^ What I did was just use a mod that recognizes every single location in the game, even the extremely minor locations where nothing happens. I just roam around and see if I come across a location, eventually I've found everything.

I had a lot of fun with the Solstheim mountain climbing challenge. It consists of four secret mountain peak locations and you need to be on the exact top of it to mark the location, it's a challenge since the top is literally just enough space for you to stand on and you need a horse to be able to get to it.
