Summary

The park is known for its stunning natural caverns made of alabaster, a rare form of gypsum. The caverns are the largest natural gypsum caves in the world open to the public, spanning over 3/4-mile in length.

Visitors can explore the caverns on a guided tour, which takes approximately 45 minutes to an hour. The tour includes a walk through several rooms filled with alabaster formations, including stalactites, stalagmites, and columns. The park also offers recreational activities such as camping, hiking, and fishing.

In addition to the caverns, the park is home to a diverse range of wildlife, including bats, snakes, and spiders. Visitors can also spot unique plant species such as cactus and yucca.

One interesting fact about the park is that it was used as a bomb shelter during the Cold War. The caverns' natural insulation and sturdy structure made it an ideal location for emergency personnel to seek refuge in case of a nuclear attack.

The best time to visit Alabaster Caverns State Park is in the spring or fall when temperatures are mild. During the summer, temperatures can reach over 100 degrees Fahrenheit, making the caves uncomfortably hot. The park is open year-round, but the guided tours may have limited availability during the winter months.

Overall, Alabaster Caverns State Park is a unique destination that offers visitors a chance to explore the largest natural gypsum caves in the world. With its recreational activities and diverse wildlife, the park is a great place to visit for those looking for a unique outdoor adventure.
