We can't yet be certain, but the current best guess is that it is predominantly covered with ice. In fact, one of the interesting theories concerning Europa is that the ridges that we can see on the surface were caused by the ice cracking, and the liquid (water?) beneath boiling into space and then refreezing, and then forming pressure ridges when the ice sheets come back together.
The average temperature on the surface of Europa (as in one of Saturn's moons) is around -260 degrees Fahrenheit.
An icy surface.

There is a hidden ocean on Europa as found out by NASA, manifested as churning seas beneath its icy surface.
