Forget dull moments when traveling in Slovenia with kids. Active families can blitz through a host of adrenaline-buzz activities in magical settings, from relaxed Italianate seaside to the Soca Valley, a natural wonderland by the breathtaking Julian Alps. White water raft the emerald Soca River, bike or ride quiet trails, go canyoning or walk gorges, tackle high ropes or paraglide. Wonders extend beneath the earth among Europe's finest caves: think bats, jaw-dropping caverns and dazzling early human history. And what kid doesn't like a castle? Slovenia has dozens – plus a host of historic towns – straight out of fairytales.
