FJ "Red" Kane Park is a nice park in South Arlington that has a playground, duck pond, short trail, and picnic area with grills.
There is a nice playground with two sections for different aged children. There is some natural shade on the smaller kid section, but it definitely still gets hot in summer. The ground is mulch, so beware for younger children. There are swings, slides, and climbing structures. There is a picnic area that has grills available for use. There is a restroom a short walk from the playground.
The pond is a feature that kids can enjoy, as well as playing on the playground equipment.
Fountains are turned off in late November/early December and turned back on in late March/early April to prevent serious freeze damage.
