Nature Walks at Anderson Marsh State Historic Park


In 2024, monthly Guided Nature Walks will be held at Anderson Marsh State Historic Park on the second Saturday of each month, except for January, July and December. 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.

The trail system at the park is also open to visitors during daylight hours for outdoor recreation such as hiking and bird watching.



Walks begin at 8:30am. Meet in the parking lot at 8:15am for an opportunity to observe the birds and other wildlife found in the picnic area.The walks take between 1½ and 3 hours, depending on the route taken.  Steady rain will cancel the nature walk
