This is an excellent way to see Plitvice exactly as you want ....
If you don’t really like big groups and don’t want to follow guides, you can spend your day in a different way.
You may want to sit in the shade under the tree after a long walk, or have lunch where you choose or something else...and you will have time to do all that :)
The tour takes about 10 hours, including the ride and the time you spend in the National Park Plitvice ( about 6 hours ).
You can see the entire National park in 4 hours and you still have two hours to relax, take some photos and enjoy.
You’ll have to buy your own entrance ticket at Entrance 1. The ticket includes boat and train rides.
