75+ Years of Aloha on the Banks of the Wailua River
A Place Unlike Any Other
Fern Grotto Inn has a long and unique history — one that other vacation rental properties simply can't tell. We have been in business for 75+ years. All 9 of our cottages and homes were originally built in the 1940s and 1950s. While they've all since been renovated, most recently in 2021, they retain their original materials and historic touches.
Come visit us at Fern Grotto Inn to take part in our unique history here in remarkable Kauai. We hope to see you soon!
"While some things have certainly changed at Fern Grotto Inn, the land and cottages themselves retain their storied past and look forward to a bright future."— Paul, Proprietor · Fern Grotto Inn
How It All Began
Ohana House was the first property to call these lush grounds home. Originally built in 1942 using lumber from dismantled supply ships during WWII, the Ohana House was constructed for a Japanese widow and her two children.
During the construction of her home, due to a heightened paranoia towards Japanese-Americans, the widow and her children were sent to an internment camp to wait out the rest of the war. A painful chapter of American history, written into the very walls of the Ohana House.
After the war ended, she was welcomed to her new home — now called the Ohana House. A few decades later, her son became the Chief of Police of Kauai, a remarkable chapter in the story of this property.
Seeing the undeniable beauty and business opportunity of her incredible slice of Kauai, she began building the other properties you now see at Fern Grotto Inn and renting them out as transient vacation rentals.
All 9 cottages were renovated most recently in 2021 — updated with air conditioning, modern kitchens, and fresh interiors, while preserving the original plantation-era character and materials that make Fern Grotto Inn truly one-of-a-kind.
Fern Grotto Inn continues to welcome guests from around the world, earning 1,000+ five-star reviews on Google, Airbnb, and TripAdvisor. 75 years in, the story is still being written.
Our Property
In our sun-drenched cottages, you could spend your entire vacation relaxing in the fresh, island-inspired interiors. But with a tropical oasis as your private yard, you'll want to spend just as much time outside. Fire up the gas grill, paddle the Wailua River, or take a bike out on the 10-mile Kauai coastal path — all from your doorstep.
What We Stand For
We've preserved the original character of these 1940s plantation cottages — real history, real materials, real Kauai. Not a resort replica.
Our proprietor Paul is always just a phone call away. We're a small, personal operation — not a faceless property management company.
The lush tropical grounds of Fern Grotto Inn have been tended with love for over 75 years. We take care of Kauai's natural beauty.
Kayaks, paddleboards, bikes, snorkeling gear, beach chairs — all complimentary. We want you exploring Kauai, not paying for equipment.
Come Stay With Us
We have 9 unique cottages waiting for you — from the historic Ohana House to cozy studio retreats. All on the banks of the Wailua River, one block from the beach.
