In my view, the Costa Alegre (also spelled Costalegre) is Mexico's most spectacular coastal area, a 232km (144-mile) stretch that connects tropical forests with a series of dramatic cliff-lined coves and exclusive accommodations. Tiny outpost towns line the coast, while dirt roads trail down to a succession of magical coves with pristine beaches, most of them steeped in privileged exclusivity. The sunset vistas and nighttime stargazing here are incredible -- without any light pollution, it feels like you can reach up and grab the stars. Considered one of Mexico's greatest undiscovered treasures, this coast is becoming a favored hideaway for publicity-fatigued celebrities and those in search of natural seclusion. However, don't be surprised to hear about major development plans for this region as the economy recovers.

The area is referred to as Costa Alegre (Happy Coast) -- the marketer's term -- and Costa Careyes (Turtle Coast), after the many sea turtles that nest here. It is home to an eclectic array of the most captivating and exclusive places to stay in Mexico, with a selective roster of activities that includes championship golf and polo. Along the line, however, you will encounter the funky beach towns that were the original lure for travelers who discovered the area.
