The Högvadsån river, which runs through the reserve, is considered one of Sweden's most important spawning rivers for wild salmon.
The reserve contains traces of an old water-driven mill and a power plant dating back to the early 20th century.
The river valley provides a habitat for the European otter and the dipper, a bird species that feeds underwater in the rapids.
The landscape was historically shaped by the movement of glaciers during the last ice age, leaving behind large erratic boulders.
Sumpafallen acts as a crucial ecological corridor connecting the inland forests with the coastal regions of Halland.
Sumpafallen Nature Reserve is a designated protected area situated along the Högvadsån river, known for its series of rapids and historically significant waterfall. The reserve protects a unique ecosystem that serves as a vital spawning ground for the rare North Sea salmon. Visitors can explore the area via a marked hiking trail that follows the riverbank through a varied landscape of mixed deciduous forest and open pastures. The site features the remains of a former power plant and mill, reflecting the industrial history of the river. The terrain is characterized by large boulders and turbulent water flow caused by the river's descent. The reserve is managed by the County Administrative Board of Halland to preserve its biodiversity and geological features.
The viewing platform near the main falls provides the best vantage point for capturing the rapids.
