Minmus, the Mün, Gilly, and even - sorta accidentally - Eve. I sent a dual-rover mission to Gilley but after taking so damned long to land on Gilly due to the low gravity, I decided to just dump my second rover in Eve and be done with it. Even without chutes, that darn thick atmosphere slowed it enough to survive a crash landing skycrane-down. The crane stage exploded and tossed the rover off to the side. One wheel got sort of embedded into the Eve surface but even tilted down and stuck in that attitude, I could drive it all around the landing site. All the solar panels ans science instruments survived too, which was pretty amazing.
