Ferries Information (from Krk Island)

I would like to know if there’s any ferry from the Krk Island to Senj.
I’m planning a trip to the Krk Island in June and from there I’m visiting Senj and the National Park of Plitvice.
Could you be so kind and let me know the easiest way?

Krk Island has Valbiska ferry port from where ferries run to Cres and Rab Island, not to the mainland. Krtk island is connected by bridge to the mainland. So, my suggestion is to take bus from Krk to Rijeka and from there take another bus to Senj.
