Nature Walk

The Guided Walks are led by volunteer State Parks Docents and provide an opportunity to observe wildlife at the park and learn about their natural habitat, as well as to learn about the natural and cultural history and geology of the area.
Tours of the interior of the historic Anderson Ranch House have been temporarily suspended while renovation work proceeds on the building.
