The tower is officially classified as a combined telecommunications mast and tourist observation structure.
The base of the tower is anchored in the granitic bedrock characteristic of the Písek mountains.
The structure reaches a total height of 45 meters, but the observation gallery is located at the 30-meter level.
Jarník hill is the second-highest point in the Písek Mountains, surpassed only by Velký Mehelník.
Construction was financed primarily by mobile telecommunications operators to secure signal coverage in the region.
Jarník is a 45-meter tall steel telecommunications tower featuring a public observation deck located on the summit of Jarník hill in Písek. Situated at an elevation of 609 meters above sea level, the tower offers panoramic views of the Písek Mountains and the Otava River valley. The structure, completed in 1997, functions primarily as a broadcast transmitter for mobile networks. Visitors access the viewing platform via a spiral staircase consisting of 182 steps. The site sits within a dense forest area known as the Písecké hory, which is managed for both forestry and recreational hiking. The area serves as a local focal point for endurance athletes and cyclists traversing the forest trail network.
