There's a map of bitcoin ATMs, but I don't know if they are all on it, or if it's up to date. The copyright on the page says 2015 so the machine locations on it must be from this year.

I have yet to see one in the flesh because the nearest to me is a two hour journey away. When I have time I intend to have a day out to try my first ATM.
