Windsor Heights Dog Park is a bit tricky to get to, but provides space for dogs to run around in.
Altoona Dog Park is a fun park with a playground and several other sport options.
Raccoon River Park/Sprayground/Beach/Dog park is a huge park with lots to offer – the playground has a unique ship shape, sand pit, and several structures. The trail going around the lake is over 3 miles long, and a mix of crushed rock and pavement. There are lots of wildflowers and wildlife to see along the trail, come back and cool off at the swimming beach.
This is a huge park with lots of different offerings. It has a traditional playground, with the Ashley Okland Star playground across the street, which is listed separately on DSMOF. The Dog park and Lilac Arboretum also have their own separate pages. The Children’s Forest sounds really neat, and Ashley Okland has a fun dirt nature trail.
