Here's what the web site says about the Capital Wheel:
You’ll feel like you’re sitting on top of the world when you experience National Harbor’s most iconic attraction, The Capital Wheel!Jim and I both enjoyed going up in it. But you're a little too far away from Washington to really see much more than the Washington Monument. But still it was fun to go up in.
As you soar 180 feet above the Potomac River waterfront, you will marvel at the incomparable views. Sights visible include the White House and Capitol, the National Mall, Arlington Cemetery, City of Alexandria, Prince George’s County and the lush parklands throughout the DC-Maryland-Virginia region.
Here are a few pictures.
