Plitvice Lakes National Park. The lakes are amazing, there are tonnes of different paths you can choose with spectacular waterfalls, caves, scenery and lookouts. The water is crystal clear and a blindingly bright blue colour with tonnes of fish swimming about. It was about a 2 hour bus ride each way to the lakes from Zadar but totally worth it.
Tom and I hiked trail H and some. Smashed out the trail in about 3 hours (1-3 hours under par) so we hiked up another side of the lakes before grabbing a beer laced with wasp venom (a wasp actually just flew into my beer like an idiot).
