Campgrounds and RV parks near Edgerton, WI

Edgerton sits in south-central Wisconsin between Madison and Janesville, on the north end of Lake Koshkonong, a roughly 10,595-acre reservoir on the Rock River popular for boating, fishing, and watersports. The town anchors a compact cluster of private RV parks, county parks, and state park campsites within a short drive of I-90/39, making it a practical base for RV travelers heading to the Madison lakes region. Most campgrounds fall within about ten miles of downtown Edgerton. Milton KOA Holiday sits just off I-90/39 and offers full-hookup pull-through sites for larger rigs. Lakeland RV Campground and Lakeshore Resort front Lake Koshkonong itself, while Creekview Campground and Hickory Hills Campground sit inland along quieter country roads. Creekview Campground is a smaller RV park near I-90 outside Edgerton with creekside sites, water and electrical hookups, and a dump station. Hickory Hills Campground sits farther out in wooded terrain. Nearby Lake Kegonsa State Park, on the northeast shore of Lake Kegonsa in Dane County, adds a public-land option run by the Wisconsin DNR.

Public campsites at Lake Kegonsa State Park are booked through the Wisconsin DNR reservation system on wisconsin.goingtocamp.com or by calling 1-888-947-2757. The family campground has 96 sites, 29 of them with electrical hookups, and reservations can be made up to 11 months before the planned arrival date. A Wisconsin State Park vehicle admission pass is required in addition to the nightly site fee, and nonresidents pay a per-night surcharge. Private parks each use their own booking channels. Milton KOA Holiday reserves online through the KOA site or app. Lakeland RV Campground, Lakeshore Resort, Creekview Campground, and Hickory Hills Campground take reservations directly through their own websites or by phone. For holiday weekends, book eight to twelve weeks out. Cancellations release inventory regularly, so checking within a week of arrival can turn up last-minute openings.
