The road cuts through the Saint-Gaudens Historical National Park. It was once the home of the celebrated sculptor, Augustus Saint-Gaudens. The grounds are peppered with casts of his most famous works. If you have time during your ride to look around, it is well worth it. Take the Saint-Gaudens Road to the northwest. If you're just riding through, you pass Blow-Me-Down Pond, a beautiful wetland right next to the road.

If you fancy a break in your ride, this little green tract is considered a birding hot spot, no doubt helped along by its proximity to the much larger Henry Laramie Wildlife Management Area. Or you can watch boaters out on the pond.
