If you’re headed to the Big Island of Hawaii and your crew loves marine life, clear blue water, and a bit of outdoor history, then Honaunau Bay—also called “Two Step”—deserves a top spot on your must-do list. Located about 22 miles south of Kailua-Kona, this unique bay offers an unforgettable underwater experience for families with older kids and confident swimmers. It’s also nestled beside one of Hawaii’s most fascinating historic sites, Puʻuhonua o Hōnaunau National Historical Park.

What’s So Special About “Two Step”?
The nickname “Two Step” comes from the natural lava rock ledges that act like stairs into the bay. They’re your gateway into one of the best snorkeling spots on the Big Island. It’s not your typical sandy beach entrance—here, you’ll navigate lava rocks and time your entrance with the waves. It’s adventurous and incredibly rewarding once you’re in the water. The reef is teeming with tropical fish, sea turtles, and even the occasional pod of Hawaiian spinner dolphins (though it’s illegal to swim directly toward them—look, don’t chase!).
What Parents Should Know
Let’s get the logistics out of the way—this is not a beginner’s beach day. Two Step is best for intermediate to advanced snorkelers, especially because of the rocky entrance, occasional strong currents, and lack of lifeguards. However, older kids who are confident swimmers (and enjoy a little adventure) will absolutely love it.
There are no lifeguards, and only basic facilities like portapotties are available nearby—so plan accordingly! There are no showers, no snack bars, and no beach umbrellas to rent. It’s all about nature, snorkeling, and soaking up Hawaiian history.
If you’re visiting with younger kids or anyone who won’t be snorkeling, there’s still fun to be had. Just a short stroll away is Puʻuhonua o Hōnaunau National Historical Park—a beautifully preserved cultural site where families can walk among ancient temples, royal fishponds, and sacred spaces. This was a real-life place of refuge in ancient times, where Hawaiians could find safety if they broke sacred laws. Kids love learning the legends, exploring the lava rock structures, and imagining life in ancient Hawaii.
Tips for a Safe & Fun Visit
1. Getting In the Water
You’ll enter the water near the center of the bay from those famous lava “steps.” Wait until a wave pulls back before sliding in—that’s your cue. The water here starts out about 6–10 feet deep and becomes deeper the farther you swim out.
2. Where to Snorkel
Swim to the left side of the bay for deeper waters (up to 20 feet), vibrant reef structures, and the best chance of spotting sea turtles. On the right side, you’ll find a shallower reef and unique underwater topography. Keep your eyes peeled for schools of bright yellow tang, parrotfish with their beak-like mouths, and even long trumpetfish trying to blend in.
3. Stay Safe Around Wildlife
If you’re lucky enough to spot dolphins, enjoy them from a distance. Hawaiian spinner dolphins rest during the day, so let them cruise by without disturbance. And if you see sea turtles (you probably will!), be sure to give them at least 30 feet of space.
4. Tide Pools and Easy Exploration
Not everyone in your group wants to snorkel? No problem! Near the boat launch area, there are shallow tide pools and a small beach-like area that’s perfect for kids to wade and explore. Crabs, tiny fish, and other sea critters hide among the rocks here, offering a gentle introduction to marine life without getting fully submerged.
Bonus: Add Some Culture to Your Day
The Puʻuhonua o Hōnaunau park is more than just a scenic backdrop—it’s a fascinating part of Hawaiian heritage. Wander through the grounds to see carved wooden statues (ki‘i), replica canoes, and preserved structures that tell stories of kings, warriors, and sacred Hawaiian traditions. It’s a great place to take a break from the sun and add some educational value to your trip.
Honaunau Bay’s “Two Step” snorkeling is pure magic, especially for families with older children who are ready to explore Hawaii’s wild side. It’s raw, real, and incredibly beautiful. While it’s not the easiest place to snorkel with little ones, the nearby tide pools, historical park, and abundant sea life make it a memorable experience for everyone.
Pack reef-safe sunscreen, sturdy water shoes, and plenty of water and snacks—and don’t forget your snorkel gear! Add it to your family’s Big Island itinerary and get ready for a snorkeling adventure you’ll be talking about long after the trip is over.
