Fern Grotto Tours and Activities
Kauai’s Fern Grotto is a fern-covered lava cave on the south fork of the Wailua River. Once off-limits to all but Hawaiian royalty, the Fern Grotto is now accessible to visitors, but only by boat. The grotto acts like an amphitheatre, and musicians are drawn to the site for its incredible natural acoustics.
