I don't have access to any hunting and fishing spots I had as a kid. Wish I did.
A few years back I was granted the opportunity to hunt shark's teeth, etc at Devil's backbone which I frequented often 45 yrs ago.

As far as "old places" as in human construction/civilization.
1. Great Wall of China. too many times.
2. Excavation site in Old Vienna from a few thousand years ago.
3. Some castles near Bristol England circa 1000 a.d.
