1. plane

2. bus

3. ferry to Rijeka or train & then bus

4. ferry to Rijeka or Split & then train

Plane or car. I only travelled by bus once and I would not do it again.

The fastest and easiest way is the plane. Direct flight, 45 min, tickets from around 40€ one way.

I would also recommend a plane 'cause it will take cca 10hours by bus.

Plane is definitely the easiest way. I would not suggest you bus because it take's to much and it's not so cheap. I don't know what your dates are but check the prices on skyscanner for plane, sometimes one way can be around 40-50 euros.

Plane, definitively the best and fastest choice, but should be considered that it happens as it is winter that planes sometimes can't land there - because of severe wind.

BlaBla car.
