Wander Around Plitvice Lakes
Ticked off in April 2017
What it is
Plitvice Lakes National Park has 16 terraced lakes joined by waterfalls and wooden walkways.
How to do it
It's about two hours from Zagreb or Zadar. Buy tickets online in summer and follow one of the marked walking routes.
Top tip
Arrive at opening time; the walkways get very busy by midday.
My experience
Ticked off, but the full story is still to be written up.
