Down the Thames
If you want to get a view of some of London’s monuments I’d highly reccommend the Thamesclipper rides. They are faster than some of the cruise ships to get to different parts of the city, but still allow a good view of the sites as you pass by.
St. Paul’s Cathedral and the Millennium Bridge.
There are new skyscrapers emerging all over London. I imagine in ten years time, the London skyline will look quite different.
The wonderful London skyline from the Shard on the left to the Gherkin on the right.
