The most beautiful Croatian rivers run through the karstic areas, which means that they abound in limestone barriers and waterfalls, which in turn, due to the abundance of rain and sun, are bordered by lush vegetation. During the dry season the waterfalls retain sufficient water among the limestone barriers to ensure pleasant touring by canoe, kayak, or indeed for diving. Rivers lose neither their clarity nor their green hue except during the heavy spring and autumn rains.

Canoeing on the rivers of Croatia can also provide memorable cultur-a experiences.
 

The monasteries of Visovac, Holy Archangel and Krupo are located timid the green environs of the Rivers Krka and Krupa, while the Rod-man Mills (Radmanove mlinice) on the River Cetina represent an interesting entity of popular architecture, as do the mills on the River Krka.
