Saddleback Mini Park is a great place to hangout with kids. There's a large play structure for the older kids, a smaller play structure for the little guys and some swings. There is a wooded area to explore, a grassy area on which you can relax, and some picnic tables. It's also the location of the Saddleback Trail Head, a lovely, fairly flat trail, great for a stroll. You'll begin your journey at the trailhead.
Congratulations to _Wynn for the FTF!
