Nice walks in the city centre

Hi everyone .. as the title suggests I’m looking for nice walks around the city centre.

I don’t often spend time on my own but one of my New Year’s resolutions was to do just that and get out walking myself. However being a female who is quite anxious about being in quiet places I’ve noticed I keep repeating the same walks, aka the botanics, Arthur’s seat, blackford hill..

Does anyone have some suggestions of nice walks that are fairly busy so I don’t feel panicked but something a bit different.

Thanks in advance! :)
