Why caves have long been associated with fairies, hidden kingdoms, the Otherworld, and sacred crossings between realms in folklore and spiritual tradition.
There are few places on Earth that feel more mysterious than caves.
Step inside one and the world changes almost immediately.
The air grows cooler. Sound becomes strange and distorted. Sunlight fades behind you. Time seems to slow. The familiar landscape of ordinary life disappears, replaced by darkness, silence, and stone.
It’s no wonder that people throughout history have imagined caves as something more than geological formations.
Across Europe, the British Isles, Scandinavia, the Mediterranean, and beyond, caves have long been associated with fairies, spirits, gods, ancestors, hidden kingdoms, and journeys into other realms (Briggs, 1976; Eliade, 1959).
Folklore repeatedly describes caves as entrances to enchanted worlds that exist just beyond human perception.
These stories aren’t just entertaining legends. They reveal something profound about how human beings experience liminal spaces (places that exist between one state and another).
A cave is neither fully part of the surface world nor entirely separate from it.
It sits at the threshold. And thresholds have always been places of mystery.
For spiritual practitioners, folklorists, and lovers of myth, caves offer a fascinating lens through which to explore the idea of hidden worlds. Not necessarily as literal locations, but as symbolic realms of transformation, intuition, imagination, and encounter with the unknown.
In this article, we’ll explore the rich folklore surrounding caves as portals, examine fairy traditions from around the world, and look at how modern practitioners can work respectfully with cave symbolism as a spiritual tool.

Why Humans Associate Caves with Hidden Worlds
Long before scientific explanations existed, caves inspired awe.
Archaeological evidence suggests that caves held ritual significance for many prehistoric cultures, including those responsible for the famous cave paintings of France and Spain (Lewis-Williams, 2002).
Some scholars propose that caves were viewed as sacred spaces connected to spirit worlds, ancestors, or visionary experiences (Clottes & Lewis-Williams, 1998).
Even without formal religious beliefs, caves kind of naturally evoke feelings associated with mystery.
Psychologists sometimes refer to this as the “numinous” experience. That’s a sense of encountering something larger, deeper, or more mysterious than everyday reality (Jung, 1964).
Several characteristics contribute to this perception:
- Darkness limits ordinary perception.
- Silence encourages inward awareness.
- Physical separation creates a sense of entering another realm.
- Unusual geological formations appear otherworldly.
- Altered acoustics create strange sensory experiences.
In many ways, caves may feel like places where ordinary rules no longer apply.
Folklore often took this feeling and gave it narrative form. If a place felt different, perhaps it connected to a different world.
I’ve written a bunch about caves (I turn 50 in 2026, so it’s my Chiron return and I’m going deep this year.) Take a gander:

Fairy Realms and the Hidden World
One of the most widespread themes in European folklore is the existence of an Otherworld inhabited by supernatural beings (Briggs, 1976).
These beings were known by many names:
- Fairies
- Sidhe
- Good Neighbors
- Huldufólk (the Hidden Folk of Iceland)
- Elves
- Nature spirits
Despite regional differences, many traditions describe these beings as existing alongside humanity while remaining largely invisible.
Their world wasn’t necessarily far away. It was simply hidden. (Some might say it’s right next door, or layered right on top of our reality, but that’s a topic for another post…)

According to many stories, fairy kingdoms existed:
- Beneath hills
- Under mountains
- Within ancient mounds
- Beyond lakes
- Inside caves
- Through invisible doorways
The boundary between worlds was often remarkably thin (Evans-Wentz, 1911).
A person might stumble into a fairy realm while hunting, herding animals, gathering herbs, or seeking shelter in a cave.
One wrong turn could lead somewhere entirely unexpected.

The Irish Sidhe and Their Underground Kingdoms
So, maybe the best-known cave-related fairy traditions come from Ireland.
In Irish mythology, the Sidhe are supernatural beings associated with ancient burial mounds, hills, and subterranean realms (MacKillop, 2004).
After the arrival of the Milesians, the divine race known as the Tuatha Dé Danann were said to retreat beneath the land itself, dwelling within hidden realms inaccessible to ordinary humans (MacKillop, 2004).
These underground kingdoms were not portrayed as dark or unpleasant places.
Instead, they were often described as beautiful, timeless, and filled with abundance.
Many cave entrances, rocky hillsides, and unusual geological features became associated with gateways to these hidden domains.
Stories frequently warned travelers not to disturb such places.
Removing stones, damaging formations, or showing disrespect toward certain sites could invite misfortune from the beings believed to dwell there (Briggs, 1976).
Whether taken literally or symbolically, these traditions reflect a profound respect for the unseen dimensions of landscape.
Fairy Caves of Scotland and the British Isles
Scotland preserves numerous legends surrounding caves and fairy dwellings.
Many coastal caves were believed to serve as entrances to fairy kingdoms hidden beneath mountains or beneath the sea (Briggs, 1976).
The Isle of Skye is famous for fairy lore associated with rugged landscapes, caves, and unusual rock formations.
In some traditions, caves functioned as meeting places between worlds.
A person might hear music emerging from within the stone. They might encounter mysterious lights. They might discover a doorway that appeared only under specific conditions.
One recurring theme involves altered time.
Individuals who entered fairy realms often returned believing only hours had passed, only to discover years (or even centuries, yikes!) had elapsed in the outside world (Briggs, 1976).
This motif appears across many cultures and reflects enduring human fascination with the nature of time, consciousness, and reality itself.
Iceland’s Hidden Folk and Mountain Portals
Icelandic folklore offers another really cool example.
The Hidden Folk, or Huldufólk, are said to inhabit mountains, lava fields, cliffs, and caves (Hastrup, 1990).
Unlike many modern portrayals of fairies, these beings were often regarded as neighbors sharing the landscape rather than purely fantastical creatures.
Stories describe entire hidden communities living within rocky formations.
Some traditions held that specific caves functioned as entrances to these concealed settlements.
Even in contemporary Iceland, respect for sites associated with Hidden Folk remains part of cultural folklore and identity (Hastrup, 1990).
Whether people interpret these stories literally or symbolically, they reveal a worldview that sees landscape as alive, meaningful, and filled with mystery.
Why Threshold Spaces Were Considered Powerful
To understand cave lore, it’s helpful to understand the concept of liminality.
Anthropologist Victor Turner described liminal spaces as transitional zones where ordinary structures temporarily dissolve (Turner, 1969). For example:
These locations exist between categories. They’re neither one thing nor another.
Because of this ambiguity, folklore often portrays them as places where transformation becomes possible.
Caves might be one of the most powerful examples.
They exist between surface and underground. Between light and darkness. Between the known and the unknown.
For many traditions, this made them ideal locations for encounters with spirits, visions, ancestors, and magical beings.
Caves, Dreams, and Altered States
Many cave legends contain dreamlike qualities.
Travelers lose track of time. Reality becomes fluid. Impossible events occur.
The experience often resembles a visionary journey more than a physical spelunking adventure.
Some researchers have suggested that caves naturally encourage altered states of awareness through sensory reduction and prolonged darkness (Lewis-Williams, 2002).
When external stimulation decreases, attention often turns inward. Dreams, intuitions, memories, and symbolic imagery can become more vivid.
This may help explain why caves repeatedly appear in myths involving:
- Prophecy
- Spirit encounters
- Initiation
- Revelation
- Fairy contact
- Divine messages
In symbolic terms, entering a cave resembles entering the unconscious mind.
The journey inward becomes a journey downward. And what waits in the darkness is often hidden knowledge.

The Fairy Otherworld as a Symbol
Modern readers sometimes ask whether ancient people “really believed” fairy realms existed.
So, the answer is complicated.
Beliefs varied widely across cultures, regions, and historical periods. But from a symbolic perspective, one way to understand fairy realms is as representations of hidden dimensions of experience.
The Otherworld often embodies:
- Mystery
- Imagination
- Creativity
- Nature’s intelligence
- Spiritual transformation
- Encounters with the unknown
When you look at it this way, cave portals may represent moments when ordinary awareness expands.
A doorway opens. Something previously unseen becomes visible. A person returns changed.
This pattern appears repeatedly in myths worldwide. The physical cave serves as the outer landscape for an inner journey.

Caves in Modern Spiritual Practice
Today, many spiritual practitioners continue to feel drawn to cave symbolism.
This doesn’t require believing in literal fairy kingdoms (although it certainly can).
Instead, caves can function as powerful archetypal images. A cave meditation, for example, might involve visualizing yourself entering a cavern and discovering a hidden chamber.
- What appears there?
- A guide?
- A treasure?
- A message?
The imagery itself can become a tool for reflection.
Many practitioners also work with cave symbolism through:
- Journaling
- Pathworking
- Dream work
- Meditation
- Storytelling
- Seasonal rituals
- Ancestral practices
The goal isn’t proving the existence of hidden realms. Think of it more as engaging with symbols that have inspired human imagination for thousands of years.
A Cave Portal Meditation for Reflection
If cave symbolism resonates with you, try this simple meditation.
Find a quiet space and close your eyes.
Imagine standing before the entrance of a cave.
Notice:
- What the cave looks like
- Whether you feel curious or hesitant
- What sounds you hear
- Whether light or darkness waits inside
Slowly imagine yourself entering.
As you walk deeper, allow a chamber to appear naturally.
In that chamber, ask: “What wisdom am I ready to discover?”
Don’t force an answer.
Just observe what comes up for you.
When you’re ready, retrace your steps and return.
Afterward, write down anything that stood out. (Try not to self edit, just get your thoughts down.)
Images often reveal meaning gradually over time.
Why Caves Continue to Fascinate Us
Thousands of years after the first stories were told, caves still captivate the human imagination.
Maybe it’s because they embody one of our deepest questions: What lies beyond what we can currently see?
Whether understood as entrances to fairy kingdoms, symbols of the unconscious, sacred landscapes, or threshold spaces between worlds, caves remind us that mystery remains an essential part of human experience.
Not every doorway leads somewhere visible. And not every journey happens in the physical world.
Sometimes the most important portals are the ones that invite us to look inward.
And maybe that’s why caves continue to appear in myths, dreams, spiritual traditions, and folklore across cultures.
They remind us that hidden worlds (whatever form they take) have always been waiting just beyond the edge of the known.
