Buttermilk Creek Park

Operated by the Fond du Lac Historical Society, the Galloway House and Village is a recreation of a small Wisconsin village of the 1800s. Included are a print shop, a chapel, and a railroad station. The centerpiece of the village is the Edwin Galloway Mansion, home of the Galloway family from 1820 to 1926. The mansion is well restored and staffed with costumed guides. The Blakely Museum is also on the grounds.

The Fairgrounds Aquatic Center is operated by the Fond du Lac Recreation Department, and is just north of the Fond du Lac County Fairgrounds. It features zero depth entry, two tube slides, two drop slides and interactive water play features. Other amenities include a concession stand, a sand play area and bermed grassy areas around the pool for picnics and enjoying the sunshine.

Hiking and bike trails: Just west of Fond du Lac are two state bike and hiking trails. The Wild Goose Trail begins on County Highway VV just west of the Hickory Street roundabout, crosses I-41 on a pedestrian overpass, and goes southwest 34 miles, skirting the northern edge of the Horicon Marsh, and going through Oakfield and Juneau, WI. The Mascoutin Valley State Trail begins on Rolling Meadows Drive, just north of Scott Street, and continues across Eldorado Marsh about 8 miles west to Rosendale.

The Octagon House was built as the residence of Isaac Brown, a trader and carpenter. It was built with nine secret passageways and spaces, including a tunnel to the woodshed. The house was used as a safe house on the Underground Railroad; a small storage space beneath the porch was used to hide runaway slaves. It was the home of Civil War Major Edwin Brown, who was killed at the battle of Antietam in 1862. Some modern visitors report hearing sounds of small children playing and laughing, and feeling cold hands touching them; these are believed to be the spirits of Edwin Brown's children. The house was featured on the History Channel's show Hidden Passages, as "the second-most haunted house in Wisconsin." The house is not open to the public, but may be seen from the exterior.

Built in 1884 to replace the previous cathedral, which had been destroyed by fire, the Cathedral of Saint Paul is the seat of the Episcopal Archdiocese of Fond du Lac, which includes the northeastern third of Wisconsin. The interior of the cathedral features exquisite wood carvings of the Apostles, Saint Paul, and about 25 angels. St. Michael's Chapel contains the sarcophagus of Bishop Charles Grafton, the bishop at the time of the completion of the present building.
