Lipno Tree Tower, Czech Republic

The first treetop walkway in the Czech Republic opened in Lipno in 2012. The path is 2,214.5 ft long and leads to a tree tower.

On the top platform, at a height of 131 ft, visitors can enjoy the wonderful view from the wooden lookout over Šumava National Park and Lipno Dam on the Vltava River.

Tree Tower

The tower construction consists of an external circular ring based on nine glued-laminated timber columns which have been arranged in rotational symmetry and set up with an angle difference of 40° each, thus forming a polygonal, spatial structure.

A steel pylon made of a round pipe was built inside the tower. Steel spiral stairs with steel grids and a tunnel slide are attached to the pylon, which is connected to the tower at two height levels: at 78.7 ft and 131.2 ft.

Visitors have access to the tower using the treetop walkway, ending at 78.7 ft above the ground, or climbing the spiral staircase. From there, they can reach the viewing platform by climbing a spiral timber construction that is attached to the timber columns by means of cantilevered steel beams.

The construction has been stiffened by a close mesh of diagonal steel members anchored in the timber columns. Furthermore, four horizontal ring constructions consisting of steel pipes have been arranged in the lower part of the tower.
