Located south and east of the Rainbow Flowage, an impounded stretch of the Wisconsin River, Rainbow Wetlands features a large peatland of sedge meadow, shrub swamp, open bog, and muskeg. The northern and eastern portions of the peatland support an extensive open bog of sphagnum, sedges, and ericaceous shrubs. Dominant species include few-seeded sedge, bog goldenrod, bog aster, steeple-bush, and Labrador tea. Toward the interior are leather-leaf, small cranberry, and few-seeded sedge on a dense sphagnum mat.
Low sandy islands support stands of jack pine-dominated forest. As one moves south and west, the nutrient gradient changes, bog ericads are much less dominant, and the site grades to an open meadow with scattered tall shrubs. The sedge meadow is dominated by sedges including American woolly-fruit, beaked, star, and few-seeded sedge, blue-joint grass, and willows including bog, meadow, and balsam willow.
Sphagnum mosses are present but are not associated with the usual bog ericads and insectivores. Representative herbs are swamp loosestrife, bog goldenrod, and northern blue-flag iris. The open meadow is interspersed with shrub-carr, marsh, and small islands of tamarack, white pine, paper birch, red maple, and aspen. Birds include sedge wren, swamp sparrow, song sparrow, common yellowthroat, and Nashville warbler. Rainbow Wetlands is owned by the DNR and was designated a State Natural Area in 2007.
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. For non-DNR-owned SNAs, we are unaware of any vehicle or admission fees. However, please contact the landowner for more information.
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.
- Cross country skiing
- Scientific research (permit required)
- Outdoor education
- Wild edibles (What is this?)
- Pets (Rules)
- Wildlife viewing
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
- 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.

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.
