Wailua River & Fern Grotto

Flowing from the crater of Mount Waialeale and meandering on its way to the Pacific, the Wailua River is sacred to Native Hawaiians. The area was once kapu (taboo) for anyone to enter except for royalty. Nowadays kayakers can paddle down the river and then hike over to Secret Falls, and a river cruise excursion with Smith’s Family Kauai—a local family that has been running the tour for generations—will take you to Fern Grotto, a natural lava rock amphitheatre draped in a curtain of tropical ferns, on their open-air boat.
