Styggforsen Travel Guide

Styggforsen reveals itself as a powerful 36-meter waterfall where the Styggforsån river plunges through a steep canyon, carving through layers of ancient rock. The cascade drops dramatically, exposing granites from primordial times on one side and younger sedimentary strata from a long-lost tropical sea on the other. Mist rises from the base, where the water meets a rugged dike of brecciated quartz, creating a symphony of roaring sound and shimmering spray that draws the eye upward to the forested rim.This geological spectacle sits at the eastern fringe of the Siljan Ring, a vast prehistoric impact crater formed 377 million years ago by a massive bolide strike. The event reshaped the landscape, forming bedrock depressions that birthed features like Lake Siljan and this very waterfall, composed partly of Ordovician limestone columns.

The Siljan Ring's origins trace to the Devonian period, when a 4-kilometer-wide meteorite slammed into Earth at 100,000 km/h, realigning rock strata and etching enduring scars into the terrain. Styggforsen's canyon walls bear witness, with horizontal layers tilted vertically by the force, interspersed with impact-altered quartz breccias predating the event. Over eons, glacial and fluvial erosion sculpted the gorge, amplifying the site's raw, otherworldly presence.Today, the reserve preserves these formations, allowing visitors to trace millions of years of Earth's turbulent history in a single vista. The interplay of forces—cosmic collision, ancient seas, ice ages, and relentless water—makes Styggforsen a living textbook of planetary evolution.

Encircling the falls, a damp old forest thrives in the misty microclimate, blanketed in rare mosses, lichens, and delicate ferns. The 12-hectare nature reserve, established in 1979 and later integrated into Europe's Natura 2000 network, harbors unique flora like the striking Epipactis atrorubens orchid, alongside purple knotweed and spider flowers clinging to rocky outcrops.Insects buzz in abundance, including species such as Venusia cambrica, Hyloicus pinastri, and Epirrhoe alternata, sustained by the area's protected wetlands and shaded glades. Strict rules prohibit picking plants or disturbing the habitat, ensuring this verdant sanctuary endures for future explorers.

A well-marked 1km circular path winds from the parking area, descending via constructed stairs and boardwalks to viewpoints hugging the canyon edge. The route offers glimpses of the thundering drop, misty pools below, and overhanging cliffs shrouded in greenery. Midway, it leads to the Troll Hole—a shadowy cave carved into the rock, steeped in local folklore where mythical beings are said to dwell.The trail balances accessibility with immersion, featuring interpretive signs detailing the site's geology and ecology. Wooden bridges span streams, and railings guide along steeper sections, making the loop suitable for moderate hikers seeking nature's raw theater.

Styggforsen's eerie beauty captured Ingmar Bergman's imagination, serving as a filming location for his 1960 film The Virgin Spring, infusing the site with cinematic mystique. Local legends amplify its mythical aura, portraying the canyon as a portal to troll realms, with the cave as their hidden lair.Seasonally, a nearby café operates in summer, offering refreshments amid the woodland setting, while an information center provides deeper insights into the reserve's wonders. These touches blend natural reverence with subtle human narrative.
