Just to name a few. Sotano de las Golondrinas (Cave of The Swallows), has become the must do base jumping experience, as one descends over 1200 feet to the cave's floor. Michoacan's billions of butterflies, where it takes a few generations of Monarchs to make the 2000 - 3000 mile migration, literally coating the evergreen trees with a pulsing cloak of Monarchs when they arrive in Mexico. Tranquil, crystal clear waters of the Yucatan's Cenotes luring visitors to a hidden paradise. Holbox Island offering Whale Sharks, and unspoiled eco-lodging amongst the thriving wild animal population. The list goes on. You won't forget these experiences.
