I have been following this for a couple of years; https://goo.gl/maps/v5n6EJ6MBwXpLN679 It is a list of places to walk, I would suggest reading the reviews and check out the terrain setting in the maps. Everyone else pretty much listed all of these places, but it is all in one link that you can follow if you have a Google Account.
I prefer going to Pony Pasture and walking around Half Moon Beach, quiet area, lots of trees, until the summer when it is warmer, then the road to the west of it along the river is always a beautiful walk with trees every now and then, I used to love it for photography.
