Tunnelville Cliffs features an extensive series of east-facing Cambrian sandstone cliffs that support a noteworthy flora including a state-threatened species. Sullivant's cool wort, bladder fern, swamp saxifrage, prairie alumroot, jewelweed, mosses, and several liverworts are among the other cliff-associated species found here. Situated above the East Branch of the Kickapoo River, the cliffs are shaded by a mixed forest of large white pine, red oak, yellow birch, basswood, sugar maple, paper birch, and ironwood. Black ash and round-leaved dogwood are also present. Herbaceous species include rattlesnake fern, maidenhair fern, false mermaid-weed, round-lobed hepatica, wild geranium, sweet cicely, Canada mayflower, woodland phlox, and black snakeroot. Below the cliff, the Kickapoo curves away to the east and supports a wetland containing alder, skunk cabbage, wood nettle, and sedges. See pages that can be found along the cliff base. Other natural features include ice caves, waterfalls, and a small goat prairie. Tunnelville Cliffs are owned by the Mississippi Valley Conservancy and were designated a State Natural Area in 2006.

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.
