Kauai Northeast Coast Explorer: Fern Grotto River Cruise, Waterfalls & Kilauea Lighthouse
Float up the Wailua River to a fern-draped grotto, then loop the north shore for waterfalls, Hanalei Bay views and the century-old Kilauea Lighthouse. This six-hour tour packs Kauai’s east‑coast highlights into a single, well-paced day.
The Experience
Before You Go
Book morning pickups
Morning departures mean calmer waterways and softer light for photos; confirm your pickup time 24 hours in advance.
Bring reef-safe sunscreen
You’ll be outdoors for most of the day—use reef-safe sunscreen to protect coral and your skin.
Wear grippy shoes
Paths at the grotto and short lookout trails can be uneven and damp—light hiking shoes or sturdy sandals are best.
Motion-sickness prep
If you’re sensitive, take meds before boarding and choose a mid-boat seat for a steadier ride.

Conservation Note
Visitors are asked to stay on marked paths, use reef-safe sunscreen, and avoid disturbing nesting seabirds at Kilauea to support ongoing restoration efforts.
The Wailua River corridor was once a political and ceremonial center for Hawaiian chiefs; taro cultivation and ancient heiau (temples) shaped the valley.
