You can get some help by using gravity assists from Saturnian moons and
you can use some fancy high ISP propulsion (ion drives or what not). But
still we aren't talking about an easy mission here.

Which brings up a interesting possibility; the gravity of the tiny moons
located near and in the rings is very low, and the probe would be
traveling in their orbital plane...so why not land the probe on one of
them and sample its surface?
