Cottage Grove Ravine Regional Park
Where is Cottage Grove Ravine Regional Park?
This Washington County park is in southern Cottage Grove just off Keats Avenue. Our restoration work here is part of a larger partnership effort with Washington County Parks to protect and preserve a natural green corridor for our waters, our wildlife and public access.
That corridor includes additional natural areas directly south of adjacent to the park, including the 3M Cottage Grove facility along the Mississippi RIver, where FMR has been restoring habitat for over 15 years. FMR’s riverfront restoration work at River Oaks Park is also just a few miles downstream.
The public is welcome to visit Cottage Grove Ravine Regional Park. Daily or annual park passes are required. (See Washington County Parks website for more info.)
Our work here takes place on Dakota homelands. Learn more.
What’s special about Cottage Grove Ravine Regional Park?
Cottage Grove Ravine Regional Park is a beautifully diverse landscape consisting of 515 acres of hills and heavily wooded ravines, a lake and scattered prairie pockets. The park’s varied topography creates a variety of sun exposures and temperature gradients, encouraging diverse plants and habitats. Dozens of wildlife species call the park home, including a number of rare and threatened species.
The park is predominantly a buried glacial tunnel valley formed when melting water flowed under the ice sheet during the Wisconsin Glaciation. The half-mile-wide ravine for which the park is named boasts 80- to 100-foot slopes and runs into Ravine Lake.
A pleasant place to fish, the lake holds walleye and largemouth bass. From its shores, birdwatchers can spot herons, egrets, hawks and eagles. Additionally, Cottage Grove Ravine Regional Park offers hiking trails, paved trails for walking and biking, cross-country ski trails, a pavilion, grills, and a playground area, and a year-round shelter with restrooms, all of which engage a number of park users throughout the year.
The park's dramatic natural features play an important role in water quality, helping to filter pollution from post-rainstorm runoff that would otherwise enter the Mississippi River.
Our work at Cottage Grove Ravine Regional Park
In 2012, Friends of the Mississippi River completed a natural resource management plan for the southern half of the park. Soon after, we began work to restore the park to a more healthy and self-sustaining condition. In 2021, we updated our management plan to include the entirety of the park and direct future restoration.
Historically, the slopes at Cottage Grove Ravine Regional Park were covered by oak savanna, with oak woodland in the sheltered ravines.
However, invasive plant species at the park have outcompeted native plants for nutrients, light and space. Wildlife struggle to adapt to this degraded habitat. We’re removing invasive species of concern including: buckthorn, black locust, garlic mustard, honeysuckle, Kentucky bluegrass, reed canary grass and smooth brome. We’re also restoring some areas to oak savanna and expanding and protecting remnant prairies. Volunteers support the ongoing work at this breathtaking site.
