Ljubljana’s riverfront, the karst landscape around Postojna and Predjama, and Piran’s lanes and seafront make a three-day drive from city to coast. The itinerary explores public streets, viewpoints and heritage settings. Cave tours, castle interiors, horse experiences, tastings, beach visits and guided excursions are optional additions, with separate tickets and current access checks where needed.

Slovenia's Karst & Coast is a 125 km one-way journey (self-drive). It works best as a 3-day trip; the plan below is the 3-day version for June, built from 171 verified places, with planned transit times, opening hours and daylight checked.
