Wailua - Fern Grotto

Wailua's greatest attraction is Fern Grotto, which extends along the 3 miles/5km river to its source and can be reached by boat. Boats depart from Waialua Marina.

The grotto is an enormous amphitheatre made of rock in which, thanks to the constantly-damp atmosphere, conditions are ideal for bracken to grow. It is also a popular place for weddings - they take place here almost daily. The boat's crew sing a Hawaiian wedding song for tourists while a commentary is given over a megaphone.
