The Moon Caves at Cathedral Gorge State Park are narrow slot passages in the park’s bentonite clay formations, accessible from the main day-use area near the picnic sites. They’re a short exploration stop at 0.2 miles / 26 feet of gain rather than a traditional hike. The caves are not actual caves; they’re deep narrow slots formed by erosion in the soft clay, twisting and connecting in a maze character that creates a substantially different experience from simply walking past the formations from outside.

At 0.2 miles, this is better understood as a companion stop to the Juniper Draw Loop Trail (3.3 miles / 216 ft) rather than a standalone hike. The two together give a complete Cathedral Gorge day: the loop for the full park landscape, the Moon Caves for the slot character that the park is famous for.

Quick Facts

How to Get There

Cathedral Gorge State Park is near Panaca, Nevada, on US-93 in southeastern Nevada.

From Las Vegas, take I-15 north to US-93 north, approximately 3 hours.

From St. George, Utah, take I-15 north to US-93 north, approximately 2.5 hours.

From Ely, Nevada, US-93 south approximately 1 hour. Once in the park, head to the main day-use picnic area where the Moon Caves access is signed.

Parking Information

Parking at the day-use picnic area near the cave access. Rarely fills given Cathedral Gorge’s relative obscurity. Park entry fee ($5 Nevada / $10 non-Nevada) applies. Restrooms at the day-use area.

Cell Service and Navigation

Cell coverage is limited in southeastern Nevada. Download AllTrails offline before leaving Panaca. The Moon Caves access is signed from the day-use area; navigation to the entrance is straightforward. Inside the passages, have the GPS position noted so you can orient yourself on the way out.

What to Expect Inside the Moon Caves

The Moon Caves are narrow slot passages through Cathedral Gorge’s bentonite clay formations. The clay material produces a different slot character from Utah’s sandstone: the walls are smoother, the erosion patterns are different, and the color is paler, cream and beige rather than the saturated oranges of sandstone canyons. The passages twist and connect unpredictably, creating the maze-like character that makes the caves worth exploring slowly rather than rushing through.

Some sections require squeezing through sideways. Some require ducking. Some open into small chambers where the sky is visible overhead through a slot opening. The overall character is physically engaging in a way that a passive viewpoint isn’t: you’re navigating the formations rather than observing them from outside.

The bentonite clay that forms the Moon Caves is significantly more fragile than sandstone. Do not lean on, push on, or grip the canyon walls; the clay is easily damaged by hand pressure. Do not attempt to enter the caves when the clay is wet, wet bentonite is extremely slippery, the passages become mud, and the formations are most vulnerable to erosion when saturated. Rain closes the caves to safe access immediately; avoid the caves for at least 24-48 hours after any precipitation.

Photography

The slot character, narrow sky strips overhead, textured clay walls in close proximity, is the primary photography subject inside the Moon Caves. Morning light from the east reaches the slot openings before midday; the light filters into the passages at specific angles that produce the characteristic slot canyon light shafts. Wide-angle for the passage width and the overhead sky, mid-range for the clay wall texture and the passage character. A headlamp or small light source helps illuminate the darker passage interiors for photography.

Trail Difficulty and Length

The route is 0.2 miles with 26 feet of gain. Easy is accurate for the physical demands of the passages in dry conditions. The tight sections that require squeezing are accessible for most adults; people with claustrophobia or significant size restrictions may not be comfortable in the narrowest passages. Budget 30-60 minutes for the exploration depending on how many passages you navigate.

Dog Friendly?

Yes. Dogs are permitted on leash. The tight passages may not be wide enough for larger dogs; assess as you enter. Dogs cannot squeeze through sections where humans go sideways; manage the route to stay in dog-accessible sections if exploring with a dog. No water in the caves; bring water for dogs.

What to Bring

Water: even for a short stop in the desert. A headlamp or small flashlight for the darker passage sections. Clothes you don’t mind getting clay-dusted. Sturdy shoes for the uneven clay floor. No special equipment needed.

Best Time to Visit

October through April for comfortable temperatures. The cave interiors are noticeably cooler than the desert surface, which makes them a pleasant afternoon stop in summer heat if the approach is managed with an early start. Never visit when rain is forecast or within 24-48 hours of rain. Sunrise and sunset light enters the slot openings at the most dramatic angles, golden hour is the photography priority timing.

Rules and Regulations

Do not touch or grip the clay walls. Do not visit when wet. Stay in designated exploration areas. Leave No Trace throughout. Pack out all trash. Dogs on leash. $5 Nevada / $10 non-Nevada entry fee.

Nearby Adventures

The full Cathedral Gorge catalog: Juniper Draw Loop Trail (3.3 miles / 216 ft), the primary park loop through open desert and slot canyon passages; Millers Point (0.5 miles / 111 ft), the panoramic overlook; and Hawk’s Ridge Trail (4.2 miles / 278 ft), the longer ridge route. The Moon Caves and the Juniper Draw Loop together cover the Cathedral Gorge experience in a complete day visit.

Kershaw-Ryan State Park in Caliente and Echo Canyon State Park are the other southeastern Nevada state parks within reach from Cathedral Gorge. Pioche, Nevada (about 10 miles from Panaca) adds a genuine Wild West history stop with the million-dollar courthouse and Boot Hill Cemetery.

Chase the Quiet

The Moon Caves are 0.2 miles of clay passages that took thousands of years to form and can be closed by a single afternoon of rain. They’re one of the more specific and fragile things in the American West to be inside. The tight passage walls, the pale clay, the sky visible through the slot above, it’s a contained and complete experience that doesn’t require distance or elevation to deliver. Cathedral Gorge is already the quieter version of the Colorado Plateau’s canyon country. Inside the Moon Caves, it gets quieter still.
