Kettle Moraine Guide
A glacier built a 100-mile playground in Wisconsin’s backyard, and the southern end of it starts about 25 minutes from Lake Geneva. This is the hub. Use it to get oriented, then jump to the Southern Unit, the Northern Unit, the Ice Age Trail, or the Scenic Drive day trip.
What Is the Kettle Moraine?
The Kettle Moraine is a band of glacial hills running across southeastern Wisconsin, formed about 10,000 years ago where two lobes of the last glacier met. It’s known for kettles (depressions left by buried ice), kames (cone-shaped gravel hills), and eskers (winding ridges left by rivers under the ice). Most of it is protected as the Kettle Moraine State Forest, split into a Northern and a Southern Unit plus three smaller units, and laced with hundreds of miles of trail.
Two ice lobes, the Green Bay Lobe and the Lake Michigan Lobe, ground together right here and then melted, dropping the gravel and sand they carried into the hills you hike today. The result is the best glacial landscape in the Midwest, and a lot of it sits within an easy drive of the lake.
You don’t need to understand the geology to enjoy it, but it helps to know the vocabulary, because the landforms are the attractions. You climb the kames for the views. You hike the eskers like the spine of a ridge. You swim in the kettles that filled with water.
The Units, by Drive Time From Lake Geneva
- Kettle Moraine Southern Unit: The closest and the one you’ll use most, roughly 25 to 45 minutes northwest near Whitewater, La Grange, Palmyra, and Eagle. Mountain biking, serious hiking, Ottawa Lake, and the famous trail systems.
- Kettle Moraine Northern Unit: Wilder and bigger, about 90 minutes north near Campbellsport and Dundee. Parnell Tower, Dundee Mountain, and 30,000 acres of forest.
- Lapham Peak Unit: About 45 to 50 minutes near Delafield. The highest point in Waukesha County, a 45-foot tower, and Wisconsin’s best lighted, snowmaking cross-country ski trails.
- Pike Lake Unit: About 1 hour near Hartford. A spring-fed kettle lake, a swimming beach, and Powder Hill, the second-highest point in southeastern Wisconsin.
- Loew Lake Unit: About 1 hour, a quiet day-use unit on the Ice Age Trail with no admission sticker required.
The Ice Age Trail
The Ice Age National Scenic Trail is a 1,200-mile footpath that runs only in Wisconsin, tracing the edge of the last glacier. Some of its best segments cut straight through the Kettle Moraine, including the Whitewater Lake stretch near Lake Geneva.
The trail is free to hike and marked with yellow blazes. You can do a 3-mile taste of it or chase the whole thing if you’re built that way. Full breakdown on our Ice Age Trail guide.
The Scenic Drive
The Kettle Moraine Scenic Drive is a 115-mile route marked by green acorn signs, running from Whitewater Lake in the south to Elkhart Lake in the north through six counties. It’s one of the best fall-color drives in Wisconsin.
Pick it up at the southern end near Whitewater for an easy day trip, or make a weekend of it. Town-by-town stops, food, and timing are on our Scenic Drive day trip guide.
Best Things To Do in the Kettle Moraine
- Mountain biking the John Muir and Emma Carlin trails: The most popular singletrack for hundreds of miles, in the Southern Unit near La Grange.
- Hiking the Ice Age Trail: Glacial ridges and kettles, from short loops to multi-day backpacking with reservable shelters.
- Climbing the observation towers: Parnell Tower (Northern Unit), Lapham Peak, and Powder Hill at Pike Lake, each a payoff view, especially in October.
- Swimming and paddling: Ottawa Lake, Mauthe Lake, Long Lake, Pike Lake, and Whitewater Lake all have beaches and launches.
- Camping: From year-round Ottawa Lake to primitive Whitewater Lake to backpack shelters on the trail.
- Old World Wisconsin and the historic sites: The state’s big outdoor living-history museum sits right on the edge of the Southern Unit in Eagle.
Fall Color
Fall is the headline season here. The oaks, maples, and aspens turn hard from late September through mid-October, and the rolling terrain means you’re always looking across a valley of color rather than down a flat road.
The towers are the move: Parnell Tower in the Northern Unit and Lapham Peak both put you above the canopy. For a drive, the Scenic Drive was built for exactly this. For a hike, the Ice Age Trail segments through the hardwoods are quieter and just as good.
Winter: Cross-Country Skiing and Snowshoeing
When the snow comes, the Kettle Moraine turns into one of the strongest Nordic-ski regions in the state.
- Lapham Peak: 10 miles of groomed trails, including 2.5 miles lit for night skiing, with snowmaking that keeps them open in lean winters. The best XC setup in southern Wisconsin.
- Southern Unit Nordic and McMiller trails: Miles of groomed track near Palmyra, plus a warming shelter.
- Northern Unit Greenbush and Zillmer trails: Machine-groomed loops through hardwood forest.
Snowshoeing is open almost anywhere in the forest as long as you stay off the groomed ski tracks. You need a state trail pass to ski the groomed trails (see fees below). Snowshoers off the ski trails don’t.
Spring and Summer
Spring brings wildflowers, running springs (Paradise Springs and Scuppernong Springs in the Southern Unit are short, easy walks), and the best birding. Summer is for the beaches, the campgrounds, and early-morning rides before the heat. Bring bug spray for the deep woods, and check yourself for ticks after, that’s just Wisconsin.
Getting to the Kettle Moraine From Lake Geneva
- Southern Unit (Whitewater Lake / La Grange): 25 to 30 minutes via WI-59 and US-12.
- Southern Unit HQ (Eagle) and Old World Wisconsin: about 40 minutes.
- Lapham Peak (Delafield): about 45 to 50 minutes.
- Pike Lake (Hartford) and Holy Hill (Hubertus): about 1 hour.
- Northern Unit (Campbellsport / Dundee): about 90 minutes.
- Elkhart Lake (north end of the Scenic Drive): about 1 hour 50 minutes.
Passes and Fees
Most units need a state park vehicle sticker. A few activities need a trail pass. Buy either at a park office or online from the Wisconsin DNR.
- Vehicle admission sticker: $28/year resident, $38/year non-resident, or $8 to $11 daily. Required for the Southern, Northern, Lapham Peak, and Pike Lake units. Not required for Loew Lake.
- State trail pass: $25/year or $5/day, for mountain bikers and horseback riders 16 and up.
- Cross-country ski pass: $25/year or $5/day for groomed ski trails (Lapham Peak, Nordic, Greenbush, Zillmer).
- Hiking the Ice Age Trail: free, though you still need a vehicle sticker to park inside a state forest.
- Camping: roughly $15 to $27 per night plus a reservation fee, booked through the Wisconsin DNR reservation system or 1-888-947-2757.

When is the best time to see fall color in the Kettle Moraine?
Late September through mid-October is the peak. The observation towers at Parnell (Northern Unit) and Lapham Peak, and the 115-mile Scenic Drive, are the best ways to take it in.
Do you need a pass for the Kettle Moraine?
Most units require a Wisconsin state park vehicle sticker ($28/year resident, $38 non-resident, or $8 to $11 daily). Mountain biking and groomed ski trails need a separate trail pass. Hiking the Ice Age Trail is free.
Where can you cross-country ski in the Kettle Moraine?
Lapham Peak has the best setup, with 10 miles of groomed trail including 2.5 lit miles and snowmaking. The Southern Unit Nordic trails near Palmyra and the Northern Unit Greenbush and Zillmer trails are also groomed.
