Two days on foot in a country of 2.08 square kilometres, arriving by train from Nice and sleeping either there or in Beausoleil, which is the French street on the other side of the pavement. The first day is the inherited half plus the first reclamation — the Rock, the palace, the museum a prince built into the cliff, and Fontvieille, which was open water until 1966. The second is the harbour, with a breakwater that was cast in Spain and towed here, Monte-Carlo, and six hectares of new country that opened in December 2024.
The Rock, Fontvieille and the cliff above it
The train arrives inside the mountain and you come up into the middle of the country. Monaco-Ville is the promontory, about sixty metres above the sea, and it is the only part of the state that looks its age, because it is the only part nobody has been able to rebuild. The Genoese put a fortress here in 1215; on 8 January 1297 François Grimaldi got in dressed as a Franciscan, which is why two monks carrying swords stand on the coat of arms. The State Apartments open roughly April to October — restoration work in the Hercules Gallery lifted nineteenth-century overpaint off sixteenth-century frescoes nobody knew were underneath. The Carabiniers change guard in the square at 11:55 and it takes about ten minutes. The cathedral was begun in 1875 out of white La Turbie stone and consecrated in 1911; Rainier III and Grace Kelly are in the ambulatory, and the queue moves past them without stopping. The Oceanographic Museum is at the far end: begun in 1899, opened in 1910, a façade that rises straight off the cliff, and Jacques-Yves Cousteau as its director from 1957 to 1988. Fort Antoine at the eastern tip is early eighteenth century and has been an open-air theatre since 1953. Then down the far side into Fontvieille, which was sea until 1966 — the rose garden Rainier III laid out for his wife in 1984, the Prince's car collection, and a football stadium whose pitch sits on a deck above a multi-storey car park. Finish on bus 2 up to the Jardin Exotique, succulents planted on a vertical cliff and opened to the public in 1933, with the Observatory Cave beneath it — a prehistoric cave you can enter only on a guided tour at fixed times, not on your own. Both closed in 2020 for structural work on the cliff and the reopening has run years long, so check the current status before making the trip and keep a fallback for the afternoon if it is still shut.
The harbour, Monte-Carlo and the new six hectares
Start at the covered market on the Place d'Armes, which has traded since 1880 and is the only place in the country where lunch costs what lunch costs. Port Hercule below it is the one deep-water harbour, and the thing to look at is the breakwater: 352 metres of floating concrete, cast in Algeciras in Spain, towed across in 2002 and moored on a single ball joint so that it moves with the swell instead of resisting it. The solar-electric Bateau Bus crosses the harbour in two minutes, counts as a bus line, and costs one bus fare. Up the other side you are on the Grand Prix circuit whether you meant to be or not — Sainte Dévote at the bottom, the climb past Beau Rivage, Massenet, and out into the Place du Casino. The casino has been here since 1863; Charles Garnier added the opera house at the back, inaugurated in January 1879, and Monégasque nationals have never been allowed to gamble in it. There is an entry charge for the gaming rooms, they want a passport at the door, the minimum age is eighteen and the dress code turns away shorts, sportswear and beachwear. Walk east past Villa Sauber, one of the two houses of the Nouveau Musée National, to Larvotto — an artificial beach, rebuilt and reopened in 2021 — and on to Mareterra, six hectares of country that did not exist five years ago, opened in December 2024, with a public promenade around the outside that anyone may walk. Return through the tunnel section of the circuit past the chicane, Tabac and the swimming pool section to Rascasse and Anthony Noghès, the last two corners before the start-finish line, where the barrier sits at the edge of the racing line and the run-off is a kerb.
Good to know
Monaco is not in the European Union but is inside the Schengen area through France, so there is no land border and nothing to show at it — you cross from Beausoleil by walking down a staircase. The practical consequence is that days here count against the same 90-in-180 allowance as France for visa-exempt third-country nationals, and a French Schengen visa admits you. The euro circulates under agreement and Monaco mints its own coins; the country sits inside the EU customs union and VAT area via France, so nothing sold here is duty-free, whatever a shop window says. Cards work everywhere and cash is barely necessary. There is no budget accommodation in the country at all, which is why almost everyone sleeps elsewhere: Beausoleil is literally the next street up and costs a fraction, and Nice is 20–25 minutes by TER with trains until late. Bus 100 along the corniche from Nice is cheaper, slower and much better to look at. Do not drive in — the only parking is paid underground and the one-way system is punitive. Monaco-Monte-Carlo station is buried inside the rock with exits at four different levels, and taking the wrong one costs twenty minutes of climbing; the same problem is solved above ground by a network of several dozen free public lifts, escalators and travelators, marked on the tourist map and running from early morning to around midnight. They are the single most useful thing to know about walking here. EU roaming rules do not apply because Monaco is not in the EU — many operators fold it into their European zone anyway and French networks bleed across the border, but check before arriving rather than after. GHIC and EHIC are likewise not valid, so insurance is necessary: the Princess Grace Hospital in Monaco is a full general hospital and will treat you, and then it will bill you. Swimwear away from the beach, going shirtless and walking barefoot in the street are all against local ordinance and are fined; the country is comprehensively camera-covered and policed at a density nowhere else in Europe matches, which visitors notice mainly as a complete absence of anyone hassling them. The calendar governs prices: the Grand Prix in late May, the Monte-Carlo Masters in April and the Yacht Show in September multiply hotel rates on both sides of the border and impose minimum stays. Building the circuit takes about six weeks and dismantling it about three, so streets begin closing in the second half of April and the barriers are still coming down in June, which makes the fortnight before the race an interesting time to walk the lap and a bad time to be in a hurry. The Palace State Apartments close for the winter, roughly November to March, and cruise calls at Port Hercule can put several thousand people on the Rock between ten and three.
Shorter or longer?
Walk the whole 3.337-kilometre lap corner by corner — Sainte Dévote, Mirabeau, the Fairmont hairpin, the tunnel, the chicane, Tabac, the swimming pool section — and give the afternoon to the second Nouveau Musée National house at Villa Paloma and the Japanese garden at Larvotto. Best in the fortnight before the race, when the grandstands are up and the roads are still open.
The Rock in the morning and Monte-Carlo after lunch, back on an evening train. You keep the palace, the cathedral, the Oceanographic Museum and the casino, and you lose Fontvieille, the Jardin Exotique, the harbour and Mareterra — which is to say you lose the half of the country that was built rather than inherited.
