In the UK there are 6190 Triangulation (Trig) Points
In the Peak District there are 88, These are those 88.
Several of these are on Private land and inaccessible with out trespassing,
How this is 2023 and we have technology to overcome such things, In this case a DJI Mavic Mini 3 Pro
Trig Point were set up by Ordnance Survey in 1935 onward totaling 6190 around the country, They were used for mapping and elevation etc and from any one trig point you should be able to see at least 2 others, These are now obsolete with modern day GPS and so on but many still remain in place and on prominent hill tops and make for a focal point on hikes and targets to pick up etc
