We didn't camp but checked out the camping areas
There is plenty to see and do here on multiple hiking trails. The Summit Trail to the top is a leg-burner at times but well worth the half-mile effort. Take your time to enjoy the views and the rock formation itself and you'll be able to make it.
We also did the Loop Trail, which is about 4.6 miles around the outside of the Granite Dome and it offers various views of the dome from different angles, which was neat to see.
Several other trails offer different experiences, too, but we'll have to check those out another day. This is a park we'll go back to. Note that you need reservations for timed entry and weekends are way busier than weekdays.
There is rustic camping available both near the parking lot and off of the hiking trails. The ones near the parking lot are just in a grassy area off the asphalt, so not peaceful at all. We thought Moss Lake Camping Area would be nice because you're tenting in clear view of the granite dome the whole time. Also nice that all the hike-in camping areas have vault toilets available.
Bring plenty of water because there is little shade anywhere. Do watch for snakes, we had a rattler on the Loop Trail when we went.
Plenty of parking but RVs would have a tough time maneuvering to anything but the half-dozen spots in the RV lot. And note that RVs cannot camp here. It is tent only, even in the parking lot camping area.
Also note the closest gas is about 18 miles away in Fredericksburg, and there is little to no cell service in much of the park (for Verizon and T-Mobile). If you need a strong signal, you'll have to make the climb up Summit Trail!
