Gröntjärn, Nature reserve and spring in Hudiksvall Municipality, Sweden
The reserve spans across a narrow valley encircled by mountains, featuring a pond with water levels that naturally fluctuate by 13 meters.
The formation of Gröntjärn dates to 8500 years ago when melting ice sheets created specific geological structures and death ice pits.
The reserve functions as an outdoor educational center where local communities gather to learn about natural heritage and environmental conservation.
Visitors can access marked trails, shelters, grilling areas, a forestry cabin, restrooms, and parking facilities within the 150-hectare protected area.
The water in Gröntjärn pond displays turquoise colors and contains glacial relict plants such as mountain carnations along its shores.
