Shift your gaze for just a moment from the glittering waters and chances are an almighty mountain will loom into view. The Dinaric Range, which stretches all the way from Italy to Albania, hugs much of the coast. The limestone karst has bequeathed a wonderland of craggy peaks, caverns, river canyons, waterfalls and ridiculously picturesque lakes. Head further inland and things flatten out again into rolling farmland. Active types will find plenty of chances to get among it on the numerous hiking and biking trails, while the more adventurous can have a go at rock climbing, rafting and zip-lining.
