256km (160 miles) SE of Puerto Vallarta; 267km (167 miles) SW of Guadalajara; 64km (40 miles) SE of Barra de Navidad Manzanillo has long been known as a resort town with wide, curving beaches, legendary sportfishing, and a highly praised diversity of dive sites. Golf is also an attraction here, with two of Mexico's most popular courses in the area. One reason for its popularity could be Manzanillo's enticing tropical geography -- vast groves of tall palms, abundant mango trees, and successive coves graced with smooth sand beaches. To the north, mountains blanketed with palms rise alongside the shoreline. And over it all lies the veneer of perfect weather, with balmy temperatures and year-round sea breezes. Even the approach by plane into Manzanillo showcases the promise -- you fly in over the beach and golf course. Once on the ground, you exit the airport through a palm grove. Manzanillo is a dichotomous place -- it is both Mexico's busiest commercial seaport and a tranquil, traditional town of multicolor houses cascading down the hillsides to meet the central commercial area of simple seafood restaurants, shell shops, and a few salsa clubs. The activity in Manzanillo divides neatly into two zones: the downtown commercial port and the luxury Santiago Peninsula resort zone to the north. The busy harbor and rail connections to Mexico's interior dominate the downtown zone. A visit to the town's waterfront zócalo provides a glimpse into local life. The exclusive Santiago Peninsula, home to the resorts and golf course, separates Manzanillo's two golden sand bays.
