Super Seven
Monaco Harbour
Likely to be one of the first things you see when you enter Monaco. The harbour is without a doubt the most glamorous in Europe and packed out with super yachts. There's plenty of restaurants and cafes lining the harbour, which will give you panoramic views. In addition, there's an option to take a 2 hour ferry cruise through the harbour and coastline.
Prince's Palace of Monaco
Located high upon the cliff top is the palace which is home to the oldest monarchy in the world.
It's a private residence, so only open to the public at certain times of the year, so check the website beforehand if you want to go inside. In my opinion, even the outside is worth a look. I'd definitely recommend timing your visit with the changing of the guards that takes place at 11:55am daily.
Musee Oceanographique
Regarded as one of the oldest aquariums in the world and has a pretty cool location to go with it. Located 90 metres above the ocean in Le Rocher, which gives a dramatic setting. There's three separate aquariums within the building, but your entrance ticket covers all of them. The breakdown of Tropical Aquarium, Mediterranean Aquarium, and Shark Lagoon means there's something for everyone. There's some rare marine life and a decent restaurant on the roof terrace, which offers a great view of the shoreline.
Les Jardins Saint-Martin
This small botanical garden is located next to the aquarium, so you can definitely tie the two in together. The garden extends around the Le Rocher coastline and has benches where you can sit and relax. It's free entry, so worth a look while you're in the area.
Cathedral
The cathedral is quite modern when compared to others, as it was built between 1875-1884. If you're there on a Sunday from September through to June, it's worth noting that the local choir sing mass at 10am. Free entry and in the same direction as both Les Jardins Saint-Martin and the Aquarium, so tie it all in together.
Japanese Garden
I wasn't expecting to find a beautiful Japanese garden in the French Riviera, but there is one and it's located in the middle of Monte-Carlo. Offering a zen setting in a peaceful atmosphere to switch off from the rest of the city. I was surpised to see so many locals reading books, relaxing with family, and even doing yoga. Monaco alway strikes me as a very fast-paced city, but clearly it has a relaxing side also.
Collection de Voitures Anciennes
This one is for car lovers and offers a chance to view the Prince of Monaco's vintage cars. Located on the Terraces of Fontvieille, which is one of the trendiest neighbourhoods in Monaco. There's almost 100 cars in total, and also 6 historic coaches.
Accommodation Advice
To put it simply, you need to have extremely deep pockets to afford Monaco hotel prices.
A simple solution is to stay in Nice and take one of the regular buses into Monaco. The bus ride itself is stunning, especially sitting on the right side of the bus. In terms of a Nice (the French city) hotel, I stayed at Hotel Univers. It's located in the heart of the city and within easy reach of the Monaco bus stop.
Food Factor
The Starbucks in Monaco is not to be missed. I doubt there's many Starbucks cafes in the world offering views like this one. Located just above the Ni Box and within walking distance to Jardin Japonais. Okay, so the coffee is the same as from any Starbucks, but the outdoor terrace and views are amazing!
Good Guide
You definitely don't need to hire a guide for a tour of Monaco, as it's a micro country, so walking is sufficient. If you're uncomfortable taking a bus by yourself, you can book a Monaco day trip from Nice on viator.com for under 50 Euros a person.
