Europe has so many wonderful cities; it can sometimes be overwhelming to choose which ones to visit. To make your choice a bit easier, we've created vacation guides to some of the best vacation spots in four European countries.

London Guides
London is steeped in history and tradition, but at the same time always at the forefront of contemporary fashion and ideas. There are so many wonderful places to visit in London, guides have a hard time narrowing down the best of the best. World-renowned places, such as Westminster Abbey, Buckingham Palace, the Tower of London and Big Ben are all must sees, as is a ride on The London Eye—a giant Ferris wheel that provides stunning views of the River Thames. Take a stroll in Trafalgar Square, shop on Oxford Street and for museum fans, the British Museum and the Science Museum are amongst the best anywhere.

Prague Travel Guides
Six hundred years of architecture unharmed by war or nature make Prague one of the most beautiful cities in Europe, say Prague Travel Guides.Disappearing behind the Iron Curtain for most of the latter part of the 20th century, Prague re-emerged in 1989 and is today one of Europe's most visited attractions. The city is compact and easy to navigate, from the Old Town Square—which is surrounded by examples of beautiful architecture and offers classical concerts and traditional marionette shows, to the two citadels from which the modern-day city has grown. History buffs can explore castles and cathedrals dating back to medieval times, including Prague Castle, the home of Bohemian heirs between the 11th and 17th centuries. In summer, visitors can take advantage of boat rides down the river under the spectacularly adorned Charles Bridge.

Rome Travel Guides
If you want to experience the culture and commerce of the people that dominated the Mediterranean for more than 300 years, head to Rome. Travel guides suggest taking plenty of time to explore this city because the number of sights in Rome is staggering. The Vatican, the symbolic home for the world's Catholics, is where the Pope presides over St. Peter's Basilica; the Roman Colosseum is a time-capsule of Rome's days past, with ruins from several periods of rule. Spectators once watched chariots charge around the ancient Circus Maximus' 2,034-foot track, and gladiators duel to the death. Most of Rome's squares are decorated with at least one fountain, the most recognizable being La Dolce Vita's Trevi Fountain. Rome also has countless museums, palaces, catacombs, churches and unique districts to keep any visitor occupied.

La Rioja, Spain
La Rioja is the smallest of Spain's Autonomous Communities and is located in the northeastern part of the peninsula—the most outstanding wine-growing area in Spain. Haro is the center of Rioja's wine producers, which are among the finest wines in the world. The small, prosperous town also is famous for its wine festival held in late June where everyone squirts red wine over each other. The food in Rioja is also fabulous, especially the "patatas a la Riojana," a spicy potato dish with chorizo sausage and dried peppers. Logroño, a Roman river port and part of the Camino de Santiago (Route of St. James), is today the capital of La Rioja.
