Vining's Trailer Park is a seasonal park located in the Waterloo Recreation area northeast of Jackson, Michigan. It is on both Big and Little Portage Lake about midway between Grass Lake and Munith.

​

The park was built by Donald  Vining and opened in 1958. It was operated by Don until his passing in late 2000. His son, Stephen Vining, continued to manage the park until the end of the 2016 season.

​

With the start of the 2017 season the park management changed with the sale of the park to Jason Worthing, a life long friend of the family, but it will still maintain all the management values of Don and Steve.
