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.

When people find a great vacation getaway, they keep coming back. This 32-mile-long "Queen of American Lakes" is chock-full of lodging, attractions, eateries and just about any form of recreation you can name. A significant player in American history, Lake George is the site of two great forts, Fort William Henry and Fort Ticonderoga, both open to the public. Before plunging into the myriad activities in this family-friendly town, start off with a relaxing lake cruise to learn about the area. Then, take your pick of recreation: parasailing, fishing, diving, jet skiing, hiking, golfing, minigolf, horseback riding and more. If you've got kids in tow, you can't get away without visiting the Great Escape and Splashwater Kingdom, New York's largest amusement park. Hikers gravitate to the international trail system or Prospect Mountain, which offers panoramic views from the top; for an easier way up, hop on the tram. Among the cleanest and clearest of major U.S. lakes, Lake George is as splendid today as when Thomas Jefferson described it as "...without comparison, the most beautiful water I ever saw."

Ottawa is a compact, clean, cleverly planned centre of culture and politics. And it's an ideal choice for a weekend getaway. Start downtown at the architecturally stunning National Gallery of Canada, and don't miss the Canadian Nature Museum and the National Aviation Museum. Rideau Canal offers boating in the summer and ice-skating in the winter. Gatineau Park attracts cyclists and walkers, while Byward Market blends old and new Ottawa.

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.

Known for its markets and its striking 19th-century limestone architecture, Kingston is a great base for exploring the Thousand Islands and the St. Lawrence River and its national park. Visit Wolfe Island on the free ferry, or hunt for antiques in nearby villages.
