I just returned from my third time camping at Garner State Park. The first two times were on weekends, this time I went Sunday-Tuesday. I definitely recommend camping during the week if possible, as the park is quieter and less populated, but even on the weekends it isn’t overwhelming or crowded feeling, due to how well planned and spaced out the park is designed. If you can reserve a place in time, and are tent camping, I highly recommend the Pecan Grove campsites. They are sandwiched between the frio river and old baldy, and the main highlights of the park are all a short distance. The sites themselves are well spaced out, generally flat, grassy, and shaded by large pecan trees. They are water only, but this is a hurdle easily overcome by battery operated devices and portable chargers, which is what we have used. One warning I would give, the Park is something of a cellular dead spot, though most people get signal at the top of old baldy and some of the other trails at higher elevation. One person in our group was happy to do the half mile hike three times a day for signal! Others that had AT&T or Cricket (I think) had signal even down by the river and campground. There is WiFi available at the visitor center, though it is very slow. Reserve ahead of time, come early, and be ready to be somewhat off grid, and I promise camping at this park will rival some of your favorite spots.
