We've stayed at KOA Placerville many times when our friends lived in the area. The last time only about 2 years ago. It is adequate as a KOA. Lots of shade trees, nice pool, restaurants, shopping, and a casino nearby (not walking distance but a short drive). Last time we were there the park needed a little TLC, as the landscape was overgrown and the sites were less than perfect. But it is nice, and the staff is friendly. I would stay there again if I were in the area. It is the closest place I know of to EldoradoHills, just minutes away.
