Take the kids back to the days of the skating rink at the Arkansas Skatium. Head out on Friday or Sunday night to hear music hits from when you were young, both nights the DJ spins oldies, disco, 80s and everything in between. Don't worry about buying skates, you can rent a pair there - all you need to bring are your skating skills.
Take a walk, run, or bike ride down the Arkansas River Trail - or at least part of it. The recreation trail stretches over eleven miles but isn't quite finished yet, when completed it will cover a total of 24 miles. If you decide to brave the whole trail, you'll be walking from downtown Little Rock, to Pinnacle Mountain State Park, from North Little Rock to Cook's Landing, and eventually across Murray Lock and Dam to the Presidential Library. That's a lot of ground to cover, be sure to wear some comfy shoes!
