Depends on how deep you go into the atmosphere, but as you go in, things become brown, ahead of you, all you see is brown, behind you, you see brown, and some stars that fade fast. Eventually, you go in deep enough that all you see is pitch black. At the center, you get to a point where the atmosphere is so thick, it is actually compressed into a liquid. There is no "surface" of Saturn, unless you count that liquid.
