Attractions and tips

During your trip, immerse yourself in history at the British Museum, home to the famed Rosetta Stone. For a glimpse at the crown jewels, head over to the Tower of London. To get up close and personal - or at least as up close as the Royal Guard will allow - swing by Buckingham Palace.

For views that can’t be beat, climb aboard the London Eye, a 400-foot high Ferris wheel that rests on the South Bank.

The West End offers an exceptional taste of London as this part of the city houses many of the best theaters and historical sites. If your budget is a bit tighter, try King’s Cross, which has a grittier feel but is conveniently located on the subway line, affording easy access to the rest of the city.

London’s climate is relatively temperate, with averages hovering between 30 and 80 degrees Fahrenheit. The coldest months are November to March.
