Palisades Kepler State Park is a scenic park situated in Linn County, Arkansas. It covers an area of over 840 acres and offers a range of recreational activities, including hiking, camping, fishing, and boating. The park is known for its breathtaking views of the Cedar River, which flows through the park, and the towering limestone bluffs that surround it.

One of the top points of interest in the park is the 80-foot-tall Palisades-Kepler Observation Tower, which offers panoramic views of the Cedar River valley and the surrounding landscapes. The park also features a picnic area, boat ramp, fishing pier, and over 3 miles of hiking trails that meander through forests and prairies.

Interestingly, the park was named after the German astronomer Johannes Kepler and the palisade-style fortifications used by early settlers in the area. The park is also home to a diverse range of wildlife, including white-tailed deer, wild turkeys, and various species of birds.

The best time to visit Palisades Kepler State Park is during the summer months when the weather is mild and the park is bustling with outdoor activities. However, the park is open year-round, and visitors can enjoy the beautiful fall foliage and winter landscapes as well.
