Twin Waterslides & Snorkeling off Kauai's Steepest Sea Cliffs

You board a luxury catamaran at Kauai's dock and spend the day cruising the Na Pali Coast's sea cliffs and hidden coves. Snorkel in clear water, slide down the boat's twin waterslides, spot sea turtles and monk seals, and eat lunch while the open bar runs. The crew handles safety and instruction; you handle getting wet and enjoying the view. Bring sunscreen and a swimsuit — plan to be in the water most of the afternoon.

The Experience

The dual engines of the Lady Kailani hum as you step aboard a 65-foot catamaran built for the kind of comfort most boats don't bother with — padded seating on every deck, shaded lounges, a walk-up bar, and a shaded helm lounge where you can actually sit next to the captain if you want. The boat leaves the dock and heads straight for the Na Pali Coast, where the cliffs rise so fast and so high that waterfalls still run down them even in dry season. You're looking at 360 degrees of ocean from wherever you stand, and the crew — a USCG-licensed captain plus three others trained in water safety — keeps things moving without any of the rushed feeling you get on packed tour boats.

Once you reach the snorkel site, the water entry is from the boat's swim platform or straight off the deck, and the crew hands you snorkel gear and points out where the sea turtles and monk seals usually hang. If you want something louder, there are two waterslides built into the boat itself — they're the kind of thing you don't expect on a catamaran, and they change the whole vibe from "nature documentary" to "actually having fun." Between water time, the bar opens and lunch gets served. The open bar runs to Mai Tais and beer for adults, soft drinks for everyone else. Fresh baked goods and seasonal fruit come out in the morning, and the meal after swimming is substantial enough that you're not hunting for dinner later. Winter months bring humpback whales close enough to see without binoculars; summer is better for dolphins and flying fish, though you're never guaranteed anything — ocean conditions drive what shows up.

The boat can hold up to 49 people, but it doesn't feel crowded because the decks are genuinely spacious and there are two full restrooms onboard, plus outdoor freshwater showers so you can rinse off the salt before heading back. The whole experience runs on the assumption that you came to be on the water, not to squeeze into a cabin or stand in a line. Routes can shift if the north shore gets rough — sometimes the crew reroutes to the south coast instead — so flexibility matters more than a fixed itinerary. Bring a swimsuit, sunscreen, sunglasses, and a hat; the tour is barefoot unless you have a medical reason for shoes. A light rain jacket and a towel are worth packing, and if you're prone to seasickness, talk to a doctor before the day because the ocean doesn't always stay flat.

Is this one for you?Book this if you want the Na Pali Coast without the crowded tour-boat feeling — the 65-foot catamaran's size and amenities mean you're not fighting for deck space or waiting in line for the bar, and the waterslides turn it into something more than just a snorkel trip. Moderate fitness and comfort with rough water are required; if you're prone to seasickness or have joint or mobility concerns, this isn't the right fit.
