Here's info from our site on the closest parking. There's also a map PDF linked on that page.
There is free (2hr) parking under the bridge on South Ave Ext.
Park at the Old Time Warner building, now Spectrum lot. Go all the way back and to the right and there's parking that walks on to the the canal trail 100 yards from the park entrance. Don't park at the Cancer center to the right, their lot is fenced and no direct access to the park.
You'll have to cross the street to get to the park....
