Coastal Omiš is the place to take boat trips into the lower reaches of the Cetina Gorge, where riverside restaurants serve trout and other local delicacies. Travel agents in Omiš also organize rafting trips on the higher, white-water sections of the Cetina. If you have a car, head for the inland town of Zadvarje, where a lookout point above the upper parts of the gorge offers dramatic views of waterfalls.
