of the big ticket or visitor focused stuff, Arthur’s Seat walk/climb, the Botanic Gardens, and tbh I really enjoyed the Camera Obscura even as a full grown adult. Could do tours of the closes and dungeons, never actually have myself but that definitely will be on the unique side at least
infinite good food and drink options if you just want to wander nice bits of a city and indulge, but that might not be where you wanna focus. But if so than any of Stockbridge, Leith Walk, southside/Morningside will do you nicely. Can give personal favs if you think stopping off to eat drink will be priorities
oh no just meant the city as a whole! i somehow have never done Surgeon’s Museum myself after all these years, so that’s something on my own to-do for the next couple dull months
We’ll be in wandering round mode, so I guess looking for some good wandering targets, .and a few coffee/lquick lunch recommendations if there are any obvious ones that might also be on good wandering routes!
another good one is the Water of Leith walk, can take you from the Shore through some leafy cycle paths, can keep going for ages or pop out at my part of town which is full of all the nice coffee shops
Museum of Childhood. if you like weird looking dolls.
Summerhall. Not sure what’s currently being displayed. There was a great extinction rebellion section, but I could have been only for the Fringe.
Edinburgh Zoo. It’s a zoo, but this one is on a hill. Had a panda on loan when I was there. Depends on your ethical feeling about zoo’s I suppose. Wasn’t cheap. Used Tesco clubcard points for cheaper tickets. This was when I could afford to shop in Tesco.
There’s Fortitude coffee which is <1min across the street. Or, 6-7min stroll to Artisan Roast which, few years since I’ve been but I liked an awful lot!
Also all close to Calton Hill which as @guntrip suggests is worth the stroll.
