Italy -- Enchanting landscapes, delicious cuisine and the promise of "la dolce vita" draw travelers to Italy. Most itineraries spend time in Rome, Venice and Florence, where art treasures abound (tour guests usually bypass long lines at museums and churches to see the works of Michelangelo, Da Vinci and other masters). Spend time at Tuscan vineyards, explore the cliffside towns of the Cinque Terre and examine the well-preserved ruins of Pompeii.

United States -- Take in the geological wonders of the Southwest's national parks or the brilliant foliage of a New England fall. Photograph glaciers in Alaska and palm-fringed beaches in Hawaii. History buffs will look forward to visits to Gettysburg, Philadelphia and Boston, while those who love beautiful old homes and gardens will enjoy Savannah and Charleston. You also can take a cruise along the Mississippi River or its tributaries, or along the Columbia River.

Canada -- Soak up the alpine beauty of Banff and Jasper in the Canadian Rockies; rail trips in this region are especially popular. Explore vibrant cities like beautiful Vancouver or experience the cowboy culture of Alberta. You can observe polar bears near Churchill in Manitoba in October and November or immerse yourself in the seaside settings of Nova Scotia and Prince Edward Island.

Ireland -- Picture-perfect scenes await on our Ireland tours: fishing villages tucked into pretty harbors, roads winding through emerald hills and waves crashing into rocky headlands. Many tours spend time in Dublin, where the city's Georgian squares and Trinity College are popular stops. Gaze at the views along the Ring of Kerry or visit a whiskey distillery and experience a bit of local culture in a neighborhood pub.

Switzerland -- These vacations showcase stunning Alpine scenery, ritzy mountain resorts, famed railways and national favorites like chocolate and cheese fondue. Spend time in St. Moritz, nestled against a beautiful lake, or Zermatt, in the foothills of the Matterhorn. Walk the old quarters of Lucerne or Zurich, or tour Chillon Castle on Lake Geneva. You might ride the Glacier Express over hundreds of bridges or the Jungfrau Train to Europe's highest railway station.

Scotland -- Stand on the banks of Loch Lomond, immortalized in song, or Loch Ness, famed for its "monster." Ride a ferry to the remote Orkney Islands or tour Stirling Castle, where Mary, Queen of Scots was crowned as an infant. The Old Course in St. Andrews is a shrine for golfers. Many summer departures include tickets to the Royal Edinburgh Military Tattoo, a bagpipe-and-drum extravaganza that will be held August 4-26 next year.

England -- Tours of England often include stays in London, where guests see quintessential sights like Big Ben, the Houses of Parliament, Westminster Abbey and Buckingham Palace. Beyond the capital, ponder the mysterious stone circle of Stonehenge, explore ancient Roman ruins and Tudor Row in Chester, spend time in the scenic Lake District or visit Shakespeare's Stratford-upon-Avon.

France - On these itineraries, most of which start or end in Paris, travelers can explore the gardens of Claude Monet's Giverny, captured in many of the artist's paintings, or stand on the beaches of Normandy, where the Allied invasion began on June 6, 1944. Sample wines in the Loire Valley, discover why Lyon is considered to be the country's gastronomic capital or stroll through the Old Town of Nice. We also offer river cruises on the Seine, Saone, Rhone and the waterways of Bordeaux.

Greece -- Brush up on your ancient history at the Parthenon in Athens, in Olympia (where the first Olympic Games were held) and at Mycenae, excavated in the 19th century. The sky-high monasteries of Meteora were erected on natural sandstone pillars, some more than 1,000 feet high. Many itineraries include a cruise to Greek isles like Mykonos and Santorini, where you can relax on the beaches and dine on fresh seafood.

Spain -- Spain tours can highlight the impressive Prado museum in Madrid, the enormous Plaza de Espana in Seville and the beautiful buildings of Barcelona, such as La Sagrada Familia, the extraordinary cathedral designed by Antoni Gaudi. Many itineraries incorporate the 13th-century Alhambra palace complex in Granada. There usually are opportunities to take in a flamenco show and tastings of tapas or Rioja wines.
