Make a Iao valley state park teservation & payment IN PRIOR! No mobil signal in that area. After the short walk up to the Overview and fown to the steam, the walk will change to a hike - very rocky and narrow. Not sure if i recommend this spot for this money, i guess you can get similar view from the Kepaniwal Park (short begore on tje road)
