Lonjsko Polje, located in the Sava River basin about an hour's drive southeast of Zagreb, constitutes the largest area of preserved wetlands in Croatia. Though it may be somewhat tame by adventurous standards, there are tours of the river and wetland overflows available by boat from the dock at Drenov Bok, or you can just opt to rent a canoe and take the river exploration into your own hands. Should you be more interested in hiking or biking, the park also offers an abundance of trails for actively getting out and experiencing the countryside (check the listed website for info, trail maps, etc.). Cigoc, a small town situated a stone's throw from the Sava on the western side of Lonjsko Polje, may be of particular interest to any traveling bird aficionados due to its extraordinary white stork population. Meanwhile Krapje, where you'll find the field office and education center, is an intriguing community as well, with its preservation of pragmatic, old buildings and a sense of rural serenity you won't quite find in Zagreb. Whatever your preference, this park is an easy option for a day long excursion into scenic central Croatia.
