Development in the breathtaking Bahías de Huatulco (Bays of Huatulco) continues to march forward. Four of the nine bays have been developed, but only Bahía Tangolunda, with its golf course and luxury hotels, has the look of a resort.

If you have a car, you can drive to one of several undeveloped bays and play Robinson Crusoe to your heart's content. Boat tours are also a good way to explore. Standard four- to eight-hour trips—depending on how many bays you visit—might include a lunch of freshly caught fish. Fishing, diving, and snorkeling tours visit the beaches and reefs.
