Prague has plenty of green space, so slapping a blanket down and snacking on a sandwich shouldn’t be a problem, right? Umm…not exactly. You need to check that it isn’t prohibited to go on the grass, and according to Prague City Hall, if it isn’t forbidden it is permitted. Some tried and tested places include Kampa, which is a central place, and Petřin hill, which affords you great views of the city, though it can get quite busy.
