"The park was extremely clean and very spacious and very breath-taking. The views were extremely nice and the people around were extremely respectful of my space. I had a really great time here with my family. I was able to picnic and walk my dogs all around the park. And across the lakes and over the bridge is because the park is so spacious and so nice. I had a great time in the air. Was extremely fresh and I will definitely come back here again even though you have to pay for parking. But that ISO k because parking is extremely cheap. I definitely recommend anyone who is just even passing by 2 just drop by here. Just even for 1 hour or 2 because this is. A great place and a great place to relax and take a breath from all the hard work."

"I truly enjoy visiting William R Mason Regional Park and spending quality time here with my children. It’s always clean, surrounded by lush greenery, and features a beautiful pond where turtles make their home. The park has great playgrounds for kids and offers a wonderful setting for celebrating birthdays. My only small drawback is the $5 entrance fee."

"We absolutely loved this park! We were in the area for a show and stopped here beforehand. It was a beautiful day to walk around, enjoying the lake and nature. Perfect place for taking pictures, having a picnic, playing outdoor games, going for a walk/jog, or just napping in the grass. There are loads of turtle, geese, ducks, and also some frogs. (Please be mindful not to feed them or leave trash, it really isn't good for them.)
There is a small entry fee. The park is wonderfully maintained and we spent a good few hours there, just enjoying the afternoon. I do recommend wearing sunscreen or a hat on sunny days."
