Liguria, or the Italian Riviera, boasts a bounty of beaches and resort towns, such as tiny Portofino and stylish Rapallo. Hiking trails lead from Portofino to the villages of Cinque Terre. The Riviera of the Setting Sun runs north from Genoa to the French border. Connected by an extensive rail network, most towns are an easy day trip from one another. Genoa is the region's principal city and is home to the famous Cathedral, the Palazzo Reale and an excellent aquarium.
