Soufriere's backdrop of the Pitons, sea and rainforest provides a picture perfect setting for a visit to this laid-back and relatively undeveloped town in the south of St. Lucia. Considering that its name is French for "sulphur," it should be no surprise to discover the wealth of hot springs and mineral baths. Other great spots to visit include Diamond Botanical Gardens, a slew of pretty beaches and the bike trails that wind through sugar plantation Anse Mamin. Rent a car to see the town.

You'll find crashing waves off Cabo's Pacific coast and sheltered, calm water on the Sea of Cortez. Given those options, Cabo has built a rare reputation for both excellent outdoor sports (big-game fishing, diving and kayaking, among others) and pure beach relaxation. Of course, there's also great nightlife. Cabo’s resorts, hotels and inns cater to everyone from honeymooners to families to Hollywood stars seeking a weekend getaway.

Everything about Santa Monica sizzles, from hundreds of funky shops and restaurants to more than three miles of white sandy beach, to the multitude of celebrities zipping into the local airport and out on Montana Avenue. The subject of popular songs, movies and television shows ("Baywatch" was one of many filmed here), the city has a vibe like no other. Hollywood haute couture meets surfer chic meets hippie casual, and somehow it all works. A word of advice: ditch the car and walk everywhere. Santa Monica is small and prides itself on being pedestrian- and environmentally friendly. You won't need wheels at the auto-free Third Street Promenade, a stroller's paradise known for its multitude of cinemas, restaurants and street performers. Or at the famous and historic Santa Monica Pier, home to tempting smells from fast-food stalls and the solar-powered, nine-storey high Ferris wheel that has long been a symbol of the city. If your feet start to fail, hop on the electrically powered Tide Shuttle, a bus service that runs along the beach offering great views plus a ride to the artsy Bergamot Station and the Santa Monica Museum of Art, or your next spirited Santa Monica destination.
