The highlight of the 200-acre Alabaster Caverns State Park is the cavern formed of alabaster, a rare form of gypsum, making it the largest natural gypsum cave in the world that is open to the public and the only gypsum show cave in the United States. Daily guided tours of Alabaster Cavern leave promptly on the hour from 9am-4pm. For safety reasons, a maximum of 40 visitors are allowed on each tour. A fee is charged for the tour.

The cavern tour includes interpretation by a guide and a well-lit path. Group tour rates are available for school and youth groups only and only after a reservation has been made and a confirmation number been issued. Group reservations are required at least two weeks in advance by calling the park office. NOTE: Tour reservations are recommended during holiday weekends and during local events.

The park also features 11 RV sites, which can be reserved online, and approximately 12 tent sites that are available on a first come, first serve basis. Hiking trails, picnic areas, group shelters with electricity, grills, water and a volleyball court are available at the park. Wild caving is a unique adventure also available at the park.

Wild caving is a sport better known as spelunking. Alabaster Caverns is home to four caves that are kept especially for that particular activity. The caves range in length from 550 feet to 1,600-ft. Permits may be obtained at park office. No permits shall be issued between October 1 and March 31 for protection of hibernating bats. A small fee per person applies. Wild caving is only permitted between the hours of 8am and 3pm. Please contact the park office for an equipment list as well as rules and regulations.

Don't forget to stop by the park's gift shop where you'll find a wide variety of souvenirs including gift items related to nature, the cavern and the resident bat population.
