The name 'Kungsklyftan' (King's Cleft) originates from a 1887 visit by King Oscar II, whose name is carved into the rock face.
The boulders suspended above the walkway are held in place by friction against the vertical granite walls.
The site features a prominent iron staircase installed for safe passage through the narrowest sections.
The location serves as the fictional 'Wolf's Cleft' in Astrid Lindgren's Ronja the Robber's Daughter film adaptation.
The rock walls are composed of Bohus granite, which is roughly 920 million years old.
Kungsklyftan is a narrow, steep-walled natural cleft located at the base of Vetteberget mountain in the center of Fjällbacka. The site is famous for the giant boulders wedged between the rock faces, creating a subterranean-like passageway. It gained international prominence as a filming location for the Ronja the Robber's Daughter movie and the popular Camilla Läckberg crime novels. Wooden stairways and viewing platforms allow visitors to traverse the gorge and ascend to the mountain summit. The rock formations were created by seismic activity following the retreat of the last ice age. The gap separates the main village from the upper rocky plateau, offering a panoramic view of the Fjällbacka archipelago. It is a geological attraction accessible directly from the village harbor area.

Wear sturdy walking shoes with good grip as the rock surface can be slippery even in dry weather.
If you are claustrophobic, use the marked trail around the side of the mountain instead of going through the narrowest part of the cleft.
Bring a windbreaker, as the channel often creates a natural wind tunnel.

Stay on marked paths to avoid damaging the lichen on the rocks; climbing the loose boulders is strictly prohibited.
