The next destination for this day is the National Park Krka. You can reach it on foot and get all the way to the famous waterfalls. You can even take a swim beneath the high waterfall of Skradinski Buk, but be careful where the area just close to it should be clear. Our recommendation is to take a tour of the whole park as it is a full-day adventure. Check the Croatian Tourism info station in Skradin to deduce the best option, but you should definitely take a walk through the cascades of Skradinski Buk as there are hiking trails, check the island of Visovac with the Franciscan monastery and get to Roški Slap waterfall. Above it, you can climb up to 220m along the 517 wooden steps to reach the prehistoric home of the first men, a cave inhabited continuously from 5000 to 1500 BC. Climb down and take a boat excursion through the Krka canyon with wonderful scenery and reach the orthodox monastery just on the verge of a sailable part of the Krka river. After this, we suggest to sail off Skradin to the island of Zlarin or towards the bay of Grebastica on the coast. In either of these places you can spend the night. Zlarin is a beautiful island, not exploited like some of the other, bigger islands in Croatia. Known through history as an "island of corals", still the knowledge and craft of making the jewelry from corals persist in the Zlarin families so make sure to get one of your own. The rest of the day can be spent in Croatian classics: sun, beach, sea and delicious specialties in your belly floating in the domestic wine sorts.
