We took the Boat Excursion in August across the Novigrad Sea and along the Zrmanja River with a really friendly and nice skipper, Zoran. The the relaxing and sedate excursion lasted from 9.30am until about 4.30 and was superb from start to finish. The boat was pleasant and comfortable one with a canopy for shade and seated about 15 people. After crossing the sea the Zrmanja River is along a narrow and high rocky canyon with fantastic views and scenery. It eventually changes to more green vegetation and is great photo scenery. Zoran stopped three times for swimming and diving from waterfalls and rocks, and once for a coffee/ice cream break in a town along the river. Along the way we were treated to schnapps and fruit (included in the price). Zoran was a great skipper who obviously enjoyed his work and made people very comfortable and relaxed. Take swimwear, swim shoes if you have them, sun cream and a picnic and water. I spent the entire trip in my swim shorts. The older kids will love it (8+ if they swim) as well as adults. I'm 64 but I felt 24 on this trip... swimming, jumping, diving in natural surroundings and crystal clear warm waters and totally relaxed. Thanks again Zoran. Best value for money day ever. I would do it again without hesitation. If your anywhere near Zadar don't miss this. A far more pleasant and enjoyable experience than the Plitvice Lakes with millions of people and queues. Enjoy!
