While the Fern Grotto may be "overrated", the trip TO the Fern Grotto IS the part to enjoy.We all emptied out of our tour bus and got in the red and white boat (as distinguished from the other boat which belonged to the second tour company on the river). As we were waiting for other passengers who paid $15 for only this portion of the tour, we decided where we wanted to sit. It really didn’t matter since the boat wasn’t full and all the seats were good. Then we began chugging down the Wailua River, the largest "navigatable" river in Kauai and the entertainment began. During the trip down the Wailua River, one of the two male "hosts" drove the boat while the other kept up a running commentary of history of the river, the people, and other interesting tidbits of information. Then they would switch roles. Both of the hosts were funny as well as informative. I wish I could remember some of their jokes but then that would spoil it for when you go! Actually, since we had our video cam, I do have some of the jokes, and other antics, recorded!
After at least 10 minutes we docked where we were told to follow the road to the Fern Grotto. More jokes followed (along the line about not getting lost as if you could). We all sat in the "amphitheater", which was rock seats overlooking the performing area. Then the one woman began dancing the hula while the other woman began singing and the two men sang and also played the guitar. All three had beautiful voices. While listening (and one claim to fame of the area is the great acoustics), we also looked around at the beauty of the place. It definitely wasn’t as spectacular as Howes Caves (near where I live), but it definitely had charm and beauty. During this time we all were put in the mood of imagining having a wedding at the Fern Grotto (I mentioned to my husband that we should return in two years and renew our vows as we celebrate our 35th wedding anniversary). The only negative about having a wedding there is paying accommodations and travel for all of the guests!
Returning down the river was even better. Again the men told jokes and stories and the women danced and sang. In addition, the one male was dancing as he was driving! At this point I am glad I have the video! In addition, the crew got everyone on board the boat to stand up and they taught us a basic hula. Corny but fun. All too soon it was over.
One note of caution: it is better to have proper footwear since there is some moderate hiking involved and some of the ground is wet.
