Wisconsin State Natural Areas (SNAs)

The State of Wisconsin describes State Natural Areas as "areas that protect outstanding examples of Wisconsin's native landscape of natural communities, significant geological formations and archeological sites." There are currently 693 sites. The state website is:


and visitation guidelines can be found at:


The POI locations in this file are the recommended parking areas for each SNA in most cases which may a parking lot. Some SNAs have several parking areas and I've chosen what may be the primary or central parking area and occasionally alternative areas. For large SNAs, you should check the SNA web page for the area you plan to visit and possibly choose one of the other locations to park. It is strongly advised that before planning a trip to any SNA, that you find the appropriate web page for that SNA and read its description so that you know what to expect. The POI locations may require your GPS to not have unpaved roads listed as a route Avoidance, especially for sites in National Forests. Each SNA can be found through a search by county or by name:

County: https://dnr.wi.gov/topic/Lands/NaturalAreas/county.html

Name search: https://dnr.wi.gov/topic/Lands/NaturalAreas/alpha.html

This POI file includes a few not generally suited for visitation which are asterisked in the County and Name web search and the POI file will not include a parking area. Always park safely, especially for side-of-road parking where the POI location is just approximate. Do not trespass on private land. The POI file will identify each in the following fashion:

County - SNA name - additional information

This file includes additional information, mostly walking directions from the parking area. Garmin automotive devices offer this information for each location but may involve scrolling or other action on the GPS to see these notes. Some notes offer important parking or other information e.g.:

On Reich Drive by gate, park along shoulder of road south of the mailbox. Do not block Reich Drive as farmer uses it to move large equipment


Park on Cty W by cabin at Fire #13124. To reach Hagar Mountain, go north on foot trail that runs along property line from east side of cabin. Do not trespass on private land

although most are along the lines of:

Park on side of road, walk west to lake
