Pictured below is Forest Park in St. Louis, Missouri. Quite possibly one of the most beautiful parks I have had the pleasure of visiting. This was part of my bicycle commute for over a year when I lived in St. Louis, Missouri. Even on days I did not commute, Forest park wasn't that far from our home, so I would ride there just for fun.
If you are ever in St. Louis, Missouri, I highly recommend visiting Forest Park. It is well worth your time. In the Fall, this park is breathtakingly beautiful, with fall foliage.
