Punta Cana, on the eastern tip of the Dominican Republic, is what Caribbean postcards are made of: twenty-five miles of white sand, swaying coconut trees and more than 35 resorts (which by law cannot be taller than a palm tree). European tourists long ago discovered Punta Cana and Americans are now catching on. At this affordable tropical getaway, most guests choose to stay in all-inclusive resorts. The town itself isn't a tourist draw; the primary purpose of Punta Cana is relaxation by the sea.
