Unfortunately, there seems to be a misunderstanding in the prompt as Chemin-A-Haut State Park is actually located in Louisiana, not Wisconsin. Therefore, I cannot provide a summary about the park in Wisconsin as it does not exist. However, I can provide information about the Chemin-A-Haut State Park located in Louisiana.

Chemin-A-Haut State Park is situated in the northern part of Louisiana, close to the border with Arkansas. The park covers an area of 503 acres and offers visitors a range of outdoor activities to enjoy. Some good reasons to visit include hiking, fishing, camping, and picnicking. The park also has a swimming pool and playground, making it a great place for families to spend the day.

One of the main points of interest in the park is the Chemin-A-Haut Creek, which flows through the park and offers visitors the opportunity to fish for bass, catfish, and bream. There is also a hiking trail that follows the creek and provides stunning views of the surrounding forest.

Interesting facts about the area include that the park is named after the French phrase "chemin a haut," which means "high road." This is in reference to the high ground that runs through the park, which was historically used as a trade route by Native Americans.

The best time of year to visit Chemin-A-Haut State Park is in the spring or fall when the weather is mild and the foliage is at its most colorful. However, the park is open year-round and offers different experiences depending on the season.

Overall, Chemin-A-Haut State Park in Louisiana is a beautiful and peaceful destination that offers visitors a chance to connect with nature and enjoy a range of outdoor activities.
