Fern Grotto

Kauai Hawaii Vacation Guide

The Fern Grotto is a popular tourist destination located on the Wailua River in East Kauai.  It is a massive lava tube filled with ferns.

Located just north of Lihue, it can be accessed only by boat.  Barges sail from the marina up the river for a distance of about two miles. A paved pathway then leads through some lush foliage into the cave.
