The Hawaiian island of Maui is a destination for true nature lovers. The ethereal bamboo forest and churning waterfalls in Haleakala National Park can be explored via the Waimoku Falls Trail. Stretch out on warm, golden sands or hit the surf for an unforgettable windsurfing or snorkeling session. Driving the scenic road to Hana along the island’s northeastern shore will be among the most spectacular journeys of your life. Time stands still at the Hawaiian village of Keanae, definitely worth a visit.

Isolated from the rest of Maui by a 52-mile winding drive through coastal rainforest, Hana is an unspoiled beauty dangling from the island's northeastern tip. Untamed Kahanu Garden contains the world's biggest collection of breadfruit and a lava-rock structure believed to be the largest ancient place of worship in Polynesia. Soak up the tropical splendor on beaches with red or black sand. Winter and spring bring humpback whales, visible from Hana Beach County Park.

Whether you’re a high roller or a low-key lounger, Las Vegas has something to suit your vacation taste. Sample fare from top chefs and cornucopian buffets, try your luck at one of the world’s premier casinos, or take in a spectacular show. Just wandering the Strip is enough to get your heart pumping. Once you’ve had enough of the razzle-dazzle, wave hello to the toothy sea life at the Mandalay Bay Shark Reef, hike Red Rock Canyon, or visit the Neon Museum, where old signs take on new life.

Just north of Cancun, this seaside resort community is a far cry from the spring-break crowd. Bordered on one side by the Mexican Caribbean and the other by a wetlands wildlife preserve, the vibe in Playa Mujeres is one of laid-back luxury in a natural, untouched landscape.

The largest of the Galapagos Islands, Isabela is one of the most volcanically active places in the world. Whether this is thrilling or terrifying is up to you.

Walk from Puerto Villamil through mangrove forests and saltwater lagoons to reach the Tortoise Breeding Center. Isabela was once used as an exile for prisoners, who built the devastating Wall of Tears as part of their punishment.
