I visited on a breezy spring day and traveled the 4 mile loop. It was quite beautiful and easy enough without being boring. Good signage for the most part.
There are actually three loops that are connected together and spurs that go along the canyon rock where the pictographs are. I hike with my dogs and they loved running and playing there. There is a creek that runs through the canyon, but bring water, of course.
Not that far from Springfield where I’m staying on a work contract ... I’m sure I will be back to visit many times.
