Most of the country is hilly, rugged and rocky, and there are some very fetching sea cliffs. Those keen on wildlife spotting are best advised to visit the Monaco aquarium. The country is almost entirely urban, and not the best spot for nature lovers. With no forest or woodland cover left here, the only fauna you're likely to see are cockroaches, alley cats and other tourists. Monaco's climate is typically Mediterranean, with a bit of rain but not too much chill in the winter.
Summers are dry and can get very hot.
The Monegasque claim they enjoy 300 days of sunshine a year. Car-racing fans will probably want to be here either in January for the Motor Rally, or May for the Grand Prix. There are no border formalities to enter Monaco. No particular risks, but you should consider vaccinations for hepatitis. However, accommodation in this price range is very scarce, and you'll need to book ahead.
