Where is it? Constitution Hill and The Mall, by Buckingham Palace.
What’s quirky about it? Every Sunday, these two grand thoroughfares are closed to traffic. So, if you enjoyed the London Skyride last year, you can recreate it without the 65,000 pesky people on bikes getting in your way, or the marshals telling you not to do whatever you’re doing.
Why bike there? Swan up and down unmolested by traffic to Buckingham Palace, St James’s Park, Wellington Arch, and (most of the way) to Admiralty Arch, Trafalgar Square, Houses of Parliament, etc etc…
