Luxury Destinations: Puerto Vallarta offers visitors a broad spectrum of authentic Mexican experiences, with a wide range of spectacular landscapes, fantastic food (and tequila, of course), and the chance to see some of the rarest animals on land and at sea.

As one of the most responsible, ecotourism locations in the world, doing more to protect and conserve its natural landscape than almost any other destination, Puerto Vallarta stands as a leading example for exotic escapes world-wide. From conservation programs for endangered species to organized eco-awareness days, both the local government and community are involved in taking care of one of the most beautiful areas on earth.

The area has made considerable efforts to protect many of the species that call Puerto Vallarta and its surrounding areas home. Puerto Vallarta is the birthplace of the Humpback Whale and every year, from December to April, humpback whales return to the area to breed. Visitors are offered the once in a lifetime chance to see the whales in their natural environment on a whale-watching excursion in the calm waters of the bay.
