Snorkeling tours in Kauai that follow the Na Pali Coast all run the same route: past a stretch of sea caves, then to a reef site the captain chooses that morning based on ocean conditions. The caves and the reef stop are not the same thing. Mixing them up is the most common misunderstanding first-time visitors have about what these tours do.
Here’s how the route breaks down, cave by cave and reef by reef, so you know what you’re seeing and where.
Where the Route Runs: From Kikiaola Harbor to the Reef
Every standard tour departs Kikiaola Small Boat Harbor in Kekaha, on the west side of Kauai, the closest departure point to the Na Pali Coast.
From Kikiaola, the route runs along the Polihale shoreline, past the waterfalls at Kalalau Valley, and through the sea cave stretch of the coast. A roughly one-hour snorkel stop comes next, before the return trip.
A full tour runs 4.5 to 5 hours, and being closer to the coast means more of that time is spent on the water instead of getting there. Our Na Pali Coast tours page has the current departure schedule if you’re comparing tour times.
The Sea Caves You’ll Pass: Pirates Cave, Rainbow Falls, and Honopū Arch
Three named formations make up the cave stretch of the coast: Pirates Cave (Waiahuakua in Hawaiian), Rainbow Falls, and Honopū Arch.
Pirates Cave and Rainbow Falls are enclosed, with a single opening at water level where a boat can nose inside when conditions cooperate. Honopū Arch is different: an open natural arch, not an enclosed cave, connecting two beaches that have no road or trail access. Film crews have returned to it for King Kong, Six Days Seven Nights, James Bond, and Pirates of the Caribbean. All three sit along a stretch of coast reachable only by water.
Can You Swim Inside the Sea Caves?
No, snorkeling does not happen inside the sea caves. Entering Pirates Cave or Rainbow Falls is part of the scenic route: the boat noses into the cave mouth, holds position briefly, and backs out, as long as ocean conditions allow that day. It’s a sightseeing pass, not a place where guests get in the water.
The same swell and surge that decide whether a cave is enterable also make the cave interior unsuitable as a stop; a boat moving through a narrow opening on live water needs to keep moving, not sit still with guests over the side.
The snorkel stop is a separate part of the tour entirely, at a reef site away from the caves. The captain picks that site based on conditions, the boat anchors, and guests spend about an hour there with masks on. If time with fish and coral is the goal, that happens at the reef stop, not at the caves.
A Map of the Reef Stops: Makole, Ke’e Beach, and Nualolo Kai
The captain chooses the day’s snorkel stop from three reef sites, and which one you get depends on conditions that morning. Nualolo Kai sits further up the Na Pali Coast with no road or trail reaching it directly; a boat is the only way in, which keeps it away from beach foot traffic.
Ke’e Beach, also called Tunnels, sits at the end of the road on the North Shore near Haena and is reachable on land. Even so, the reef structure offshore is part of the same rotation, drawn into the mix when Na Pali conditions favor a site closer to that end of the coast.
Makole is the third option along the route, a reef stop used when it’s the site the water favors that day.
Swell direction, wind, and visibility are what the crew weighs each morning before making that call.
What You Might See at the Reef Stop
Honu, the Hawaiian green sea turtles, are commonly seen resting near the reef or surfacing to breathe, though never guaranteed. Spinner dolphins and Pacific bottlenose dolphins turn up often along the Na Pali route on the way to and from the reef stop.
Our captains know the tides and the places dolphins tend to travel, so it’s rare that a morning goes by without a sighting. Still, the ocean decides, not the schedule. Reef fish and coral fill the water at whichever site the captain selects that day.
What’s Included at the Snorkel Stop
Every snorkel stop includes the same core inclusions:
- Snorkel gear and flotation devices. Provided for every guest, fitted before anyone gets in the water.
- Staying aboard. Guests who’d rather not snorkel can stay on the boat while it’s anchored.
- Lunch. A deli-style spread of turkey, ham, roast beef, or vegetarian, with fruit, snacks, soft drinks, and local juices, served after the cave stretch, before or around the snorkel stop, depending on timing that day.
- Alcohol. Not served on board. Guests may bring their own, sealed until after the snorkel stop.
Boat choice affects the experience more than most guests expect going in. Smaller boats sit closer to the water and turn tighter through the cave stretch. The Na Pali Kai III’s 360-degree walk-around deck gives photographers a clear view of the reef stop from multiple angles. Our boats page breaks down capacity and age minimums by boat if you’re deciding which fits your group.

Makana, the Hawaiian word for gift, is the name our family put on these tours, but the history behind them runs longer: over 200 years navigating this same stretch of coast, caves,s and reefs included.

Frequently Asked Questions About Snorkeling Tours on Kauai’s North Shore
Can you swim inside the Na Pali Coast sea caves?
No. The boat may enter or approach the sea caves as part of the scenic route when ocean conditions allow, but that’s a sightseeing pass, not a stop where guests get in the water. Snorkeling happens separately, at a reef site away from the caves.
Which reef site will I snorkel at: Makole, or Nualolo Kai?
It depends on the day. The captain selects among Makole and Nualolo Kai based on ocean conditions that morning, and the choice isn’t confirmed until the day of the tour.
Is snorkeling included in every Na Pali Coast tour?
Yes. Every standard tour includes a snorkel stop of about one hour, along with snorkel gear and flotation devices. Guests who prefer not to enter the water are welcome to stay aboard while the boat is anchored.
Are dolphins or sea turtles guaranteed on the tour?
No, wildlife sightings are never guaranteed since these are wild animals moving through open water. Spinner dolphins, Pacific bottlenose dolphins, and honu are commonly seen along the route, and our captains’ knowledge of the tides makes sightings likely, but never certain.
How long is the snorkel stop, and can beginners do it?
The snorkel stop runs about one hour, and beginners are welcome. Gear and flotation devices are fitted before anyone enters the water, and guests who’d rather watch from the boat can stay aboard for the full stop.
