Exploring Kauai’s Underwater and Coastal Wonders: A Full Day of Scuba and Scenic Beauty
If you’re considering a full-day adventure that combines the thrill of scuba diving with the awe-inspiring scenery of Kauai’s Na Pali Coast, this full-day scuba tour off the Na Pali Coast at Mana Crack might just be what you’re looking for. While I haven’t personally done this tour, I’ve researched it thoroughly and can tell you it offers a fascinating blend of underwater exploration and scenic coastline views.
What really draws me to this experience are the chance to see large marine creatures like barracuda and reef sharks in crystal-clear water and the opportunity to explore the Na Pali Coast’s famous sea caves and waterfalls from a unique perspective. Plus, the fact that it’s a guided adventure with all equipment included makes it quite accessible.
One thing to keep in mind is that this tour is only for certified divers with at least 15 dives under your belt— it’s not a beginner-friendly trip. Also, the early start time at 6:30 a.m. might seem a bit daunting, but it’s necessary to beat the wind and get the best conditions. Overall, if you’re an experienced diver eager to combine underwater marvels with scenic sightseeing, this could be a perfect fit.
Key Points:
- Primarily for certified divers with at least 15 dives, so not ideal for beginners.
- Two dives at different Mana Crack sites offer varied underwater experiences, with depths from 45-100 feet.
- Includes a scenic tour of the Na Pali Coast with opportunities for sea caves, waterfalls, and possibly dolphins and whales.
- All equipment, snacks, and lunch are included, making it a convenient full-package experience.
- Weather-dependent, with rerouting options and a 45% discount if conditions aren’t suitable.
- Small group size (up to 6 travelers) means more personalized attention and fewer crowds.
An Honest Breakdown of the Kauai Mana Crack and Na Pali Coast Experience

Getting There and Starting Out
The adventure begins early — meet at Kikiaola Small Boat Harbor at 6:30 a.m. — which might feel a bit early, but it’s a smart move to avoid wind and rough seas later in the day. From there, you’ll take a roughly 30-40 minute boat ride to the starting point of your first dive. This initial trip alone is part of what makes this tour special, as it sets the scene for a day packed with stunning scenery and marine life.
The First Dive at Mana Crack
Once you arrive at Mana Crack, the furthest offshore reef in Hawaii, you’ll start with a deep drift dive between 50-100 feet. The site is renowned for its exceptional visibility and unique topography, offering a chance to see large fish like barracuda and spotted eagle rays. This dive is described as fast-paced and strenuous, so it’s best suited for experienced divers comfortable with longer or more challenging dives.
Why this site is special: Mana Crack is an 11-mile-long sunken barrier reef dotted with various drop points, which means you’ll likely explore different sections during your dives. Multiple reviewers mention the amazing marine life — from white tip reef sharks to rainbow runners — making it a real highlight for underwater enthusiasts.
The Surface Interval and Scenic Na Pali Coast Tour
After the first dive, you’ll take a break — enjoying snacks and drinks — and then hop aboard to cruise along the Na Pali Coast, one of the most dramatic coastlines in Hawaii. This stretch of the coastline is famous for its towering cliffs, waterfalls, sea caves, and lava tubes. The tour promises close encounters with waterfalls, sea caves, and possibly spinner dolphins and humpback whales in winter.
What makes this part stand out: The Na Pali Coast tour is a highlight that appeals even to those who might not be divers. The scenery is breathtaking and offers countless photo opportunities. Exploring sea caves and lava tubes provides a sense of adventure, and the chance to see marine mammals adds a special touch.
The Second Dive
After the coast tour, you’ll return to your second dive at a different site on Mana Crack, usually shallower (45-80 feet) and at a different drop point. The variety in locations means you might encounter different marine life and topography, keeping the experience fresh.
What to Expect from the Dive: Expect to see more colorful fish like stripe belly puffers, black surgeonfish, and wringtail wrasse, adding to the vibrant reef life. The divers I researched note that these sites are often miles apart, offering a sense of exploration and discovery.
Logistics and Practicalities
The tour lasts about 8 hours, ending back at the dock around 2 p.m., giving you plenty of time later in the day to relax or explore more of Kauai. The price of $650 per person is on the higher side, but considering the inclusion of all equipment, snacks, and lunch, it’s a fair value for an all-day guided adventure.
Weather and Flexibility: If weather conditions are unfavorable, the tour will be rerouted to the south side of Kauai, with a 45% discount offered. This flexibility is reassuring, as it means your experience is protected from minor weather hiccups.

What This Experience Means for You

This tour is well-suited for experienced divers who want to see some of Hawaii’s most impressive underwater environments and enjoy a scenic journey along the Na Pali Coast. Its small group size (maximum of six travelers) ensures personalized attention and a more intimate experience. The combination of two dives and a coast tour provides a well-rounded day that mixes adrenaline, exploration, and stunning views.
However, given the early start and strenuous nature of the dives, it’s not ideal for casual snorkelers or those new to diving. Plus, the reliance on weather means you might need to be flexible with your plans.
Final Thoughts: Is This Tour Right for You?
If you’re an experienced diver craving a full day of marine adventure combined with one of Hawaii’s most iconic coastlines, this tour offers a compelling package. The opportunity to explore Mana Crack’s remarkable reef and then drift along the rugged Na Pali Coast makes for a memorable day—especially if you’re comfortable with challenging dives.
The fit is perfect for travelers who love marine life, scenic boat rides, and don’t mind an early start. The inclusion of all equipment and food makes it convenient, but the high cost reflects the specialized nature and exclusivity of the experience.
For those who want a balance of underwater excitement and awe-inspiring scenery, this might just be one of the most fulfilling ways to experience Kauai’s natural beauty.
