Not cheap but remember that a day in an attraction park or amusement park is a lot more expensive! The most striking attraction of this unique nature park are the 125 bigger and smaller islands from which many raise as a steep rock from the sea.
The National Park is situated in the central part of the Croation coast between Sibenik and Zadar. From the island Murter (connected with the mainland by bridge) it is about 7 km. by boat and in a daytrip you don't see all islands but the experienced skippers will show you the most beautifull places. You get the opportunity to swim, to drink and eat and to swim and snorkle again.
The diversity of this group of islands is extreme, many of them are covered with trees, others are completedly plain rock, due to the occuring hard wind from the mainland called bura. In combination with the cristal clear sea which allow you to see the bottom as deep as 20 m. or more makes it very much logical that this area was pronounced National Park in the year 1980.
