Rising 200 feet above the surrounding landscape, Gibraltar Rock is a flat-topped butte, an outlier of the Magnesian escarpment. With a thin Platteville-Galena dolomite cap over St. Peter sandstone, the butte offers panoramic views of the Wisconsin River Valley and Lake Wisconsin. Soils are thin, glaciated sandy loams. On the south is a sheer rock face overlooking a large leather-leaf bog and scenic valley. A major portion of the site is a dry-mesic forest dominated by red oak and basswood.

Cliff communities are mostly open and harbor several species of ferns, pale corydalis, columbine, and cliff goldenrod. On the bluff top is an area dominated by red cedar with an understory of the dry prairie. Species include big and little blue-stem, side oats grama, prairie drop-seed, blue-eyed grass, bird's foot violet, pasque flower, prairie smoke, lead-plant, bergamot, whorled milkweed, goldenrods, and asters. The site is used by migrating raptors, which catch thermals formed by the warm cliff face. Gibraltar Rock was originally owned by Columbia County, which transferred ownership to the DNR in 2007. It was designated a State Natural Area in 1969.

Very few State Natural Areas have public facilities, but nearly all are open for a variety of recreational activities as indicated below. Generally, there are no picnic areas, restrooms, or other developments. Parking lots or designated parking areas are noted on individual SNA pages and maps. If a developed trail is present, it will normally be noted on the SNA map and/or under the Maps tab. A compass and topographic map or a GPS unit are useful tools for exploring larger, isolated SNAs.

The good majority of SNAs are isolated and have few or no facilities. Some SNAs have vehicle access lanes or parking lots, but their accessibility may vary depending on weather conditions. Parking lots and lanes are not plowed during winter. Hiking trails may be nonexistent or consist of undeveloped footpaths. A GPS unit or compass and a detailed topographic map are useful tools for exploring larger SNAs.

Entrance fees: Except for Parfrey's Glen, the Cambrian Outlook in the Dells of the Wisconsin River, SNAs within State Parks and some within State Forests, all other DNR-owned SNAs do not have any admission fees. For more information, see Wis. Admin. Code NR 45 [exit DNR]. For non-DNR-owned SNAs, we are unaware of any vehicle or admission fees. However, please contact the landowner for more information.

For hunting opportunities, please view the State Parks for hunting and trapping.

Allowable activities: DNR-owned land

The activities listed below are generally allowed on all DNR-owned SNA lands. Exceptions to this list of public uses, such as SNAs closed to hunting, are noted above and posted with signs on the property site.

Prohibited activities: all SNAs

Although a handful of sites allow activities like primitive camping (e.g. Lower Chippewa River on sand bars) or horseback riding (e.g. S. Kettle Moraine), the activities listed below are generally prohibited on DNR-owned SNAs.

  • Camping and campfires
  • Collecting of animals (other than legally harvested species), non-edible fungi, rocks, minerals, fossils, archaeological artifacts, soil, downed wood, or any other natural material, alive or dead.
  • Collecting for scientific research requires a permit issued by the DNR
  • Collecting of plants including seeds, roots or other non-edible parts of herbaceous plants such as wildflowers or grasses
  • Drones: Flying-related activities, including the use of drones, hang-gliders and model airplanes, are prohibited. Permission may be issued by the SNA Program for the use of drones for educational or research purposes
  • Geocaching
  • Horseback riding
  • Rock climbing
  • Vehicles, including bicycles, ATVs, aircraft, and snowmobiles except on trails and roadways designated for their use.

For rules governing state-owned SNAs and other state lands, please consult Chapter NR 45 Wis. Admin. Code [exit DNR].

Driving directions

From the junction of Highways 113 and 60 in Lodi, go north on 113 for 4.1 miles, then west on County Highway V for 1.1 miles, then south on Gibraltar Rock Road for 0.2 miles to a parking area. A segment of the Ice Age National Scenic Trail leads to the top of the bluff. An old access lane, though shorter and steeper, also leads to the summit. 

Note: Rock climbing is prohibited here.

Gibraltar Rock is open daily from 6:00 a.m. to 8:00 p.m.

The DNR's state natural areas program is comprised of lands owned by the state, private conservation organizations, municipalities, other governmental agencies, educational institutions and private individuals. While the majority of SNAs are open to the public, access may vary according to individual ownership policies. Public use restrictions may apply due to public safety, or to protect endangered or threatened species or unique natural features. Lands may be temporarily closed due to specific management activities.

Users are encouraged to contact the landowner for more specific details. The data shown on these maps have been obtained from various sources, and are of varying age, reliability, and resolution. The data may contain errors or omissions and should not be interpreted as a legal representation of legal ownership boundaries. To create your custom map where you can zoom to a specific location, please use the DNR's Mapping Application.
