Parking lot and parking garage around visitor center, stayed the night one night, no issues. Honestly this town really sucks if you are trying to just find a spot for over night camping. Unless you are in the center of town, you probably will have very limited cell signal. And during the day all the parking every where is pretty much taken or limited to only an hour or so. When I was here in Sept 2021 it was always packed everywhere with people UPDATE Officer came knocking, the city has a no overnight camping policy. The nice officer said they used to have signs that said no overnight, but the city took them out for some reason. He also said we could stay the night at the end of the road at these coords 40.375031,-105.500456
