SLOVENIA4SEASONS

This agency offers a variety of tours in the country and its neighbors, as well as day excursions (Soča Valley, Postojna Cave...). The online selection includes all of Slovenia's must-sees, so you can be sure not to miss a thing and be completely taken care of. They also offer a great introduction to Croatia's finest assets, an excursion to the Plitvice Lakes from Ljubljana. It would be a shame to miss out on a little detour to explore this UNESCO World Heritage site.
