The walk from the river to the grotto goes through rain forest and is very scenic. the grotto itself is well worth visiting. i wish you could go inside the grotto, but due to the danger of a rock...

I have taken this "tour" so many times that I can practically do the talk story oh the way up and back. But, it is a great little outing for those that have never been, and for one reason or another I always end up having a good time. Just make sure and have bug spray or get some wipes... More

We went to the grotto by boat and walked along an easy path to the Fern Grotto. While at the site we had a local girl sing a song.

We cruised up the river to the grotto and were given a great explanation of the fern grotto plus several songs accompanied by ukuleles. Great relaxing time. You don't want to miss this.

Trip starts in a boat with roof listening and watching Hawaiian singers and dancers. Then we motored up the river, got out of the boat and walked up to the fern grotto. Not too long a walk and they don't rush the slow ones. Once at the grotto, we were given a little history followed by more live music. Our... More

On an island where every excursion is expensive it is refreshing to go on a tour packed with entertainment at such an affordable price. For approximately $50 our family enjoyed a boat ride filled with music, dancing, and hula lesson. There was a beautiful walk to the fern grotto and a great picture taking opportunity. Best money spent for and... More

This is a lovely boat ride with some historical information and some touristy entertainment. If you are adventurous a kayak tour may be more interesting

The Fern Grotto is a truly magical place and really Hawaiian. As part of a tour, we had a small cruise on the Wailua river, and then headed to the Fern Grotto. Along the way on the boat, we had a family which formed a band, and was wearing traditional Hawaiian costumes, who were playing typical music, whilst one of... More
