The popular Musée d'Art Moderne et d'Art Contemporain (Museum of Modern & Contemporary Art, or MAMAC for short) is a fabulous place to beat the heat, especially if you're traveling in the summertime. The museum features a wide array of Nice-based modern artists, most notably Yves Klein. Keep in mind that recent travelers raved more about the building's architecture and panoramic views than the art, and they especially recommend travelers visit the rooftop for a sweeping vista of the city or grab a bite at the museum's restaurant.

The museum, which is open Tuesday through Sunday from 11 a.m. to 6 p.m., costs 10 euros (about $12); guided tours cost extra. The museum is located just north of Old Town (Vieille Ville) and is easily accessible on foot, as well as via bus No. 17. For information on exhibitions, visit the museum's website.
