Thunder Ridge is your standard National forest campground, all sites have a fire pit and picnic table, the CG has vault toilets and trash service available and water is available by a few centrally located spigots.  Facilities are clean.  The sites themselves are nicely spaced apart and it is not too big of a campground.  There is nice trail down to the water or you can take your vehicle a short 3-4 minute drive to Rampart Reservoir.  This is a popular CG, so book early.  It is at the very south end of the Rampart Range Rec area just above woodland park and nearby Manitou Springs and the Pikes Peak Wilderness.  There are lots of activities nearby for all from hiking, fishing, to great mountain towns to visit and the attractions of Manitou and Pikes Peak.
