Fern Grotto, Wailua, Kauai
Fern Grotto is a fern-covered, lava rock grotto located on the Wailua River on the eastern side of Kauai.
Access to the Grotto is by boat on the Wailua River as part of the Wailua River State Park. Tour boats ply the waters of the park and the Grotto has long been a popular stop on the tour. Fern Grotto was nearly destroyed when the island of Kauai was hit by hurricane Iniki in 1992. Most of the ferns hanging from the grotto were torn from the rocks and, though much of the plant life has rebounded, the grotto has yet to recover much of the grandeur for which it was previously known. In spite of the damage, it remains one of the most popular and beautiful spots on the island.
