This park not only has a play structure but also has a paved trail around a lake. You can feed the geese here and enjoy a peaceful afternoon. I've never had the park be too busy and the park itself is just beautiful.
The big problem with this park though is that the parking is almost non-existent and there is a lot of duck/geese poop around. You'll have to watch where your little ones run.
We went to this park with our playgroup, and it is such a neat space. The park surrounds a small lake with paved trails that go all around it. The lake is in a neighborhood, so you don't hear traffic and it is really peaceful. You will get to see Canadian Geese that have decided to hang out here (they are all over Oregon at this point). The lake is really a neat draw too, with a deck area that take you out to the eage and you will see folks fishing here. There is a small playstructure as well for the kids and lots of open space to run and play. There is lots of grass to sit on for picnics or to relax and plenty of shade under the big trees. Makes for a nice afternoon.
