Slovenia isn't big at all, but any experienced traveler could use their own map.
You'll be able to travel where others can't, and you'll see quite a few interesting things.
A detailed map of Slovenia will show you where the most beautiful valleys and mountains are, where the best resorts are. Many tourists do not reach little-known villages in the Julian Alps, and this is only because they do not have a map of Slovenia.
Download a map of the country, roads and sights in advance, and Slovenia will reveal its secrets and wonders to you. The best ski centers, cozy restaurants, island-topped medieval roofs and ancient walls of this mountainous country will become much closer.
