Forest Staley is a tree-filled St Louis County park that offers beautiful bluff-top views into the Meramec valley that compare if not exceed the awesome view at the top of the newly opened Bluff View Trail. The layout of the land offers great potential for a mountain-bike friendly trail. A trail line to the top of the bluff is possible without tracing fall lines or incorporating any overly steep grades.
The thick green lines in the following image outline the park boundaries, and the thin red line depicts a possible trail route. Areas outside the park boundaries fall within the common ground of the Legends subdivision.
Here is a profile view of the trail in a counterclockwise direction:
While the park doesn't have a dedicated parking lot, the park is close to dedicated bike lanes on Legends Parkway that currently connect to nearby parking at Geggie Elementary and extend all the way to Route 66 Park (and the Al Foster Trail and Chubb Trail once Great River Greenways gets to work).
