We stayed at C3 in McClure Point for 3 nights at $40/night. The website was very helpful in choosing a site that had the view we wanted, and to help plan where we'd place the trailer. One interesting thing about the camp is that most of the spots you'd want to place your trailer in are on the "other" side of the electric/water connections (for us, a gazebo was on the "right" side). This was fine, but make sure your hoses/cords are long enough to get around to the other side of your rig.
Most the sites (at least in the C loop) have good shade and views. We were able to park right under a tree to help keep the inside cool. One thing we found was that some of the branches would drag across the roof during the day due to wind, making a slight sound.
The site we were at (and most of them) have a gazebo with a picnic table and a grill, which is great. Some appear to have a fire pit, but burning wood was off-limits at this time of the year.
Most of the activities were at the other site, Lake MacSwain, which is 8 miles down the road near the entrance (yes, it's an 8-mile drive from the gate to McClure Point). There is one dump station and it's there at MacSwain. A bonus here is that there are 2 actual dumping points at the dump station, side-by-side.
There is a small general store at MacSwain where you can buy food and camping items. When we were here, there was a model plane "convention" flying off the lake, which was pretty fun to watch. You can rent small watercraft and paddle/pedal around the lake.
As far as animal friends go, we did see a couple tarantulas (one across the road and one on the way down from the entrance). They're harmless and kinda fun to watch. We also saw a couple deer and select of birds: turkey vultures, bluebirds, acorn woodpeckers, finches, Canadian geese and various ducks.
