Cactus League Baseball, Ariz.

Every spring, since 1947, Arizona is abuzz as baseball fans flock to catch their favorite teams warm up for the regular season. With 10 facilities hosting 15 teams and more than 200 games each season, the Phoenix metro area is a baseball fan’s dream destination. Under sunny skies, the Arizona Diamondbacks and the Colorado Rockies get in the groove in Scottsdale at Salt River Fields at Talking Stick, where kids are sometimes allowed to run the bases after the game. If you have junior fans in tow, know that many players hang out to sign autographs near foul territory before and after games. Be sure to have a Sharpie pen and some items ready to sign.

Whale shark adventures, Cancun, Mexico

Swimming with the largest fish in the sea is a thrill worth seeking. Whale sharks are massive, reaching lengths of 40 feet and weighing 15 tons. Despite their imposing presence, the gentle creatures peacefully share the warm seas with visitors who arrive via boat from the shores of nearby Cancun. Two at a time, along with a guide, you’ll don a life jacket or wetsuit and fins, before jumping in for a swim with these plankton-slurping vegetarians. No touching is allowed (the mega-fish are considered a “vulnerable species”) but you can swim alongside.

A holiday trip to this Central American outpost offers an extraordinary bounty of experiences packed into a short time frame. This trip offers a chance to explore ancient caves, get immersed in Mayan culture and kayak through freshwater lagoons. You can also snorkel above the second largest barrier reef in the world; hang out with spider monkeys, loggerhead turtles, toucans and kingfishers; and watch the sunset. End your trip at the 25-room, Francis Ford Coppola-owned seaside refuge, where you will fall fast asleep to the sweet song of the natural world in your thatched-roof bungalow.
