Fern GrottoExplore > United States > Kauai > Fern Grotto
For and unusual Hawaii adventure, cruise up the Wailua River to a lava rock grotto covered with tropical ferns. At the grotto, you will be serenaded by Hawaiian musicians playing traditional, local songs. The acoustics within this natural amphitheater are fanatastic and greatly enhance the singing and guitar accompaniment. The trip up this historic and sacred river takes about 40 minutes via a long flat bottom riverboat. Boats depart from the south side of the river every 30 minutes. The Wailua River is the only navigable river in Hawaii and, along with the cruise boats, kayakers, motor boats and water skiers "go with the flow". On the way to the Fern Grotto, you will encounter numerous photo opportunities of the tropical gasslands lining the river and cloud-capped Mt. Waialeale looming in the background.
Take Highway 56 north toward Wailua. Cruise boats and kayak rentals are located on the south side of the Wailua River (before crossing the bridge).
