On a budget, Český Krumlov Day-Trip still earns its price.
~400–800 CZK bus/transfer round trip
Possibly the most photogenic small town in Central Europe — a castle, a river loop, cobbled lanes and a painted tower that look unreal from the overlook. The honest catch: it's a long 2.5–3 hour each-way haul that makes a day-trip rushed, and by midday it's so tour-packed the magic thins. It rewards an overnight far more than a same-day dash.
