Colombo is the gateway to Sri Lanka for most travelers—but don’t be tempted to simply pass through this diverse and interesting city. Take a train ride along the coast to Mount Lavinia, a popular beach, or explore the Talangama Wetland, which several TripAdvisor travelers say is the perfect place to take a break from the bustling streets of the city.

You’re on a gorgeous island off the coast of Thailand—it doesn’t get much better than this. Spend the day on a lively, popular beach, or explore the Ang Thong National Marine Park’s secluded lagoons. Looking for romance? Choose a luxurious five-star resort, a simple, secluded bungalow or pretty much anything in between.

Dubai is a destination that mixes modern culture with history, adventure with world-class shopping and entertainment. Catch a show at the Dubai Opera, see downtown from atop the Burj Khalifa and spend an afternoon along Dubai Creek exploring the gold, textile and spice souks. If you’re looking for thrills, you can float above the desert dunes in a hot air balloon, climb aboard a high-speed ride at IMG Worlds of Adventure or skydive over the Palm Jumeirah.

If it's your first time visiting the Amalfi Coast, chances are you'll do a double-take the first time you see a roadside lemon stand. Yes, those are lemons, and yes, they are the size of your head. But despite their freakish appearance, you will grow to love these lemons because the locals use them to produce limoncello. And take it from us, there's nothing like a glass of limoncello as you gaze out at the sea from the balcony of your hotel in Amalfi. It's pretty much perfection.

The Mediterranean's biggest island is separated from the mainland by the Strait of Messina. A mountainous spot, Sicily's coast and its small islands sit at the foot of volcanoes, including Etna, Stromboli and Vulcano. The Greeks, Romans, Normans and Catalans all left their mark on the island in the form of Byzantine palaces, Gothic castles and Baroque flourishes in capital Palermo. Most larger towns offer interesting museums, but Etna and the Hellenic temples in Agrigento offer particularly unique sights.

It’s nicknamed the Eternal City for a reason. In Rome, you can drink from a street fountain fed by an ancient aqueduct. Or see the same profile on a statue in the Capitoline Museum and the guy making your cappuccino. (Which, of course, you know never to order after 11 am.) Rome is also a city of contrasts—what other place on earth could be home to both the Vatican and La Dolce Vita?

Stroll Las Ramblas and enjoy Barcelona's unique blend of Catalan culture, distinctive architecture, lively nightlife and trendy, stylish hotels. You'll find Europe's best-preserved Gothic Quarter here, as well as amazing architectural works by Gaudi. La Sagrada Familia, considered Gaudi's masterpiece, is still under construction (your entrance fee helps to fund the project). Feel like a picnic? Look no further than the rambunctious La Boqueria market, where you can stock up on local delicacies.
