ice itself is an attraction: the rich blue-green sea, diverse shopping, splendid dining and lovely art-deco façades. But there are several spots that a tourist simply must see, such as the Cours Saleya Flower Market, the Matisse Museum, ancient Roman ruins, the Russian Cathedral and more. Nice is second only to Paris in the number of museums and galleries. Be sure you know which spots have the most allure before you visit.
