1. Krka National Park
This majestic national park's centrepiece is the Krka River. Its 73 kilometres are lined with gushing, glittering waterfalls. The land surrounding it is an intensely well-nourished green, and the variety of dazzling wild flowers is matched only by that of the birds. You can swim, white-water raft, or just listen to golden eagles squawking overhead as you gaze at the view.
