Check Out the Best Snorkeling Spots in O’ahu
1. Kuilima Cove
One of the most serene snorkeling spots on O’ahu, Kuilima Cove is protected from the waves by a natural rock barrier. This small bay is located on the North Shore of the island. It’s an excellent kid-friendly option because of the calm waters and unobstructed views. You’ll encounter a variety of underwater fish, including butterfly fish, parrot fish, damselfish, perch, triggerfish, and more! Relax on the beautiful white sandy beach after you’ve had your fill of excitement for the day.
2. Kahe Point
The waters at Kahe Point Beach Park are exceptionally clear. This favorite snorkeling destination is located on the west side of O’ahu. Also known as “Electric Beach” because of the nearby electric power plant, the water here is several degrees warmer than the surrounding ocean. This warm water creates an attractive habitat for a wide variety of aquatic life, making it ideal for snorkeling.
This O’ahu snorkeling spot is best for the intermediate to advanced level snorkeler. There is a moderate distance to swim, and no lifeguards are present.
It is fairly common for snorkelers to encounter green sea turtles at this location. It’s important to remember that you should only look. Do not touch! Sea turtles are endangered, and it is illegal to get too close to them. In addition to the turtles, you might see snapper, hawkfish, surgeonfish, various crustaceans, and invertebrates!
3. Hanauma Bay
Hanauma Bay is the most famous snorkeling spot in Hawaii because of the high fish population and calm, protected waters. Located on the southeastern side of the island, this high-traffic attraction is minutes from Honolulu. It has been recognized as a protected marine life conservation area and underwater park since 1967. You do have to pay an entrance fee of $25 per person (13+). Active-duty military, local residents with a state ID, and children 12 and under are free.
There is a mandatory 9-minute safety video to watch before walking down the hill to the lower level, where you can start snorkeling. If you need assistance getting to the beach, a tram service is included with the entry fee.
You won’t regret adding a visit to this location on your 5-day Oahu itinerary!
4. Kaena
While Hanauma Bay is beautiful, it is not free from crowds. Kaena, on the other hand, is a mile-long stretch of beach that offers some of the most beautiful underwater views imaginable. Here, you’ll avoid the crowds and still see marvelous marine life below the surface of the water. You can expect to see squirrel fish, needlefish, turtles, and more! You’ll remember this Oahu excursion for the rest of your life!
5. Sharks Cove
Divers and snorkelers alike venture to O’ahu’s North Shore to admire the bustling wildlife that thrives at Sharks Cove. This is a top snorkeling destination located within the Pupukea Marine Life Conservation District and is free. You will find rocky tide pools, caves, and abundant marine life. Summer is one of the best seasons to visit. It features 8–15 feet of deep, clear, beautiful water. Water shoes are necessary due to the presence of sharp rocks.
This is an advanced beginner to advanced snorkeling experience.
If you’re feeling extra adventurous, consider booking a shark diving tour with Hawaii Shark Encounters! There’s nothing more thrilling than seeing sharks, even from the safety of a professional-grade shark-diving cage!
6. Mermaid Caves
O’ahu’s Mermaid Caves, located on the western shore, feature a series of sea caves and lava tubes carved into the rugged coastline. Sunlight pours in from different angles, creating an enchanting setting—just like a scene from “The Little Mermaid”.
Park near Nānākuli Beach and walk along the rocky coastline from the south end. You will not find any signs, so keep an eye out for a large hole in the rocks. While many will explore the rock and even jump in, snorkeling is for experienced or advanced snorkelers. Low tide offers the best opportunity to enjoy the captivating blue waters of the Mermaid Caves.
This is not only one of the best snorkeling spots on O’ahu—it is also a hidden gem!
