The easy Hagen Canyon Trail hike takes you through a colorful geographic landscape that was once all underwater. The colorful layers are sediment washed down from the old Sierra Mountains. Over the last 10 million years plate tectonic movement and erosion have formed what you see today. At one point it was a tourist attraction run by the Hagen family, today it’s a state park. The hike is short and shouldn’t take you more than an hour.
