The South Kohala coast of the island of Hawaii is home to Waikoloa Beach. Ancient Hawaiian history and culture, including petroglyphs believed to represent the heavens, stands side-by-side with ultra modern full-service resorts. Waikoloa is also home to fine examples of traditional Hawaiian aquaculture. In 1985, the University of Hawaii renovated the Anchialine ponds which today nuture a wide variety of sea life. Nearby Anaeho'omalu Bay has the Ku'uali'i and Kahapapa Fishponds. 

Ecologically diverse and sparsely populated, the Big Island of Hawaii is larger than all the other better-known Hawaiian islands combined. Rental cars allow visitors to discover wonders from snow-capped mountains to rainforests to deserts. Best known for Hawaii Volcanoes National Park, home to the longest volcanic eruption in recorded history, the Big Island caters both to those who crave adventure and to those looking for luxury, with the flotilla of decadent mega-resorts dotted along Kohala Coast.

If watching the sunrise from atop a 10,000-foot volcano, swimming under waterfalls, hiking through craters and luxuriating on white-, red- and even black-sand beaches sounds like paradise, then Maui awaits. Maui is the place to surf and windsurf. Or hop a catamaran to scuba and snorkel on Molokini Island, a crater emerging from the sea that hosts a wealth of marine life. Golf, fine dining, a winery, museums and sipping a mai tai on the beach round out the perfect tropical holiday.

Is there any possible way Las Vegas could not be on our "best nightlife" list? The only way we could possibly omit it is on a technicality—since you can do pretty much anything 24/7 in Vegas, it might be wrong to call it "nightlife."

A charming fishing village, Sayulita is a hidden gem with picturesque beaches, charming restaurants and great food. Unlike some other Mexican towns, tourists mingle with locals in a relaxed atmosphere, without the hustle and bustle of major touristy resorts. For those seeking more nightlife, Puerto Vallarta is a mere 30 minutes away.

With nine bays and 36 beaches, Huatulco is ideal for anyone who loves the sun. It's not an overdeveloped resort town, but the hotels are comfortable—even luxurious. Ecotourism is gaining in popularity, so take a break from sunbathing and try river rafting or a hike through the jungle.

It’s not just for spring-breakers. Cancun, with its golden beaches and perfect climate, is the premiere coastal destination in Mexico. And while there is certainly a 365-day party available for college students, resorts cater well to families and to those seeking solitude. This Yucatan paradise is also the gateway to the ruins of Tulum and Chichén Itzá.

Isla Mujeres offers a wide variety of tempting options for beach lovers, and is a relative bargain. Snorkel with tropical fish amid coral reefs, skim the blue waters by kayak or boat, or windsurf along the shores of soft, sandy beaches. On land, you can sunbathe, dine on seafood, dance to Latin rhythms, tour on a moped or belly up to the bar for fresh, delicious drinks.

A city trapped in time, Havana captures the imagination like no other. Faded glamour meets careful colonial-era reconstruction with a backdrop of irresistible colour. Walk El Malecón, the walkway bordering the ocean; visit Old Havana and the Catedral de San Cristóbal; and listen for salsa music, open-air bazaars and parties that last all night.

Cuba's top beach destination sits on a 13-mile-long peninsula with powder soft sands lapped by waters of the Kawama Channel. Resort hotels teem along the shore that U.S. celebrities and gangsters, including Capone, discovered in the 1920s. Clubs and bars provide mojitos and merriment, after long days baking on the beach, golfing, diving or deep sea fishing. Rent a scooter or hop aboard an open-air tourist train or bus to see more of this stunning spot. Caves, keys and virgin forest add to the area's allure.

We won't lie: Niagara Falls is uber-touristy. There are wax museums and a Ripley's Believe It or Not Museum, and if it's a fast-food chain, you can probably find it here. But even the most jaded hipster shouldn't pass up a chance to visit this town, because the Falls themselves are spectacular.
