Podillya is the borderland within the country whose name means 'borderland'. Podillya is the bridge between the stolid, Russia-leaning east and the pro-European south. A swing district politically, topographically it's more predictable: flat and agricultural. The iconic image of bright blue sky over vast wheat field (possibly the inspiration for the colours of the Ukrainian flag) is practically inescapable here. But Podillya is not all farms and flatlands. Castle hunters will find business to attend to in the region's southern half, particularly in the 'rock island' city of Kamyanets-Podilsky. And there are a handful of unusual sites, including a Hitler bunker and a missile museum, scattered about the region for those with time, stamina and patience to explore.
