Depart by boat to the St Anthony Channel, admiring views of the St Nicholas fortress as you leave the port. In Šibenik, the boat will make a stop to pick up fresh mussels, before passing the Šibenik bridge. Continue along the estuary of the Krka river to Prokljan lake. Arrive in Krka at around 11.30 AM. National Park Krka encompasses 7 beautiful waterfalls and natural pools where you can take a refreshing dip. Beneath the Skradinski Buk waterfall, you can visit a hydroelectric power plant, the second oldest in the world, and the first one in Europe. The park is also home to a few cultural and historical monuments, such as a Franciscan monastery, and several old water mills. You will have plenty of free time to explore the full extent of the park. You can stop at one of the restaurants if you are hungry, or at the souvenir shop to buy some presents to take home. In the mid-afternoon, head back to the boat to start the return journey, returning to Vodice at approximately 5:00 PM.
