Visit two of England’s most acclaimed towns on a full-day excursion into the English countryside. First, visit ivy-draped Oxford, home to the oldest university in the English-speaking world. After free time, it’s on to Stratford-upon-Avon, where Shakespeare was born, married, and buried. You’ll also see the English gardens and orchard belonging to his wife at Anne Hathaway's Cottage.

Enjoy an excursion to the grand palace of Versailles, where Louis XIV held court in the most lavish style imaginable. On a tour, stroll through the elegantly landscaped gardens, the historic Hall of Mirrors, and the ornately decorated State Apartments. Note: Versailles is closed on Mondays.

Venture to the roof of the Swiss Alps, atop one of the majestic peaks that tower over charming Lucerne. Take a boat across Lake Lucerne and ride a cog railway to the top of either Mount Pilatus (best known for its steep railway and its iconic craggy summit) or Mount Rigi (beloved for its original mountain railway and its history as a favorite spot of Mark Twain). Enjoy the splendid views of the quaint villages and fields of Switzerland as you trek along the mountain with your group. Note: Warm clothes and appropriate shoes recommended.

Journey to Pisa on this half-day excursion. Enjoy a guided tour of the city’s Field of Miracles, where you can snap a picture of the 12th-century Leaning Tower, aslant ever since the third floor was built. This is where Galileo was said to have developed his laws of gravity. Also visit the adjacent cathedral and baptistery, which contain exquisite marble pulpits carved in the Gothic style.

Gain unparalleled insight into the lives of the ancient Roman elite on this excursion. Buried in volcanic ash in 79 A.D., the former resort town of Pompeii is now fully excavated and, uniquely preserved as it was, one of the world’s richest archaeological sites. After a guided tour, enjoy an included lunch and free time before returning to Rome for dinner. Note: Comfortable shoes are recommended.
