Personally, that list does not even come close. Certainly, there are some iconic locations which are justifiably well known. There are, though, many other places in the UK which are just as good and all the better for being less famous. Many of the spots the club recently visited in Norfolk would qualify, for example.
As a personal footnote, I have been to the summit of Snowdon, which is the BBC's top view. It was a beautifully clear and sunny day, yet I failed to see anything. Rather than walk up, I took the train which limits the amount of time available to look around as you have to return on the same train which takes you up there. About 100 yards from the summit, a cloud descended over it which restricted visibility to a few feet. On the way back down, with the train in a similar position as when I had first seen the cloud, it lifted.
It's only 10 minutes from where I now live but I've yet to get up to the viewpoint at the top. I've seen some fabulous sunset photos taken up there.
