McKinney Falls State Park, Austin

They offer a lot of hiking options, and one of the falls areas allowed swimming. Super fun place to spend a day, even with kids. They also had staff on site checking the cleanliness of the bathrooms during the day, not just after closing(I watched them doing rounds). That was impressive. My only gripe is that they closed their visitor center early. The sign said they were open until 4pm, and I was walking up at about 3:50 and it was already closed down for the day. That was a bummer. But this was otherwise a solid place to visit.

Very cool hiking and outdoor exploration area local to Austin, so isolated that it's hard to believe it's this close to the city. Recommend that you make reservations, otherwise good luck. Plenty of wide open hiking trails and the Onion Creek bed to explore with kids. Even on a weekend morning in the Fall, it was not overcrowded or anything. Nice visitor center with clean bathrooms and friendly staff to chat with. We did not visit the campground area, so this review does not factor that part of the park. Otherwise, super fun place to explore and enjoy the outdoors. Recommended.
