You step into a sun-swept Adriatic morning as your private vehicle slips out of Koper’s sleepy port, the sea close enough to hear its breath. Narrow streets of Piran appear later, their Venetian facades warming in light; inland, a cool hush awaits in Postojna Cave where stone forms keep time in drip and echo.
