Fern Grotto is a other great outdoors located in United States.
Hawaii United States
Nice 90 min river tour up the river here. History of it told. Nice live singing and dancing too!
Was an awesome side trip before the luau, the grotto is very cool and the crew of the boat was very informative and entertaining.
Historically, it's a popular spot to get married
Lots of Mosquitos so bring Off (bug spray) :)
Too bad you can't go into the caves anymore (closed 4 yrs ago when rocks started to fall)
Nice relaxing 90 min tour up the river to the grotto. Once there walked to it, history and live singing and dancing for us. Nice Hawaiian songs on way back from the guides/staff was a treat. - Deborah Lazaroff
Tried the tubing adventure. Perfect for all skill levels. They provide gloves and helmet for safety and we brought water shoes. Lunch of fresh sandwiches, chips and a cookie was a nice treat. - Candace E-J
Look into the valley at what would have been the local bread basket feeding the local area - ???????????????????????????? ????????????????????????
Great food, good service. Very nice place, better than the ones at the hotels. - John Dailey
So beautiful! You can swim in the pool below, and even stand under the waterfall itself. Worth the hike and paddle to get there. - Jeff Martens
