The streets of ancient Ephesus; natural spa at Pamukkale; lunch in a Turkish pizzeria; cruising the Mediterranean on a traditional Turkish gulet.

We marvel at the fascinating landscape of Cappadocia from high above in a balloon...and from deep below, prowling an underground city where Christians once hid out. We'll join a circumcision party, explore troglodyte ghost towns, shop for sheep at the market, and chat with an imam. Then we enjoy the modern capital, Ankara, and pay our respects to the father of modern Turkey, Atatürk.

Along the Loire River Valley, the beautiful French countryside is studded with evocative châteaux. Home-basing in Amboise, we visit four unique castles: elegant Chenonceau, massive Chambord, stately Cheverny, and fragrant Villandry. Along the way, we tour Leonardo's home, feed hunting dogs, enjoy the local cuisine, and savor a princely garden.

Side-tripping from Paris into the Ile-de-France, we indulge in the world of royal and aristocratic extravagance in the pre-Revolutionary playground of France's elite. We explore Versailles, Europe's palace of palaces; exquisite Vaux le Vicomte; and extravagant Fontainebleau, home to centuries of French rulers. We'll also marvel at the glass and statuary of Chartres cathedral and dine like kings.

We start in Jerusalem, alive with religious tradition and passion — Christian, Muslim, and Jewish. We then visit cosmopolitan Tel Aviv, with its in-love-with-life beaches; ponder the sad fortress of Masada; and join pilgrims at biblical sights around the Sea of Galilee. We'll also pay our respects at the Yad Vashem Holocaust memorial, drop into an Orthodox Jewish neighborhood, and savor the local cuisine.

Palestine is the Muslim and Arab half of the Holy Land. After visiting Jerusalem, we harvest olives near Ramallah, follow pilgrims to the place of Jesus' birth in Bethlehem, approach Abraham's tomb — as both Jews and Muslims do — in Hebron, drop in on friends for dinner, and bob in the Dead Sea. We'll also learn about walls, Israeli settlements, and the challenges facing this region.

In the shadow of Venice, we visit three great cities. Padua is famed for its venerable university, precious Giotto frescoes, and pilgrim-packed Basilica. Verona is a hit with aficionados of Roman ruins and Romeo and Juliet fans. And Ravenna, with its shimmering mosaics, was once the western bastion of the Byzantine Empire. We enliven each stop with a tasty dose of Italian dolce vita.

Europe's best-preserved 17th-century city, Amsterdam is quaint and jarring, traditional and modern. Filled with history and happy-go-lucky, it's a delight to explore. Uniquely entertaining Amsterdam shows us Rembrandts and Van Goghs, more bikes than cars, flirting prostitutes, and pot-filled coffeeshops — all under tall, skinny facades leaning out below quaint church towers.

By train, bike, and boat, we visit the top Dutch sights outside of Amsterdam: from Haarlem to Rotterdam, and from Delft to the Zuiderzee. Along the way, we enjoy charming towns with fragrant cheese markets, soggy polderland, mighty dikes, and windmills both new and old. Rolling through the Netherlands and connecting with its people, you can't help but think, "Everything's so... Dutch!"

The capital of the Czech Republic, Prague is the best-preserved Baroque city in Central Europe. We experience its massive castle, beloved statue-lined bridge, evocative Jewish Quarter, and thrilling 20th-century history while enjoying its infectious love of music and perhaps the best beer in Europe. With a beautifully preserved Old Town, Prague deserves its nickname: the Golden City of a Hundred Spires.

A tumultuous 20th century left Berlin filled with powerful sights — from evocative memorials, to surviving bits of its communist and fascist days, to its glass-domed Reichstag. We enjoy its now-trendy east side, its people-friendly riverfront, and its vibrant social scene. Reunited Berlin — perhaps the fastest changing and most happening city in Europe — is entertaining more visitors than ever.
