We stayed at Wilderness in October this fall.  The fall colors were just about fully turned and it was just gorgeous.  This park is geared towards the RV camper and they have sites for just about any size rig.  The sites along the lake are geared more toward the sorter rigs.  Ours is a short 5'er and we fit just fine.

The only downside to this trip was the very high lake levels.  On the west side of the park with the more scenic beaches were just not accessible.  Actually, they didn't exist.  The water level completely inundated them.  Even the shore trees were in the water.  That prevented us from hiking where we had hoped to hike.  That really limited us.

The park was clean and the dump station clean and plenty of room  We would camp here again.
