Lovely spot - local Hawaiian feel - In 2013, I sat at a picnic table while my husband snorkeled.A gentleman was burying a coconut and I said hello. He said it would make nice shade some day and asked where we were from. He introduced himself as John Lydgate and that he looked after the beach and organized clean ups. Meeting him was a highlight of our visit to the islands! Mahalo
Sign should be acurate - The Falls were great. However, as a public park the information you forward should be accurate. The picture of Niagara Falls that you show, is in Ontario, Canada and not in New York.
Bring comfy shoes - This is one of the neatest places that I have every been, but bring comfortable shoes as there is much to see and do, The day we went lava was flowing but it was a 8 mile hike to see it, sadly we were not prepared. Check with the rangers when you arrive they are a wealth of information.
