Pig Alley is one of the most picturesque areas along Duncan Creek Bike Trail. It runs from the north end of North Grove Street, along Duncan Creek, to the brewery. The area acquired its name in the late 1800s when pigs and other livestock owned by the Leinenkugel family roamed there. City residents spent summers swimming or fishing among the rapids in Duncan Creek and winters sledding or skiing on the Leinenkugel's hill, and locals and visitors continue to make fond memories there today.
