What Is a Troll?

A Troll is a legendary creature from Norse and Scandinavian folklore. Depending on the story, a troll may be a towering giant, a mountain-dwelling monster, or a magical nature spirit living deep within forests and caves.

Trolls have appeared in Scandinavian legends for over a thousand years. Early stories often described them as ancient beings connected to rocks, mountains, and wilderness. Some trolls were dangerous and disliked humans, while others simply preferred to be left alone in the wild.

One of the best-known beliefs says that trolls turn to stone if caught in the sunlight — a legend inspired by the many unusual rock formations found throughout Norway and Sweden. Modern fantasy has introduced many new versions, but traditional folklore portrays trolls as mysterious creatures with tremendous strength and a deep respect for nature.

The Troll stands alongside the yeti, bigfoot, and the kelpie as one of folklore's most iconic creatures. Explore the full mythical creatures guide to discover more.

Appearance

What Does a Troll Look Like?

Trolls vary greatly in appearance depending on the legend. Some resemble enormous giants, while others look more like rough, human-shaped creatures with magical features — all powerfully built for life in the rugged Scandinavian wilderness.

Large Humanoid Body

Most trolls have broad shoulders, muscular bodies, and towering heights — built for surviving the harsh mountains and forests of Scandinavia.

Long Arms

Many stories describe trolls with unusually long, powerful arms that help them climb cliffs, lift boulders, and defend their homes.

Thick Skin

A troll's skin is often rough like stone or tree bark, protecting it from harsh weather and making it very difficult to injure.

Sharp Teeth

Many trolls possess large, pointed teeth — intimidating features that reinforce their reputation as fierce wilderness creatures.

Powerful Hands

Strong hands allow trolls to move massive boulders, climb mountains, and build homes inside caves or rocky hillsides.

Stone-Like Features

Some trolls have skin so rough and gray it looks almost like living rock — a clue to the legend that sunlight can turn them into stone.

Gray Troll

Gray trolls resemble stone and are commonly associated with mountain cliffs and rocky caves throughout Norway.

Brown Troll

Brown trolls blend into forests and woodland environments, helping them remain hidden from humans.

Green Troll

Modern fantasy often portrays trolls with green skin to emphasize their connection with forests, moss, and nature.

How Big Is a Troll?

Regeneration

Some legends give trolls the ability to heal rapidly, making them extremely difficult to defeat in battle.

Shape-Shifting

Certain Scandinavian stories describe trolls disguising themselves as humans — or magically resembling rocks, trees, or hillsides.

Mythology

Troll Mythology Around the World

From the mountains of Norway and the forests of Sweden to the lava fields of Iceland, troll legends have shaped Scandinavian folklore for over a thousand years.

Norwegian Mountain Trolls

Norwegian legends describe enormous trolls living high in the mountains, guarding hidden caves, ancient treasures, and remote valleys.

Swedish Forest Trolls

Many Swedish stories describe trolls living in dense forests — closely connected to trees, moss-covered rocks, and quiet wilderness.

Icelandic Lava Trolls

Icelandic folklore places trolls among dramatic lava fields and volcanic landscapes, hiding among black rocks and glaciers.

Hidden Valleys

Deep valleys surrounded by towering mountains were believed to be perfect hiding places for trolls, far from human eyes.

Woodland Spirits

Some Swedish traditions portray smaller trolls as nature spirits that protect forests and avoid unnecessary contact with humans.

Giant Folklore

Modern Mythology

Why Do Trolls Turn to Stone?

One of the best-known troll legends says that sunlight turns trolls into stone. According to Norse and Scandinavian folklore, trolls are creatures of the night — if they remain outdoors after sunrise, the first rays of sunlight cause their bodies to harden into solid rock.

Many famous cliffs, giant boulders, and unusual stone formations throughout Norway and Sweden were once believed to be trolls caught by the morning sun. Historians believe these stories helped explain dramatic landscapes long before geology was understood.
