If thats where I am thinking of, it used to be called the stairway to heaven hike. Beautiful but you had to sneak into the hike to do it or local police would arrest you. A few of us in the Navy Reserves at the time managed to hike in unobserved and climb the cliff overlooking Kāne‘ohe Bay. The trail was there because there used to be a LORAN station at the top decades ago.
Not sure if access is allowed today or not.
Nope. Not the stairway.
