ArcelorMittal Orbit, UK
The ArcelorMittal Orbit might be entirely manmade, but the views from the top are hard to beat. You’ll be able to see 20 miles in each direction over the London skyline before making your descent. Abseiling from the top is a rare event and hasn’t been readily open to the public until just this year, so get in line now to be one of the first to try it out.
