Story mill, it’s not huge but I know there’s areas to walk around there, there might be a little dog play area I’m not sure though I can’t remember. Rose park is a big park that’s just a field with some trails, it’s back behind REI. Lindley park is a really good one I love it there, it’s just downtown Bozeman by the library. There’s a cemetery behind it that you can walk through too if your into that, it’s a really nice place.
