What's the term for something more exotic than just high fantasy?

I like cool vibrant exotic worlds with plenty of different races and cultures. I am talking floating islands, crystal deserts, walking mountains. They are grouped into the category of High Fantasy. But whenever I say High Fantasy, most DMs assume something along the lines of Classic Fantasy. Angry orks, snobby elves, stubborn dwarfs, plain humans. It doesn't 'feel' like High Fantasy, or at least now how I imagined it.

So is there a term to better illustrate my needs?
