This is a nice route, some are path bikes (not presently 12 Oct depicted on google.maps). Some are hike trails. I use my hybrid bike. I think for race bikes is not appropriate unless you walk your bike.
The Columns Dr SE is particularly scenic as you can see very rich house with huge yards. A kind of palaces.
You can think about it as a scenic drive. I like this route very much.
You can visit a few places in
