Located on the sun-drenched south Kona coast of the Big Island, Honaunau Bay, commonly known as Two Step, offers one of the most rewarding snorkeling experiences in all of Hawaii. This spot combines exceptionally clear waters, easy ocean access, and thriving marine biodiversity, making it a standout destination for both first-time snorkelers and seasoned underwater explorers. The bay is a haven for green sea turtles, which are frequently spotted gliding gracefully over the reef or resting on the rocky sea floor. These gentle creatures, protected by law and respected in Hawaiian culture, are just one part of the magic you’ll encounter here.
Framed by dramatic lava rock and backed by lush greenery, Two Step is not only beautiful but also incredibly accessible. Unlike other snorkeling spots that require long swims or boat rides, here you can step directly into the ocean from a lava ledge that gives the site its nickname. Within moments, you’re surrounded by colorful coral, schools of reef fish, and the peaceful rhythm of the Pacific. Whether you’re snorkeling, free diving, or simply floating and soaking in the view, Honaunau Bay delivers a deep sense of connection to Hawaii’s natural world.
Why It’s Called “Two Step”?
The name “Two Step” comes from the unique lava rock formation at the shoreline, where two flat, submerged ledges create a natural staircase into the ocean. These “steps” make it remarkably easy to enter and exit the water without the need for sandy beaches or cumbersome gear. It’s this simple, intuitive access that has made Two Step especially popular among first-time snorkelers, families with kids, and even older visitors who may be hesitant about navigating slippery rocks or rough surf.
Unlike many other snorkeling locations where entry can be awkward or even dangerous during high surf, Two Step generally offers calm, protected conditions, especially in the morning. Just a couple of careful steps down the lava ledge and you’re immersed in warm, crystal-clear water, ready to explore the underwater reef system that begins just a few feet from shore. For those unsure about deep-water swimming, the shallow reef zone near the steps allows you to stay close to shore while still experiencing an incredible variety of marine life. It’s an effortless gateway to one of Hawaii’s most vibrant marine ecosystems.
What You’ll See While Snorkeling
Two Step is celebrated for its calm waters and consistently excellent visibility, making it a favorite spot for snorkelers of all experience levels. The underwater landscape here is both vibrant and dynamic, with a living reef that begins just yards from the shore and extends into deeper waters for more advanced exploration.
One of the main attractions is the colorful coral reef, which supports a wide variety of tropical fish. As you float effortlessly above the reef, you’ll likely spot butterflyfish weaving between coral heads, angelfish gliding in and out of crevices, and parrotfish crunching away at the coral with their beak-like mouths. The abundance of marine life here is a testament to the health of the reef and the bay’s protected status.
But the real stars of the show are the Hawaiian green sea turtles, or honu, which are frequently seen grazing on algae-covered rocks or resting serenely on the sandy patches between coral formations. These gentle creatures often come remarkably close, giving you the chance to observe them in their natural habitat—just remember to keep a respectful distance, as they are a protected species under both state and federal law.
If you’re lucky, you might also witness a pod of spinner dolphins passing through the deeper waters just beyond the main snorkeling zone. These playful mammals sometimes leap from the water or spin mid-air, creating a thrilling surprise for snorkelers and swimmers alike. While dolphin sightings are not guaranteed, they’re a special bonus for those who spend extended time in the water or visit during early morning hours.
With so much marine life so close to shore, Two Step feels like an open-air aquarium, offering an unforgettable glimpse into the underwater world of Hawaii without ever needing to board a boat.
When to Visit
The best time to snorkel at Two Step is in the morning, ideally before 10:00 AM. During these early hours, the ocean is typically at its calmest, with minimal wind and surface disturbance, providing the clearest underwater visibility. Early mornings also mean fewer crowds, allowing you to enjoy the reef and sea turtles in a more peaceful setting. The light angle at this time also enhances visibility, illuminating the reef’s colors and making marine life easier to spot.
By midday and into the afternoon, winds along the Kona coast often pick up, creating choppier water and reducing visibility. These conditions can make snorkeling more difficult and less enjoyable, especially for beginners or those prone to seasickness.
It’s also important to pay close attention to weather and surf forecasts. Avoid visiting during high surf advisories, storms, or heavy swells, as the lava rock shoreline becomes extremely slippery and dangerous under such conditions. Even light rainfall inland can sometimes cause runoff that affects water clarity, so a dry, sunny day is always your best bet.
For the best experience, check the conditions before you go using local snorkel reports or surf forecast apps. And aim to arrive early, not just for safety and water quality, but also for securing a parking spot in this popular location.
Tips for Visiting Two Step
To make the most of your snorkeling adventure at Two Step, a little preparation goes a long way. Here are some essential tips to ensure a safe, respectful, and enjoyable visit:
1. Arrive early
Parking at Two Step is limited and fills up quickly, especially on weekends and during holidays. Aim to arrive before 9:00 AM to secure a spot close to the shoreline. Otherwise, you may need to park farther away along the road or in the paid lot at Puʻuhonua o Hōnaunau National Historical Park nearby.
2. Use reef-safe sunscreen
Hawai‘i has banned sunscreens containing harmful chemicals like oxybenzone and octinoxate, which damage coral reefs. Choose a reef-safe sunscreen made with mineral-based ingredients like zinc oxide or titanium dioxide, and apply it at least 15 minutes before entering the water. Better yet, wear a rash guard or UV-protective swim shirt to reduce your need for sunscreen altogether.
3. Wear water shoes or grippy sandals
The shoreline is made of hardened lava rock, which can be uneven, sharp, and slippery, especially when wet. Protect your feet and avoid slipping by wearing sturdy water shoes or sandals with good tread. Avoid going barefoot, even for a short distance.
4. Give turtles space
Hawaiian green sea turtles are a protected species under state and federal law. It is illegal to touch, feed, or harass them in any way. Always maintain a minimum distance of 10 feet (3 meters), whether you’re in the water or observing from shore. If a turtle approaches you, gently back away to avoid disturbing it.
5. Respect the coral reef
Coral reefs are fragile, living ecosystems that take decades to grow. Even a single kick from a fin can cause damage. Practice good snorkeling etiquette by floating horizontally, staying relaxed, and avoiding standing on or touching any coral. Keep your fins up and kick gently to reduce sediment and avoid unintentional contact.
6. Bring your own gear
There are no rental shops at the bay itself, so it’s best to bring your own snorkel, mask, and fins. If you don’t own any, you can rent gear from dive shops in nearby towns like Captain Cook or Kailua-Kona.
7. Leave no trace
There are no trash cans at Two Step, so please pack out everything you bring in. Respect the area by leaving it better than you found it, and avoid playing music or making loud noise so others can enjoy the natural sounds of the ocean.
By following these tips, you’ll not only protect the marine environment but also help preserve this incredible spot for future generations to enjoy.
Facilities
There are no restrooms, changing areas, or showers at Two Step itself. However, basic facilities are available at the national park next door.
