Macau is a small place, where on a good day you can drive from one end to the other in 30 minutes. This makes walking the ideal way to explore winding city streets, nature trails, and long stretches of beach. Most of Macau's population lives on the peninsula attached to mainland China. The region's most famous sights are here—Senado Square, the Ruins of St. Paul's, A-Ma Temple—as are most of the luxury hotels and casinos. As in the older sections of Hong Kong, cramped older buildings stand comfortably next to gleaming new structures.
