Great Plains State Park is located in southwestern Oklahoma and covers an area of 640 acres. One of the main reasons to visit the park is to experience the natural beauty of the area. With its rolling hills covered in tall grass, the park provides an excellent opportunity for hiking and wildlife viewing. Visitors can also enjoy fishing in the two lakes located within the park, which are stocked with catfish, bass, and crappie.

The park's main attraction is Quartz Mountain, which offers stunning views of the surrounding landscape. A trail leads to the top of the mountain, and visitors can also enjoy rock climbing and rappelling. Another point of interest is the Nature Center, which features exhibits on the area's wildlife and geology.

Interesting facts about the park include its location on the western edge of the Ouachita Mountains and its role as a migration corridor for birds. The area is also home to several rare and endangered species, including the lesser prairie-chicken and the Arkansas River shiner.

The best time of year to visit Great Plains State Park is in the spring and fall when temperatures are mild, and the foliage is at its most colorful. However, the park is open year-round, and each season offers its own unique beauty. Visitors are advised to check the park's website or call ahead to ensure that facilities are open and operational.
