#13 of 31 in Nature in Kauai
Cave · Nature / Park
Surround yourself with some of the most beautiful nature the island of Kauai has to offer by visiting Fern Grotto. The lush lava-rock grotto is one of the island's natural wonders--a natural amphitheater renowned for its acoustics, it's considered one of the most romantic locations in the whole of Hawaii. The only way for visitors to reach the sight is by taking a boat on the Wailua River. There are numerous companies that organize river cruises, while the more athletic visitors can also kayak to the grotto. For safety reasons, entering the grotto itself is prohibited, but there is a viewing platform from where you can admire the sights and sounds.

  • The Riverboat ride was very relaxing soothing to the soul in a little hike towards the fern Grotto was exceptionally interesting with all kinds of foliage and tropical flowers.

  • Really cool place but twisted my ankle there. Careful where you step. But loved it there.
