Lisbon, the capital city of Portugal, has become an increasingly popular place to visit in recent years, with a warm Mediterranean climate in spite of its place facing the Atlantic Ocean. Full of bleached white limestone buildings and intimate alleyways, Lisbon's mix of traditional architecture and contemporary culture makes it the perfect place for a family holiday. Things to do in Lisbon: As Portugal's capital, there is a lot to see and do in Lisbon. Even exploring the city centre will take a few days out of a family holiday as there is no real central district, although Praça do Comércio is a good central place to start, in Baxia, or Rossio, the city's main square which has a sort of Trafalgar Square feel to it. Or you might try climbing up the Cristo Rei, a huge statue of Christ with spectacular views across the whole city. The Castelo de São Jorge also offers great views and isn't quite such a steep climb. A short tram ride to the west of Lisbon will also bring you to Belem, where you can explore attractions like the Belem Tower and the Belem Cultural Centre, which features a fantastic art collection including works by Dali, Picasso, Warhol and Magritte. In downtown Lisbon, you'll also want to visit the Gulbenkian, which has to be Portugal's answer to the British Museum full of fascinating cultural artifacts and with some superb gardens in the grounds. It's possible to have a fascinating educational family holiday in Lisbon, and there are also plenty of great beaches to work on your tan.

An exclusive resort town long recognised for attracting royalty, Estoril lies less than 20 miles west of Lisbon and is probably best known for its casino. One of Europe’s largest, it was the inspiration for the first of Ian Fleming’s James Bond books, "Casino Royale." Estoril’s mild winters and warm sunny summers make it a perfect beach town, with one of the nicest, Praia do Tamariz, lying right next to the casino. So famous has Estoril become that the local coast is now called Costa do Estoril.

A coastal town just 20 miles west of Lisbon, Cascais was once a small fishing village, but its idyllic scenery attracted the attention of artists, writers and expelled European nobility in the 20th century. Today, it still attracts high society, but all society comes in force to enjoy the gorgeous beaches and adventure options like sailing and surfing. The Conde de Castro Guimarães Museum, a former palace, is now open to the public and displays an impressive collection of art and artifacts.

Long the home of Portugal’s monarchs, Sintra is a magnificent town of marvelous historic mansions, all set against the backdrop of lush hills. Sintra’s many castles include the Palácio Nacional de Sintra (a main abode of Portuguese royalty until the early 20th century), the hilltop and storybook Palácio da Pena, Quinta de Regaleira (incorporating several architectural styles and with gorgeous surrounding gardens), the Castelo dos Mouros (Moorish Castle), and the Palácio de Monserrate.

The town that gave the country (and port wine) its very name, Porto is Portugal’s second-largest metropolis after Lisbon. Sometimes called Oporto, it's an age-old city that has one foot firmly in the industrial present. The old town, centered at Ribeira, was built on the hills overlooking the Douro River, and today is a UNESCO World Heritage Site. The 14th-century São Francisco church is a main attraction, as are the local port wine cellars, mostly located across the river at Vila Nova de Gaia.

Everyone who visits Paris for the first time probably has the same punchlist of major attractions to hit: The Louvre, Notre Dame, The Eiffel Tower, etc. Just make sure you leave some time to wander the city’s grand boulevards and eat in as many cafes, bistros and brasseries as possible. And don’t forget the shopping—whether your tastes run to Louis Vuitton or Les Puces (the flea market), you can find it here.

From Shoreditch’s swaggering style to Camden’s punky vibe and chic Portobello Road, London is many worlds in one. The city’s energy means that no two days are the same. Explore royal or historic sites, tick off landmarks from your bucket list, eat and drink in exclusive Michelin-starred restaurants, enjoy a pint in a traditional pub, or get lost down winding cobbled streets and see what you stumble across – when it comes to London, the possibilities are endless.

Amsterdam is truly a biker’s city, although pedaling along the labyrinthine streets can get a little chaotic. Stick to walking and you won’t be disappointed. The gentle canals make a perfect backdrop for exploring the Jordaan and Rembrandtplein square. Pop into the Red Light District if you must—if only so you can say you’ve been there. The Anne Frank House is one of the most moving experiences a traveller can have, and the Van Gogh Museum boasts a sensational collection of works.

The first time you go to New York, go ahead and be a sight-seer—everyone should visit the Statue of Liberty, the Met, Times Square, etc. But on a return trip, pick a neighbourhood and go deep. You’ll find hole-in-the-wall bars, great delis, quirky shops… exploring the non-touristy side of New York is an incredibly rewarding experience for a traveller.

If you’re looking for a budget-friendly island holiday, consider the Bay Islands. Each one appeals to different travellers—Roatan’s the most developed (but still not as built-up as, say, St. Thomas), Guanaia’s rustic and Utila’s in between. All three have great dive spots and beaches.
