Nestled in the fertile Susquehanna Valley, Harrisburg has played a pivotal role in the shaping of American history, both as a major link in rail and water transportation and as the setting of major Civil War battles. Having bounced back from economic distress in the 1980s, the city is now a vibrant hub of family activities, from cruises along the Susquehanna to arcades and athletics on City Island. The annual Pennsylvania Farm Show is the largest indoor agriculture exposition in the U.S.

Pennsylvania Dutch country is a fascinating destination to explore. Visitors will get a glimpse of farm life as it was in the early 1800s. Visit markets and farm stores for homemade shoofly pie and fresh produce, or shop for a handmade quilt. President James Buchanan's elegant home, Wheatland, is no less historic but contrasts sharply to the simpler Pennsylvania Dutch heritage sites in Lancaster. Consider a side trip to nearby Hershey, home of Hershey Park and the Hershey chocolate factory.

From the National Mall’s monuments and memorials to vibrant neighbourhoods filled with character and charm, DC is a world-class destination featuring breathtaking views, award-winning hotels and hundreds of free things to do.

With more surviving 18th century buildings than any other city in the United States, visiting Annapolis is like stepping back in time to the days when the city was a colonial seaport. Known as America’s Sailing Capital, the city is located on the shores of the Chesapeake Bay and is a paradise for water lovers, famous for its crab cakes, lighthouses, and 500 miles of gorgeous shoreline. Tour the campus of the US Naval Academy, or the Maryland State House, the oldest state capitol still in use.

Charming Mackinac Island is a throwback to old-timey seaside leisure, from the candy-colored facades of downtown shops to the impressive (record-breaking, in fact) front porch of the Victorian-era Grand Hotel. Mackinac is world-famous for its homemade fudge, available in every flavor you can imagine. Work off your sugar high with a round of golf, a bike ride along a seaside trail, or exploring the limestone bluffs of Mackinac Island State Park.

Once a modest mining and ranching town, Ketchum is now a bustling resort town that became a popular ski destination with the settlement of nearby Sun Valley. Bald Mountain towers above the city and draws world class skiers every year. The surrounding wilderness provides a beautiful escape for hiking, trail riding, hunting and sports. Ernest Hemingway was known to have fallen in love with the valley and made his final home in Ketchum.

Enchanting Aero is the most charming of all the islands of this dramatic archipelago. Just 14 villages and three towns dot this calm 19-mile-long island, where gentle roads amble by villages, windmills, dolmen, thatched farmhouses and rich green fields. A perfect place for bicycling, this capsule of times gone by offers Viking ruins, market towns, fields of flowers and an almost fairy-tale ambiance. The best beach on this, Denmark's sunniest spot, is Risemark Strand, on the island's southern tip.
