Marshall County, Alabama has a cave so big it swallowed three acres of stone forest

It’s 30 minutes from Huntsville

Cathedral Caverns State Park sits on 493 acres in Marshall County, just outside the town of Woodville in northern Alabama.

The whole place is built around a cave system so big the federal government named it a National Natural Landmark back in 1972.

About 60,000 people walk through it every year, and most of them drive over from Huntsville in half an hour. What they find underground takes a lot longer to process than the drive to get there.

A local entrepreneur named it after his wife’s reaction

The cave went by “Bat Cave” for years before a man named Jacob “Jay” Gurley opened it to the public in the 1950s.

His wife took one look at the soaring ceiling and said it looked like a cathedral, so Gurley changed the name.

The limestone that makes up the walls and formations goes back 320 to 350 million years, to the Mississippian geologic period. Native Americans knew about this place long before Gurley did.

Archaeological finds at the entrance date human use back 8,000 years. Alabama bought the cave in 1987 and turned it into a state park by May 2000.

The cave mouth stretches 126 feet across

You can see the entrance from the parking area near the visitor center, and it stops you in your tracks.

The opening runs about 126 feet wide and 25 feet high, making it one of the widest commercial cave entrances in the world. The moment you step inside, the temperature drops to a steady 60 degrees, no matter the season.

That massive gap in the rock used to be the middle of an even larger cave. The other half collapsed a long time ago, leaving this wide-open doorway into the earth.

Paved paths run 1.5 miles through the dark

Guided tours take about 90 minutes and cover roughly 1.5 miles round trip on paved, lit walkways. The paths run about eight feet wide, so you can push a stroller through without any trouble.

If you have mobility needs, the park can arrange golf cart rides with advance notice.

A ranger walks you through the first half, then you head back on your own so you can stop for photos and get a closer look at the formations.

About 11,000 feet of passages have been surveyed in total, but the public trail covers the highlights.

Goliath stands 45 feet tall with a 243-foot base

The biggest thing in the cave is a stalagmite called Goliath, and it earns the name. It rises 45 feet from the cave floor, and its base wraps around to a circumference of 243 feet.

You don’t grasp the size until you walk around it and see it from different angles. Thousands of years of mineral-rich water dripping and depositing calcite, layer by layer, built this thing.

It ranks among the largest stalagmites on the planet.

A 32-foot frozen waterfall lines the cave wall

One of the formations looks exactly like a waterfall that stopped mid-flow. The flowstone stretches 32 feet tall and runs 135 feet long across the cave wall.

Mineral-laden water crept down the rock over centuries and left behind calcite in ripples and ridges.

The cave’s lighting system picks up every fold in the stone, and the effect is so convincing you almost expect it to move. It ranks as one of the largest flowstone formations of its kind.

The Big Room opens to a stone forest beyond

The largest chamber in the cave, called the Big Room, runs 792 feet long and 200 feet wide.

Past it, you walk into a roughly three-acre area packed with stone columns and formations that people call the stalagmite forest. This is where the cathedral name really clicks.

The stone spires rise like columns in a grand hall.

Before you reach the forest, you pass between the Pearly Gates, two tall columns that frame the way in like a doorway.

Shark teeth are still stuck in the ceiling

The Mystery River flows through the cave and can flood passages after a heavy rain, so the state built a bridge to keep the path open during wet stretches.

Along the way, you can spot a rock formation that looks like a caveman sitting on top of a flowstone wall. One stalagmite stands 27 feet tall but measures only about three inches wide.

Look up and you might catch ancient shark teeth embedded in the ceiling, left over from when a shallow sea covered Alabama.

Sift for rough-cut gems at the flume stations

Near the visitor center, the park runs gemstone mining at flume stations where you buy a bag or bucket of mining dirt seeded with rough-cut gemstones and fossils.

You dump the dirt into a custom-made flume, let running water wash away the sediment, and pick through what stays behind. A gemstone identification display near the station helps you figure out what you pulled.

Kids love it, but grown-ups get into it just as fast once the first stone shows up in the screen.

Five trails wind up Pisgah Mountain through hardwood forest

Above ground, the park has five color-coded hiking trails that total over five miles. They cut through hardwood forests of oak, beech, elm, poplar and maple on the slopes of Pisgah Mountain.

The Yellow and Green loop covers about 2.5 miles at a moderate grade and climbs high enough that you can see into nearby valleys once the leaves drop.

If you want something quick, the Red Trail near the visitor center is a short nature walk with wildlife signs along the way.

The park also hosts competitive trail races, including a half marathon in March and a 5K in September.

Camp under the trees or book a cabin

The park has improved campsites with full hookups, basic sites with water and electric, and primitive tent-only spots for people who want it simple.

If you’re willing to haul your gear about three-quarters of a mile, backcountry campsites are out there too. A bathhouse with restrooms and showers sits near the campground.

Go Camp Alabama operates cabins in the park for anyone who prefers a roof. Two large picnic pavilions near the welcome center give day visitors a place to spread out.

Sixty degrees underground, no matter the month

That constant 60-degree temperature inside the cave makes this place work in every season. In Alabama’s summer heat, the cave feels like walking into air conditioning.

In winter, it feels warm. The park stays open year-round with tours running daily, but you should reserve your cave tour ahead of time, especially on weekends and holidays.

If you want to make a longer trip out of it, Lake Guntersville, Monte Sano State Park, DeSoto State Park and the U.S. Space and Rocket Center in Huntsville are all close by.
