Sidie Hollow is a beautiful park!  With 521 acres, 74 campsites, 2 picnic shelters, a 38 acre lake, two clear and cold water trout streams, fishing piers, a boat launch, nearly 10 miles of multi-use hiking and mountain bike trails and two playground areas, Sidie Hollow has proven to be a recreation destination for residents and visitors of Vernon County. 

Sidie Hollow County Park originated in the 1960’s when Vernon County acquired land for the purpose of building a large flood retention dam designed to protect downstream farms and properties from the devastating effects of flash flooding in the Bad Axe River Valley.  Once the dam was completed, the county sold the land back to the State of Wisconsin, but retained a permanent recreation easement on the property so that it could be enjoyed as a county park.
