More ways to explore the area's outdoor wonders
You step out of Ljubljana into an air that tastes faintly of spruce and cold water, windows of the minivan framing a ribbon of karst plateaus and alpine foothills. The day stretches long: first the green heart of Lake Bled, then the underworld of Postojna Cave, and the cliff-hugging Predjama Castle that looks less built than lodged in stone.
