I arrived at around 6:30 PM with no reservation and had no issues. The guy at the front gate was a peach, super kind and helpful. It’s $25 a night for a tent site. He set me up in site 106 which is about 50 feet away from the (very clean) bathrooms/showers and 100 feet from the lake. The crickets SCREAM at night and there’s some noise from the interstate. There’s also a gas station right outside the park entrance. Plenty of other people camping here but everyone is quiet and respectful. I have 4 bars of 5G with ATT. They also spray for mosquitoes so bugs aren’t really an issue.
