Really nice park. Reservations are not slot specific so get there early on busy weekends. Most slots have lots of shade but some can be a bit small. Most pull-through slots did not have much shade. Quite a few slots will require leveling. All of this was fine for us. The paved walking trails provide for a hassle free bike ride or hike. We stayed 4 nights over a Thanksgiving holiday and felt we could have stayed longer.
Truly a wonderful park! Lots of trees makes it a great place for hiking and biking even in a hot Texas summer. We live in North Dallas and have stayed in this park 3 times in the last 6 months. For us, it's a great way to feel like we are out of town without having to make the drive. The biggest downside is limited lakefront access.
