Edinburgh is traditionally regarded as having 7 hills, it’s apparently based on the fact Rome was built on 7 hills. Edinburgh’s are not very high (highest is 251m) so it’ll be easy enough like most things it’s actually just doing it!

So far have been to the top of 4:
Arthur’s Seat (climbed it Friday past and about a dozen other times)
Calton Hill (last year and handful of other times)
Blackford Hill (few years ago two or three times)
Castle Rock (home to Edinburgh Castle – went as a child)

Still to go to the top of 3 more:
Corstorphine Hill
Craiglockhart Hill (East)
Braid Hill
