The staircase reaches a maximum incline of 45 degrees in its steepest sections.
Construction of the wooden stairs began in 1918 to support the installation and maintenance of the massive water pipes.
There are markers every 500 steps to help hikers track their progress toward the summit.
The stairs are part of the original infrastructure that powered the first hydroelectric plant in Flørli, which was completed in 1917.
The path leads to a high mountain plateau that links to the regional Norwegian Trekking Association (DNT) trail network.
Flørlitrappene is the world's longest wooden staircase, consisting of 4,444 steps rising from sea level to an elevation of 740 meters. Built alongside the historic penstock pipes of the Flørli hydroelectric power station, the stairs follow the steep terrain of the Lysefjord mountains. The structure was originally constructed in the early 20th century as a maintenance path for workers servicing the water pipeline. The trail concludes at the top of the mountain, offering panoramic views over the Lysefjord and the surrounding highland plateau. Visitors climb through a mix of wooden and steel sections, gaining significant elevation in a short horizontal distance. The stairs are located in the roadless village of Flørli, which is accessible only by boat or hiking. The surrounding area features the decommissioned power station buildings, which now serve as a cultural hub and gallery space.

Wear sturdy hiking boots with excellent grip, as the wooden planks can be slippery when wet.
Bring windproof and waterproof clothing, as weather conditions at the summit can shift rapidly compared to sea level.
Carry sufficient water and snacks, as there are no amenities along the staircase path itself.
Do not attempt to descend the stairs, as it puts extreme strain on the knees and is discouraged by local guides; take the marked mountain hiking trail down instead.
The stairs are inaccessible during winter and spring due to heavy snow and ice; generally open from late spring through early autumn depending on melt.
Hikers are expected to keep to the right and allow faster climbers to pass at designated wider sections. Do not lean on the aged wooden railings.
