Potholes

Nature's Own Water Park – Polished Rock Slabs, Round Potholes, and Crystal Clear Pools.

In the south of Nissedal, near Espestøyl farm, the Fyresåna river has polished the mountain into spectacular potholes (jettegryter), natural slides, and tranquil pools. When the sun warms the rock, Jettegrytene becomes a natural summer land – perfect for swimming, picnics, photos, and great memories.

Experience Jettegrytene

Along a stretch of approximately 300 meters, the potholes are densely packed – from small "footbaths" to deep pools and natural slides. The narrow valley and the warm rock slabs give you a genuine "Sørlandet" (Southern Norway) feeling. Jettegrytene has been a local favorite for generations and is today among Nissedal's most photographed natural phenomena, and has been named Telemark's finest swimming spot several times.
