Recently, this park has received a influx of new features; most importantly, a new visitors center that houses nature exhibits and provides a great lookout over the park. There is on-going construction in the park as they are still working on more upgrades so, if you are going with small children, ensure to inquire and stay away from those spots.
The park has paved trails which can accommodate bikes, but most areas are for those on foot only as to not disturb the wildlife. The area has been known to be home to many small animals such as: frogs, fish, turtles, ducks, rabbits, and plenty of birds. If you are a dog person, there is one trail (Duck Creek Trail) that allows dogs on leashes, otherwise they are prohibited.
More info on the park can be found here. But, all you really need to know is that it's open from dawn till dusk, seven days a week. The visitors center, however, is only from 9 a.m. to 3 p.m. Most importantly, the wetlands are FREE to visit, which is something hard to come by in Vegas. This can be a quick getaway for those tired of the heat, lights and noise of the concrete jungle that is the Vegas Strip. We will be checking it out at the next opportunity and will make sure to share our experience.
