Prince's Palace, Oceanographic Museum, Casino: discover the 12 must-see attractions in Monaco with insider tips and practical information for 2026.
Spanning just 2 km2, Monaco packs a density of treasures that few destinations can match. From the Prince's Palace perched atop the Rock to the gleaming yachts reflected in Port Hercule, every neighbourhood in the Principality holds striking discoveries. What to see in Monaco on a first visit or a return trip? Here are the 12 must-see attractions, selected by those who experience Monaco every day.
The Rock: the historic heart of the Principality
The Rock of Monaco, rising 60 metres above the Mediterranean, is the historic core of the Principality. Its cobbled lanes lined with houses from the 16th and 18th centuries lead to three major sites that alone justify a full day of sightseeing.
The Prince's Palace and the State Apartments
Official residence of the Grimaldi family since 1297, the Prince's Palace overlooks the harbour and offers one of the most photographed panoramas on the French Riviera. Every day at precisely 11:55 am, the Changing of the Guard draws visitors and onlookers to Palace Square: a timeless ritual rooted in Monaco's military tradition.
The State Apartments reopen on 30 March 2026 and remain accessible until 15 October. The tour takes you through the Hercules Gallery, the Blue Room, the Throne Room and the York Chamber, where each room tells seven centuries of Monegasque history. Admission is €13 for adults and €8 for children aged 6 to 17.
The Cathedral of Our Lady Immaculate
Built in 1875 in a Romanesque-Byzantine style using white stone from La Turbie, the cathedral houses the tombs of Monaco's princes, including those of Rainier III and Grace Kelly. Entry is free. Worth noting: inside, the altarpiece by Louis Bréa (16th century) deserves close attention for its preserved colours and fine detail.
Saint Martin Gardens
Clinging to the southern cliff of the Rock, these gardens offer a shaded walk among maritime pines, agaves and statues. The paths lead to the Oceanographic Museum and reveal breathtaking views of the Mediterranean. Access is free all year round.
The Oceanographic Museum: a scientific gem on the Rock
Inaugurated in 1910 by Prince Albert I, the Oceanographic Museum of Monaco is far more than an aquarium. Its monumental 100-metre-long façade, carved into the cliff face, houses 6,000 marine specimens across 6,500 m2 of exhibition space.
The Shark Lagoon, the centrepiece of the visit, allows you to observe blacktip reef sharks and rays in a 450,000-litre tank. The exhibition "The Sea Turtle Odyssey", partly open-air, traces the journey of sea turtles and raises awareness about ocean conservation.
The museum is open daily from 10 am to 6 pm (until 7 pm from April to September, and 8 pm in July-August). Admission is €22.50 for adults and €14 for ages 4-17. The only closures are on F1 Grand Prix day and 25 December.
♦ Concierge tip
To visit the Oceanographic Museum without the crowds, arrive right at opening time, 10 am on weekdays. Organised groups typically show up after 11 am. Our guests also enjoy an ideal walking route: from Port Palace, take the public lift at the Pêcheurs car park up to the Rock, walk through Saint Martin Gardens and arrive directly at the museum entrance. Allow about 15 minutes for a pleasant stroll.
Monte-Carlo: heritage and art de vivre
The Monte-Carlo district embodies Monaco's glamorous image across the world. But behind the Belle Époque facades lie architectural treasures that many visitors pass through too quickly.
The Casino de Monte-Carlo
A masterpiece by Charles Garnier inaugurated in 1878, the Casino de Monte-Carlo is worth visiting for its architecture as much as its gaming tables. The marble, onyx and fresco-adorned atrium can be explored free of charge in the morning, until 2 pm. After 2 pm, access to the gaming rooms costs €19 (with a €10 voucher redeemable on site).
A detail worth knowing: Monegasque residents are not permitted to enter the gaming rooms. A "smart casual" dress code applies, and shorts and flip-flops will not make it past the door.
The Opéra de Monte-Carlo (Salle Garnier)
Adjacent to the Casino, the Salle Garnier is an intimate jewel of red velvet and gilt. Inaugurated in 1879, this 524-seat hall has hosted premieres by Berlioz, Massenet and Puccini. The opera season runs from November to April, and the Printemps des Arts Festival brings world-class performances to the Principality each year from March to April.
Casino Square and its gardens
Casino Square is a spectacle in itself. The fountains, meticulously maintained flower beds and vintage cars parked in front of the Casino create a scene found nowhere else on the Riviera. From the side terrace, the view sweeps down to the sea and the Larvotto district.
♦ Concierge tip
Casino Square is best seen at two different times: late morning for the architecture bathed in sunlight, and after 8 pm when the facades light up and prestige cars line up at the entrance. When staying at Port Palace, the evening walk from the harbour to the Casino takes about ten minutes and crosses the Carré d'Or, Monaco's most exclusive shopping district.
Port Hercule and La Condamine: the vibrant heart of Monaco
Port Hercule is one of the few natural harbours on the Mediterranean. It is also the neighbourhood where the pulse of Monegasque life beats strongest, between cafés, the market and waterfront promenades facing the yachts.
The harbour promenade
Walking along the quays of Port Hercule is like reviewing some of the world's finest superyachts. The promenade offers a unique perspective with the Rock on one side and the towers of Monte-Carlo on the other. The port takes on a spectacular dimension during the Monaco Yacht Show in September and transforms into an F1 circuit every year in May-June.
It is precisely here, facing the yachts and at the foot of the Rock, that you will find the Port Palace, whose 50 rooms all offer a direct view of this panorama.
La Condamine Market
Housed beneath a renovated 19th-century metal-framed hall, the Condamine Market is where the Monegasques gather. In the morning, stalls sell fruit, vegetables, flowers and local specialities such as socca and barbajuan. At lunchtime, food counters take over with dishes from around the world at prices that are reasonable by Monaco standards.

The Principality boasts a remarkable botanical heritage, spread across several gardens with very different atmospheres.
The Exotic Garden
Perched on the heights of the Moneghetti district, the Exotic Garden is home to one of the world's largest collections of succulent plants. Giant cacti, euphorbias and agaves cascade down a vertiginous cliff, offering an exceptional panorama of Monaco, the harbour and the Italian coastline on clear days.
The site also includes the Observatory Cave, a natural cavity adorned with stalactites and stalagmites, accessible via a 35-minute guided tour. Please note: the garden has undergone renovation works; the botanical centre remains open free of charge from Tuesday to Saturday (8:30 am - 3:30 pm). Check access conditions on the official website before your visit.
The Japanese Garden
Created in 1994 by landscape architect Yasuo Beppu, the Japanese Garden spans 7,000 m2 by the sea, near the Grimaldi Forum. Waterfalls, stone bridges, lanterns and koi carp create an unexpected oasis of serenity in the heart of the city. Admission is free and the garden opens its gates from 9 am.
The Princess Grace Rose Garden
Located in Fontvieille, this rose garden brings together over 8,000 rose bushes of 300 different varieties in a peaceful setting. Created in 1984 in tribute to Princess Grace, it is particularly spectacular from May to June, during peak bloom. Access is free.
How to plan your visit to Monaco?
How much time do you need to visit Monaco?
A single day is enough to cover the highlights: the Rock in the morning, Monte-Carlo in the afternoon, the harbour at sunset. But Monaco truly reveals itself to those who take the time to stay. Two to three nights allow you to explore each neighbourhood at your own pace, enjoy a terrace dinner overlooking the port and discover the best restaurants in the Principality.
How to get around the Principality?
Monaco is easy to explore on foot: 45 minutes is all it takes to walk from the Exotic Garden to the Larvotto. For the hills, a network of free public lifts and escalators connects the different levels of the city. The bus (€2 per ride) covers the entire territory with six lines. To reach Monaco, the SNCF train station is a 5-minute walk from Port Hercule, and Nice airport is accessible in 30 minutes by car or 7 minutes by helicopter.
What is the best season to visit Monaco?
Every season has its strengths. Spring (April-May) offers mild weather and blooming gardens, with the added bonus of unique springtime activities in Monaco. Summer combines beach days and alfresco evenings. Autumn is ideal for sightseeing without the crowds, with the Yacht Show in September. Winter, mild compared to the rest of Europe, charms with its Christmas decorations and the Monte-Carlo Rally in January.
Experience Monaco from Port Palace
Located directly on Port Hercule, facing the Rock and the Prince's Palace, the Port Palace places its guests at the geographical centre of everything there is to see in Monaco. The Prince's Palace is a 15-minute walk away, the Casino 10 minutes, and the Oceanographic Museum 15 minutes.
Guests staying at the hotel benefit from a dedicated concierge service to arrange every detail: restaurant reservations, event tickets, private transfers from Nice airport, or access to bespoke experiences. In the evening, the La Môme restaurant on the 6th floor offers a panoramic view over the harbour to round off the day.
And when the beaches of Monaco are calling, the Larvotto is just a 15-minute walk away. The rooms and suites at Port Palace become a private grandstand during the Grand Prix, as the circuit runs literally past the hotel.

Book your stayFAQ: common questions about visiting Monaco
Can you visit Monaco in one day?
Yes, one day is enough to see the main sights. Start with the Rock and the Prince's Palace in the morning, have lunch at the Condamine Market, and explore Monte-Carlo and the Casino in the afternoon. To fully enjoy the Monegasque atmosphere, however, plan a stay of two to three nights.
Do you need a visa to visit Monaco?
No, Monaco applies the same entry requirements as France. EU and Schengen area nationals only need a valid ID card. Non-EU visitors must present a valid passport and, depending on their nationality, the Schengen visa that allows them to enter France.
How much do the main attractions in Monaco cost?
Several sites are free: the Changing of the Guard, the Cathedral, Saint Martin Gardens, the Japanese Garden and the Rose Garden. The Prince's Palace (State Apartments) costs €13, the Oceanographic Museum €22.50, and access to the Casino gaming rooms €19 (after 2 pm). Monaco remains an accessible destination, even on a budget.
What events should you not miss in Monaco?
The highlights of the year are the Monte-Carlo Rally in January, the Monte-Carlo Masters tennis tournament in April, the F1 Grand Prix in late May-early June, the Monaco Yacht Show in September and the National Day celebrations on 19 November. Each event transforms the Principality and creates a unique atmosphere.
