With a friendly guide and the convenience of pickup from Nawiliwili Harbor, it’s an experience designed for travelers who want a taste of authentic Kauai, minus the hassle.
What makes this tour special? First, the scenic boat ride down the Wailua River offers views of cascading waterfalls like Opaekaa Falls and the iconic Wailua Falls.

What to Expect from This Kauai Shore Excursion
When your cruise ship docks at Nawiliwili Harbor, this tour offers a seamless way to explore some of Kauai’s most iconic sights with minimal hassle. The air-conditioned coach will pick you up at the pier, making the transition from port to adventure smooth and comfortable. The guide, often praised for being friendly and knowledgeable, will set the tone for a relaxed yet informative experience.
The Drive to Wailua River
The journey begins with a short drive through Kauai’s beautiful countryside, heading towards Waimea and the lush landscapes that define the island’s eastern side. One reviewer highlighted the “beautiful flowers and trees” en route, which really sets the scene for a tropical escape. The red volcanic terrain and verdant valleys give a sense of Kauai’s volcanic origins and fertile landscape.
Stop at Opaekaa Falls
The first notable stop is Opaekaa Falls, a 151-foot waterfall spilling into a hidden pool. It’s a perfect photo opportunity, and despite being a quick 20-minute stop, it leaves many guests with lasting impressions. The free admission makes it a worthwhile peek into Kauai’s waterfall wonderland. One reviewer called it a “spectacular” sight, noting how the falls added to the overall sense of lushness.
The Wailua River Cruise
The main event is the boat cruise down the Wailua River, often described as “mellow”, “easy going”, and “very relaxing”. The boats are typically large and stable, ideal for a tranquil ride. The passengers are serenaded by Hawaiian songs performed live on the boat, creating an authentic atmosphere. Several reviews mention how the music and hula dance at the Grotto enhance the experience, making it not just a sightseeing trip but a culture.
The views during the cruise include Wailua Falls, a double cascade that’s often called the “Niagara of Kauai,” and the more secluded Opaekaa Falls from a different vantage point. The passive boat ride allows for plenty of photo opportunities, with many reviewers noting how “the scenery was spectacular” even if the weather was partly rainy or cloudy.
The Fern Grotto Experience
After the cruise, you’ll disembark for a guided walk to the Fern Grotto, a tropical rain forest filled with native plants and ferns. The grotto itself is a natural amphitheater, and the serenade by Hawaiian performers adds to its charm, often described as “beautiful” and “memorable” by travelers.
While some reviewers wished they could have entered the grotto, safety considerations prevent full access—that’s a reminder that natural settings often come with restrictions but also preserve the authenticity. The walk to the grotto is generally short and easy, making it accessible for most.
Additional Cultural Highlights
The guide often shares stories about Kauai’s history, the sacred significance of the river and grotto, and the royalty associated with this landscape. Some reviews mention learning a hula dance or hearing local Hawaiian music, which adds a lively, educational component to the trip.
Value and Considerations
At $109, this tour offers a balanced mix of natural beauty and cultural insight. It’s priced to include port pickup and drop-off, which saves you from navigating transportation on your own. The small group size (maximum 24 travelers) ensures a more intimate experience, with plenty of chances to ask questions or take photos.
However, the weather can influence your enjoyment—rains are common in Kauai, and while the boats are stable, a downpour might limit visibility or comfort. One guest noted that the river cruise and grotto visit could be affected by weather, so it’s wise to check the forecast.
Authenticity and Guest Feedback
The reviews paint a picture of a pleasant, well-organized trip with highlights like friendly guides, stunning scenery, and entertaining Hawaiian music. Many guests describe it as “easygoing” and “a must-see” for first-time visitors. Some, however, found the schedule tight or were slightly disappointed that they couldn’t enter the grotto itself.
A notable point is that most reviews are highly positive, with several praising the knowledgeable guides and beautiful scenery. One guest even called it “Hawaiian heaven”, capturing the overall vibe.
