hi webmaster! Unfortunately I haven't been to the Plitvice national park - I've only really travelled the coast and Zagreb in Croatia so far. However, it is definitely in my list of top 5 places I want to visit!! Not only is it amazingly beautiful (UNESCO World Heritage Site) but it's also of a modern historical significance due to events during the Croatian war of independence..
I'd love to take a boat on the lake and walk around the whole park to see all the waterfalls and the wildlife too. I think I'd stay with one of the locals (you can rent rooms) or go camping there to get a true feel for the place, rather than stay in a hotel.
Have you been there webmaster? What did you do? Was it as amazing as I'm imagining!
