If you want to visit Monaco, you will find a sovereign state of 2.08 km² (0.8 sq mi), the second smallest in the world after the Vatican, set on the French Riviera between Nice and the Italian border. People come for the Rock and its palace, the Oceanographic Museum, the Monte-Carlo Casino and the Grand Prix circuit laid out through the streets. This guide brings together what you need to know: entry requirements for US and UK citizens, the climate according to Météo-France normals, access and districts.
The principality has a couple of surprising features. It uses the euro and French is its official language, but it is not part of the European Union. There is no border post with France: in practice you enter it as you would pass from one town to the next; according to GOV.UK, France handles immigration matters for Monaco. Another small European state, the grand duchy, is covered in our Luxembourg guide. On the French side, east of the principality, see our page on things to do in Menton.

Things to do in Monaco: the highlights
The Rock, Monaco-Ville
The Rock is the historic heart of the principality, a spur jutting out into the sea. It is home to the Prince’s Palace, the Cathedral of Our Lady Immaculate, the government building and old lanes. On the Palace Square, the traditional changing of the Monaco guard takes place every day at 11:55 am, in front of Louis XV-era cannons. Arrive a few minutes early to get a spot.
The Oceanographic Museum
Founded by Prince Albert I and officially inaugurated on 29 March 1910, the Oceanographic Museum is built into the cliff face, 85 metres (279 ft) above the sea. Jacques Cousteau directed it from 1957 to 1988. It combines a public aquarium and scientific collections, including a shark lagoon and conservation work on endangered species (corals, seahorses, clownfish). It is the visit best suited to children.
Monte-Carlo and its casino
The first casino was opened in 1863 by Prince Charles III and François Blanc, founder of the Société des Bains de Mer. The current building was designed in 1879 by Charles Garnier, also the architect of the adjoining Monte-Carlo Opera. The gaming rooms are closed to under-18s, and ID is requested at the entrance. The Casino Square and its gardens are free to visit.
The Grand Prix circuit
The Monaco Grand Prix is run on a street circuit designed in 1929. The first race took place on 14 April 1929, and the event has been part of the Formula 1 World Championship since 1950. Outside race time, the track is made up of streets open to traffic: you can follow on foot the Sainte-Dévote corner, the climb to the casino, the tunnel and the harbour. The dates of each edition are published by the Automobile Club de Monaco; during the Grand Prix, the city is partly closed off by the circuit installations.
Port Hercule and La Condamine
Between the Rock and Monte-Carlo, Port Hercule and the La Condamine district form the lively centre of daily life, with the market and shops. It is the best starting point for walking up to the Rock.
The Exotic Garden and Fontvieille
The Exotic Garden, clinging to the cliff above Fontvieille, displays succulent plants and gives access to the Observatory Cave, where prehistoric remains have been found. Fontvieille, a district reclaimed from the sea from 1965 onwards, is home to the Princess Grace Rose Garden and the heliport.
Larvotto beach
Larvotto is Monaco’s main beach, east of Monte-Carlo. The site has been redeveloped in stages.

Météo-France normals, Monaco station (altitude 131 m / 430 ft): temperatures 1981-2010, precipitation and rainy days (≥ 1 mm) 1983-2010 (climate sheet 99138001). Météo-France does not publish sunshine hours for this station.
Heat: Monaco compared with the rest of southern France
The sea strongly moderates the heat in Monaco. According to Météo-France, the Monaco station has on average only 4.9 days a year at 30 °C (86 °F) or more (1981-2010 normals), concentrated in July (2.4) and August (2.1). In Perpignan, on the Mediterranean coast of south-western France, the same statistic reaches 36.0 days a year (1991-2020 normals). The difference between day and night is also small: 5.3 to 5.8 °C (10 °F) depending on the month, which makes summer nights warm.

By train: the underground Monaco-Monte-Carlo station is served every half hour during the day by regional TER trains to Menton or Ventimiglia to the east, and to Nice, Cannes or Grasse to the west. It is the simplest way to come from Nice. GOV.UK reports thefts on trains to and from Monaco (updated 10 December 2025).
By air: the nearest airport is Nice Côte d’Azur. GOV.UK reports bag thefts at the airport, particularly in the car rental parks while drivers load their cars. A heliport on the Fontvieille breakwater runs shuttles to Nice airport.
By car: parking is in underground car parks. UK drivers need both the 1968 International Driving Permit and their UK licence in the car, and an IDP cannot be bought outside the UK (GOV.UK, updated 10 December 2025). US drivers should check the rules for France and Monaco on travel.state.gov.
On foot: the principality can be crossed on foot, with public lifts and stairs to deal with the slopes.
Where to stay
Hotels in Monaco are few and upmarket, especially around Monte-Carlo. Many travellers stay in Nice or a neighbouring town on the Riviera and come by train for the day. During the Grand Prix and other major events, book very early or stay further away.
Entry requirements for Monaco
US citizens: you may enter France and Monaco for up to 90 days for tourism or business without a visa. The State Department’s page states that a passport with at least six months’ validity is now required to enter most EU countries, including France, and asks you to check your passport’s expiry date carefully (U.S. Department of State, travel.state.gov, last updated August 11, 2025). This is stricter than the usual Schengen rule of three months beyond departure: if in doubt, contact the Embassy of Monaco or the French Embassy before you travel.
UK citizens: Monaco follows Schengen rules and France handles its immigration matters: no visa for up to 90 days in any 180-day period. Your passport must have been issued less than 10 years before the day you arrive and be valid at least 3 months after the day you plan to leave the Schengen area. Make sure your passport is stamped on entry and exit (GOV.UK, updated 10 December 2025).
Health and safety
Health: according to GOV.UK, the GHIC and EHIC are not accepted in Monaco: UK travellers need adequate travel health insurance and funds to cover treatment and repatriation. The State Department describes medical care as comparable to that in the United States. Whatever your nationality, take out travel insurance covering medical costs.
Safety: GOV.UK says street crime is rare, but take sensible precautions with your passport and valuables; the State Department notes that pickpocketing is a significant problem in France, and the same is true for Monaco.
Emergencies: 112 from a mobile or 18 from a landline (ambulance, fire, police), according to GOV.UK; 17 for the police, according to travel.state.gov.
Phone: Monaco is not in the European Union: check with your carrier whether your plan covers the principality before using mobile data.
Common mistakes in Monaco
Coming without ID: it is requested at the casino entrance.
Arriving by car on a Grand Prix day without checking street closures.
Relying on a GHIC or EHIC: GOV.UK states they are not accepted in Monaco.
Forgetting to check your mobile plan, as the principality is outside the European Union.
