display a tour guide card to show they are registered with the Slovenian authorities.
Emergency siren tests
The Slovenian authorities test a nationwide emergency siren on the first Saturday of every month at 12pm. If you hear the siren at another time, follow instructions from the authorities.
Travelling with medicines
From the section “Medication” of the UK government's travel advice for Slovenia, written for British travellers. Reproduced without changes to the wording; formatting adapted.
The legal status and regulation of some medicines prescribed or bought in the UK can be different in other countries.
From the section “Extreme weather and natural disasters” of the UK government's travel advice for Slovenia, written for British travellers. Reproduced without changes to the wording; formatting adapted.
All parts of Slovenia can experience sudden, extreme storms. There can be strong winds and rain, snowfall, lightning and powerful hailstorms. Storms can cause landslides and road closures. Check weather and traffic reports before you travel. If you’re caught in a storm, find shelter until the storm passes and follow local advice.
Flooding
Flash floods can be dangerous, happen with little warning and disrupt transport and other networks. Keep a close eye on weather forecasts and follow the advice of local authorities.
Wildfires
During especially hot and dry periods there is a risk of wildfires. It’s illegal to do anything that starts a fire that poses a danger to human life or could cause significant damage.
Earthquakes
Western Slovenia is on an earthquake fault line and is subject to occasional tremors. The US Federal Emergency Management Agency website has advice about what to do before, during and after an earthquake.
What to pack

Visa and entry rules depend on your nationality and change often, so Trip Rulebook does not summarise them. Each government explains the rules for its own citizens. If you travel on another passport, check with the embassy or the official immigration website of Slovenia.
