Europe, for sure! In most European countries, GMOs are banned from being grown, which means anything local is non-GMO. You'll also find tons of organic (called "bio" here) all over the place. In particular, I've had great luck with organic options everywhere from Switzerland to Slovenia to Belgium. There are only a couple European countries that do allow GMOs (Spain is the big one), but for the most part you're in good shape if you are buying local.
