Correct, just north of Honolulu.Sometimes confused with neighbouring Koko Head (including by me). A strenuous and steep climb up 1048 old WW2 incline railway ties, many disintegrating, often spaced a long way apart and uncomfortably high. Took me about an hour to ascend the 1 km or so. Highly recommended mini adventure significantly more challenging than the ever popular Diamond Head, which I had revisited a couple of days earlier. All yours wobbly.
