Do something unusual and try your hand at caving - an activity that is off-the-beaten track for most tourists to the city. Located around 30km from the city, Modrič Cave was only discovered late in the last century and access must be made with suitable helmets and overalls carrying a carbide lamp.
The dark caves are other-worldy, with mesmerising stalactites and stalagmites decorating the walls and ceiling. The vast Cerovac Caves are also an easy day trip from Zadar, the largest cave system in all of Croatia. Located in Velebit National Park, the caves are the location of cave bear remains and remnants of ancient human civilisations.
