Prince's Palace of Monaco

Cacti and succulents, some over a century old, on a cliff above the sea, plus a guided trip down about 300 steps into a cave of stalactites.

A small hillside zoo with rescued animals, best when you want animals without committing to a huge zoo day.

Most rooms have terraces over the rose garden or the sea, and the park next door has a playground, a merry-go-round and a pond with turtles and ducks.

Several kinds of sharks in a lagoon tank six meters deep, a coral reef full of color and a rooftop terrace, in a 1910 museum on a cliff above the sea.

About a hundred of the Prince's own cars, among them Monte Carlo Rally cars and Formula 1 cars that raced the Grand Prix.

Some rooms overlook the Grand Prix hairpin, and a kids' club in July and August runs baking and creative workshops.
