What could cause rock formations (small stones, boulders, islands...) to levitate?

You see this in quite a bunch of movies / books (think avatar). What could be a reasoned physical explanation of such phenomenon? Would this explanation impact other things on a planet?

Like most things in nature, I'm assuming it could come from a combination of many factors. Magnetic repel (suggested by @smithkm), hydrogen retaining organisms, high density air, low density rock (like volcanic porous projections)... what else could pitch in so that it would be enough?

Low gravity was suggested but it would imply that air itself would provide less lift to objects, thus not helping with our rocks to fly.
