Stonehenge is over-commercialised and very expensive.
It's an ancient monument, not a theme park. At one point (EDIT: apparently a long time ago, before 1901) it was free and simply there, in the middle of open countryside.
When I first visited (early 90s) it was already a paid-for attraction but was still quite small-scale.
Now it's become a massive closed off area with, if I remember right, a £10+ entrance fee last time I was there (2016).
They should have just left it as stones in the countryside, as it was: similar to how Avebury stone circle is just on public land.
Also visited Land's End in 1995 and even then it seemed over-commercialised. Again, should have just been left as open countryside. Favourite stretch of the Cornish coast (that I've visited) is the part between Padstow and Tintagel.
At the opposite extreme, I visited the stretch of Worcestershire between Malvern and Ludlow in 1998, centred on the Teme Valley. Very beautiful and unspoilt, and even today few know of it, I suspect.
Only problem was that the footpaths were an utter nightmare - no-one seemed to be maintaining them and I was frequently blocked by barbed wire and over-growth. Maybe this has improved since as I do know a lot of effort was spent on fixing rights of way in the Blair years.
Lands End isn’t the southernmost tip of Great Britain, nor is it the westernmost (that honour going to the Point of Ardnamurchan in Scotland).
Incidentally I wonder how much tourism Ardnamurchan gets?
