This activity should be discontinued

The fern grotto is a piece of Hawaiian history. Originally the site of a huge waterfall, before the river was diverted for irrigation, and originally the site of hundreds of ferns, before being battered by cyclones, this place is not what it once was.
It would have been a very impressive tourist attraction in the early 1900s but unfortunately ferns need water to grow and as it is with the river not going through here this place will never be as impressive and at the moment the tourist operators are trying to flog a dead horse.
Unless they divert the river back through here and let the ferns regenerate I would not recommend it. Time to put this activity out to pasture!
