Noteworthy stairs:

  • The Ha’iku Stairs, on the island of O’ahu, Hawai’i, are approximately 4,000 steps which climb nearly 1/2 mile (0.8 km). Originally used to access longwire radio radio antennas which were strung high above the Haʻikū Valley, between Honolulu and Kāne’ohe, they are closed to hikers.
  • The Florli stairs, in Lysefjorden, Norway, have 4,444 wooden steps which climb from sea level to 740 metres (2,428 feet). It is a maintenance stairway for the water pipeline to the old Florli hydro plant. The hydro plant is now closed down, and the stairs are open to the public.
