Great concrete skatepark in Portage MI south of Kalamazoo. It's in the park district of Portage and fenced out. The skatepark is community managed and is actively accepting donations to make it bigger and better. Click here to submit a donation.
The skatepark includes a nice set of bowls with a spine transfer to go from one to the other. There are also stairs and ramps that go up and down the skatepark giving the place a nice upward and downward flow.
The skatepark is located in a park district of Portage with a dog park nearby and some sports fields nearby.
