Kauai snorkeling is always an exciting adventure. We have snorkeled the whole island, and share below our favorite spots and boat trips.
What's the snorkeling like? There is free access to nearly every snorkel spot from beaches, as well as the opportunity to swim with big Green Sea Turtles and lots of fish in perfect depths. And in the summer, boat tours along the Na Pali Coast are wonderful. But make sure you read the safety cautions below because snorkeling on Kauai can be a little more dangerous than the other Hawaiian islands.

Na Pali Coast Tours
Kauai offers one of the most scenic snorkel boat tours in the world. You get to one of the best snorkel spots on the island and you see the iconic sheer green cliff scenery of the Na Pali Coast. And it can be a thrilling and harrowing boat trip out there and back. We have experienced Na Pali snorkel boat tours from the north and south sides of the island. In our eBook guide above we share more about what it is like, our preferred boat companies, what season to go and the most desirable place to start from.
Watching this Kauai snorkeling video is a great way for you to get a sense for what it is really like. It is from many locations around the island.
1. It's Always An Adventure
Snorkeling in Kauai always gets our blood pumping. To be honest, it does not offer the quantity or quality of snorkeling spots of say the Big Island or Maui, although we like it better than Oahu. But what it does offer is adventure, in a way that the other islands don't.
2. Natural Beauty In Abundance
There is no doubt that the natural beauty of this island adds to the enjoyment of the snorkeling. Around every corner, with each changing moment, Kauai is showing off it's good looks.
3. Free Snorkeling At World Class Beaches
We love to snorkel from beaches, at our own leisure. And Kauai delivers. Nearly all the snorkeling on Kauai is reached from shore.
4. Snorkel With BIG Sea Turtles
We always seem to find sea turtles on Kauai, and more often than not they are the biggest ones we have ever seen. With their large tails, and slow graceful swimming, these giants almost seem like dinosaurs.
5. Like Fish? No Problem
There are a handful of locations on Kauai where you can get up close and personal with a lot of fish, both on the north and south side of the island.
Strong Currents & Reef Cuts
Look at our Kauai snorkeling map below to see how all of the snorkel areas are on the south, north and east sides of the island. This is unlike Maui and the Big Island where most of the snorkel sites are on the more protected western side of the island. Since the spots are more exposed to the prevalent trade-winds and waves, stronger ocean currents are common in Kauai.
And while much of the snorkeling is behind fairly protective barrier reefs, the currents inside these areas flow out of cuts in the reef back out to sea. So you must be cautious not to be caught up in that outflow. For example, look at the picture of the very popular Ke’e Beach at right. Notice the big channel in front of the beach that is darker blue? The waves come over the shallower reef farther up the beach and all that water exits out that channel. If you have not yet read our safety tips page about currents you can here.
Long & Steep Hikes
Kauai is a mountainous island, and the way you get to a handful of the better snorkeling beaches is by hiking down (and back up) some steep and often slippery and long trails.
Planning Your Trip Around Kauai Rain & Seasons
Kauai is so beautiful because it is one of the rainiest places on earth. But as you can imagine all that rain can impact your snorkeling. Many times we have hiked to a beach in the rain, or had a torrential rain squall and winds suddenly come across us in the water. So staying flexible with your plans is essential for a fun Kauai snorkeling trip. Read our Kauai snorkeling accommodations page for tips on the sunnier and rainier areas to stay for snorkeling.
Because a lot of the snorkeling on Kauai is located on the north shore, it is often inaccessible in winter. It is affected by the same north swell that makes Oahu a surfing mecca in the winter. You may find it useful to read our When To Snorkel Hawaii page to help you plan your trip for when the conditions are best for snorkeling, usually in the summer.
