Discovering the Hidden Wonders Behind Caves of Zion National Park

Zion National Park has no shortage of dramatic rock formations, winding trails, and hidden spots waiting to be discovered. Among its lesser-known features, the park’s caves offer an entirely different experience.

Some are tucked away in towering cliffs, while others require a bit of effort to reach, rewarding those who seek them out with stunning natural formations and a sense of solitude. It really is something you need to visit if you’re in this part of the US.

I’ve always been fascinated by these spaces, carved over thousands of years, and shaped by wind, water, and time. Some hold fascinating geological features, while others serve as quiet retreats away from the more crowded areas of the park.

Before heading out, it’s important to know what to expect. Some caves are accessible with a short hike, while others demand scrambling over rocks or squeezing through narrow passages.

1. Mammoth Cave (Highly Recommended)

Mammoth Cave is the longest lava tube in Utah, stretching over 2,100 feet and offering a variety of passages to navigate. With its spacious chambers and multiple access points, the cave provides an exciting challenge for those looking to experience a raw, underground environment.

The rocky terrain and occasional low ceilings make a helmet and headlamp essential for a safe visit.

Both entrances to the cave are conveniently located near the parking area, leading to different routes through the lava tube. The largest chamber is a favorite stop, with enough room to take in the surroundings and appreciate the natural forces that shaped this underground formation.

The temperature drops significantly inside, so bringing an extra layer is a good idea.

For those seeking an authentic caving experience, Mammoth Cave is a top choice. The terrain shifts between open spaces and tighter corridors, creating an exciting mix of easy walking and light scrambling.

Unlike some of the more popular attractions in Zion, like Zion National Park, this location offers a quieter setting, perfect for those who enjoy a bit of adventure without heavy crowds.

2. Upper Red Cave (Not Advised)

Upper Red Cave offers a dramatic slot canyon experience, but reaching it is no easy feat. Located east of Mount Carmel, this cave requires navigating steep terrain, unpredictable conditions, and technical challenges that even experienced hikers find demanding.

Unlike more accessible areas, this one comes with a higher level of risk, making it an option that most visitors should reconsider.

Reaching the entrance involves trekking through rugged surroundings, where flash floods, loose rocks, and narrow passages add to the difficulty.

The canyon itself is breathtaking, with towering walls that shift in color throughout the day, but the effort required to get there, and more importantly, to get back, should not be underestimated.

Those who attempt the route should have solid backcountry experience, a strong awareness of weather conditions, and the physical endurance to handle demanding terrain.

Slipping hazards, sudden elevation changes, and sections requiring careful foot placement make this location particularly unforgiving.

3. Birch Hollow Slot Canyon (Not Advised)

Birch Hollow Slot Canyon is a technical route that demands skill, preparation, and proper equipment.

Nestled within the Grand Staircase-Escalante National Monument, this canyon presents an exciting challenge with its steep descents, tight sandstone walls, and stretches of ankle-deep water.

It attracts experienced canyoneers who thrive on rappelling and navigating rugged terrain, but it is far from an ideal choice for those without the necessary skills.

The route consists of multiple rappel sections, some exceeding 100 feet, requiring technical expertise and confidence in rope work. Loose rock and narrow passages can make movement tricky, increasing the risk for those who are unprepared.

Flash flooding is another serious consideration, as the canyon’s confined spaces leave little room for escape during heavy rainfall.

While Birch Hollow provides an exciting test for experienced adventurers, it presents significant hazards for those unfamiliar with technical canyoneering.

Those who decide to take on this route should go with a well-equipped group, check weather conditions carefully, and have a solid grasp of necessary skills before attempting the descent.

4. Moqui Cave (A Must-Visit)

Moqui Cave, also known as the Kanab Sand Cave, offers an incredible mix of history, geology, and adventure. Located just five miles outside of Kanab, this sandstone wonder sits conveniently along the main highway leading to Bryce Canyon and Zion National Park.

Despite its proximity to well-traveled roads, it retains an air of seclusion, giving visitors a chance to experience something extraordinary without the usual crowds.

While the hike itself is short and relatively simple, reaching the cave requires a semi-steep climb. Proper footwear is essential, as loose sand and rock can make the ascent trickier than expected.

Once inside, the atmosphere shifts dramatically, the sun casts a warm glow on the sandstone walls, creating a striking contrast against the cave’s darker recesses.

The best times to visit are early morning or late afternoon when the lighting enhances the natural beauty of the cave’s interior. Bringing water and snacks is a good idea, especially during warmer months, as the trail lacks shade.

For those who love photography, Moqui Cave provides endless opportunities, with its smooth, curved walls creating a perfect natural frame for the desert sky.

5. Peekaboo Slot Canyon (Highly Recommended)

Peekaboo Slot Canyon, located near the town of Kanab, offers a quieter alternative to some of the more heavily visited slot canyons in the region.

The towering red rock walls create a stunning contrast against the desert sky, and the narrow passageways wind through smooth sandstone, giving hikers a sense of adventure without requiring technical climbing skills.

Unlike some other slot canyons that require ropes or advanced scrambling, Peekaboo Slot Canyon is relatively accessible. The hike itself involves walking through a sandy wash before reaching the narrow sections, where the walls rise dramatically on both sides.

Light filters through in fascinating ways, shifting throughout the day and casting intricate patterns on the rock.

Because it’s lesser-known compared to other famous canyons, it provides a quieter experience. Hikers can take their time, appreciating the curves and textures of the rock without the rush of large crowds moving through.

The path is straightforward, though loose sand can make certain sections more tiring. Proper footwear and plenty of water are essential.

For those who prefer a bit of solitude while still enjoying striking desert scenery, Peekaboo Slot Canyon is an excellent choice. It delivers all the excitement of a classic slot canyon hike while allowing visitors to appreciate the natural surroundings at their own pace.

6. Belly of the Dragon (Highly Recommended)

A short drive away from Zion National Park, Belly of the Dragon offers an exciting hiking experience with a distinct atmosphere. Originally carved as a water drainage tunnel beneath Highway 89, this passage has become a popular spot for those looking to explore something different.

Over time, erosion has shaped the tunnel’s walls, creating flowing patterns and textures that add to its visual appeal.

Belly of the Dragon is an accessible and family-friendly hike. The tunnel’s winding path, with its natural curves and shadowed recesses, makes for a fun and slightly mysterious walk. Since light doesn’t reach the entire passage, a flashlight is recommended to help navigate the darker sections.

Once inside, the tunnel provides a cool and shaded retreat, making it an excellent option during warmer months. While the hike itself is not long or strenuous, footing can be uneven in certain areas, so sturdy shoes are advisable.

Some sections may require stepping over small obstacles, but overall, this is a welcoming adventure for all skill levels.

For those seeking an interesting spot for photography, Belly of the Dragon offers an atmospheric setting with shifting light patterns as the sun moves overhead.

The combination of carved walls, filtered sunlight, and the sense of seclusion makes this a memorable stop just outside Zion’s main attractions.

7. The Narrows (Highly Recommended)

The Narrows is one of the most famous and demanding hikes in Zion National Park, offering an unforgettable experience of trekking through water while surrounded by towering canyon walls.

Unlike traditional trails, this route takes hikers directly through the Virgin River, requiring balance, endurance, and a willingness to get wet.

Starting at the Temple of Sinawava, the hike extends up to 16 miles, with sections where water can reach waist level. The sheer rock faces on either side rise dramatically, creating an enclosed and awe-inspiring environment.

Since much of the trek involves wading through the river, proper footwear and preparation are essential.

The best time to attempt The Narrows is mid-summer through early fall when water levels in the Virgin River drop, making conditions more manageable. Flash floods are a real hazard, so checking forecasts and park warnings before setting out is crucial.

This hike is more than a test of endurance—it’s an experience that demands patience and caution while rewarding hikers with incredible views at every turn.

The shifting light reflecting off the high walls, the cool water flowing underfoot, and the winding path through the canyon make The Narrows a bucket-list adventure for those willing to take on the challenge.

8. Weeping Rock (Highly Recommended)

Weeping Rock offers a short yet memorable hike that leads to a beautiful rock alcove where water continuously seeps through the sandstone. Over time, this process has nourished a thriving patch of greenery, creating a striking contrast against the rugged red rock surroundings.

The trail is just 0.4 miles round trip, making it an excellent choice for families, beginners, or anyone looking for a brief but rewarding walk.

Despite its short length, the hike provides a refreshing break, especially during warmer months. The constant flow of water creates a misty environment that helps cool the air, making it a comfortable stop along any park visit. The rock face is often covered with ferns and moss, giving the area a lush, almost hidden-garden feel.

Standing beneath the alcove, visitors can watch as droplets form and trickle down in a slow, rhythmic pattern, a result of rainwater filtering through the porous sandstone over thousands of years.

The natural process gives Weeping Rock its name and its peaceful atmosphere. It’s a great place to pause, take in the surroundings, and appreciate one of Zion’s quieter scenic spots.

9. Hidden Canyon (Not Advised)

Hidden Canyon pushes hikers to their limits with its demanding terrain and adrenaline-inducing heights. The path clings to the side of towering cliffs, with steep drop-offs that leave little room for error.

Chains bolted into the rock provide necessary support in some of the trickier sections, but those with a fear of heights may find parts of the trail overwhelming. The narrow ledges and sharp inclines demand balance, confidence, and a steady pace.

For those prepared to take on the challenge, Hidden Canyon delivers unforgettable views and a thrilling sense of accomplishment. The dramatic rock walls and occasional glimpses of wildlife add to the experience, rewarding those who push through the strenuous ascent.

Given the level of difficulty, this trail is not recommended for beginners or those seeking a casual hike. Proper preparation and awareness of one’s limits are key to making the trek both safe and enjoyable.

10. Keyhole Canyon (Highly Recommended)

Keyhole Canyon delivers an adrenaline-packed experience for those willing to take on its technical challenges. This short but demanding slot canyon requires more than just hiking, rappelling, swimming through icy pools, and maneuvering through narrow passages all come into play, located near Zion National Park.

While the distance may seem manageable, the physical effort and necessary skills make this an undertaking best suited for experienced canyoners or those guided by professionals.

The experience begins with a short approach, but things escalate quickly as the walls tighten, and the terrain demands careful navigation. Expect sections where you’ll be waist-deep in frigid water, sometimes fully submerged, depending on recent rainfall and seasonal conditions.

A wetsuit is highly recommended, as the water remains cold year-round, and hypothermia can set in quickly for those unprepared.

Each rappel varies in height, with some drops requiring careful rope work in confined spaces. The final section features a series of pools where wading or swimming is unavoidable. Sunlight barely reaches certain parts of the canyon, adding to the sense of adventure.

The rock formations showcase layers of erosion, creating intricate textures and patterns that make every turn visually striking.

Summary

Zion National Park caves offer something different for those willing to seek them out.

Some provide a quiet escape, while others challenge visitors with rugged terrain and technical routes. Each one tells a story of time, erosion, and the forces that shaped the region.

Preparation is key, knowing the routes, bringing the right gear, and respecting park regulations help protect these natural spaces for future visitors.
