Alabaster Caverns State Park
216981 State Hwy 50A, Freedom, OK
Freedom, OK
A three-quarter-mile passage carved through solid gypsum, its walls shot through with veins of pink and white alabaster, in the ranch country of far northwest Oklahoma.
Alabaster Caverns is one of the largest natural gypsum caves in the world that is open to the public, a passage roughly three-quarters of a mile long carved through solid rock. What sets it apart is the stone itself. The walls are gypsum, and shot through them are veins of alabaster in white and rose-pink, along with a rare black variety found in only a handful of places on earth.
The cave formed the way most caves do not. Instead of limestone slowly dissolved by acidic water over eons, this is gypsum, a softer mineral that water cuts through far more quickly, which gives the cavern its smooth, sculpted look. Above ground the park spreads across a landscape of red-walled canyons and shortgrass prairie that feels a long way from anywhere, which is much of its charm.
What Guests Love
- Walking through one of the largest gypsum caves open to the public anywhere
- The bands of pink, white, and rare black alabaster set into the cave walls
- Watching bats stream out of the cave mouth on a summer evening
- The park's wild canyons and the option of guided caving for the more adventurous
Worth Knowing
- The main cavern is seen on a guided walking tour; wear closed shoes with grip because the floor is uneven and can be slick
- The cave stays cool year round, so bring a light layer even in summer
- Wild caving in the park's other passages is by permit and reservation, and gear rules apply to protect the bats
- This is remote country, so fuel up and check conditions before the drive out

Learn about Alabaster Caverns State Park
A cave cut from gypsum and alabaster
Most famous caves in America are limestone, dissolved grain by grain over hundreds of thousands of years. Alabaster Caverns is different. It is carved through gypsum, a soft mineral laid down when ancient seas evaporated and left thick beds of salt and gypsum behind. Water moving underground cut through that soft rock relatively fast, hollowing out the long main passage that visitors walk today.
The alabaster that gives the park its name is a fine-grained, translucent form of gypsum, prized for centuries by sculptors. Here it appears in veins of white and delicate pink, and, unusually, a rare black variety that is found in only a few locations worldwide. Guides point it out along the walls as the tour moves through the cool, dim passage, past chambers with names earned over generations of visits.
Bats, swallows, and cave life
The cave is a haven for bats, several species of them, which roost in the passages and pour out of the cave mouth at dusk in warm months to hunt insects over the canyons. They are a vital part of the local ecosystem, eating vast numbers of insects each night, and the park manages access carefully to protect them and to guard against the fungal disease that has struck bat colonies across the country.
Cliff swallows nest in the canyon walls, and the wet ledges and pools inside the cave shelter their own small, specialized life. Because so much of the cave's living community depends on being left undisturbed, visitors on wild-caving trips follow strict rules on gear and cleaning, and the park closes sensitive areas when the bats need the quiet.
The canyons above the cave
Alabaster Caverns is more than the cave. The park sits amid a set of rugged canyons cut into red and buff rock, laced with short trails that lead past overlooks, box canyons, and the mouths of other, wilder caves. It is prime country for the more adventurous, and by permit the park allows exploration of several undeveloped passages beyond the guided tour.
The land here is dry, open, and quiet, a mix of shortgrass prairie and rocky breaks where the Cimarron River country begins. Hawks ride the thermals overhead, and on a clear night the stars are startling, far from any city glow. It rewards travelers willing to slow down and take in a corner of Oklahoma that few outsiders ever see.
The country around Freedom
The park lies just outside Freedom, a small ranching town that leans hard into its Old West heritage, with wood-front buildings and a rodeo tradition. This is working cattle country, thinly settled, where the road signs count miles between towns rather than blocks.
The salt flats and prairies of far northwest Oklahoma spread out to the east and north, and the Cimarron River winds through the region. It is a landscape of big weather and long views, and travelers who make the drive tend to remember the quiet as much as the cave itself.
