#1. Kaneohe Sandbar

Kaneohe Bay sandbar, also known as Ahu O Laka, is the world’s largest naturally formed saltwater sandbar. It is surrounded and protected by the coral reef, which makes it a perfect area to snorkel.
This secluded area is only reached by boat. A boat sails to Oahu’s hidden spots with the scenic background of the Ko’olau Mountains, Gilligan’s Island and Chinamans Hat (Mokoli’i). Here, you will see Hawaii’s diverse marine lives surrounding gigantic coral reefs.

Peel your eyes open. Do you see a turtle?
You must hire a private boat or sign up for a tour to get there. On the bright side, this also means that you will have a semi-private snorkeling experience with a limited number of people.
Plus, an organized tour usually provides all necessary snorkeling gear, including snorkel, mask, fins and life jackets. Besides the epic snorkeling experience, sandbar activities include volleyball, barbecue lunch on the boat and turtle watching.
Hours: 10:30 am – 2:30 pm (no tours on Sundays & public holidays)

#2. Waimea Bay Beach

Waimea Bay Beach is one of the most beautiful beaches on the North Shore. And it is my second favorite snorkeling spot in Oahu.
During summer, the water is calm enough for swimming and snorkeling. The gorgeous sandy beach features crystal-clear blue water. In the center, I had high visibility in super clear water; seeing the ripples on the sandy bottom was unique. I recommend snorkeling both sides of the bay around the rocks to observe more aquatic life.

You can dive off the rock, too! Watching people jump is also fun.
Be aware that the water gets deep pretty quickly from the shore. Also, winter is not the time for snorkeling here; the waves can be as high as 30 feet, making this an excellent destination for experienced surfers.

#3. Hanauma Bay

Hanauma Bay is the most popular snorkeling beach in Hawaii and the most beautiful beach near Diamond Head. The bay boasts stunning scenery with a white sandy beach, palm trees, and turquoise water.
The Nature Preserve is famous for being the habitat for the most diverse fish on Oahu. And the calm shallow water makes it accessible to children and beginners to safely snorkel here.
The underwater visibility could be better, but it gets better further out. While you can spot some fish near the shore, you have to swim out to the reef anyways.
Reservation is required here. This popular spot is open to 3,000 visitors per day. Also, the bay is closed each Monday and Tuesday to preserve the environment.
Insider’s Tip
- The reservation opens at 7 am HST two days in advance. Each 10-minute window has 30-35 tickets only. It is highly competitive, so open the browser with your credit card in hand and refresh at 7 am sharp to secure the spot. All spots get filled up within the first 15-20 minutes. Note that all sales are final, with no exchange or refund.
- Give yourself plenty of time to park and line up before admission. Parking is also super challenging. And no late entries are allowed. For an 8:15 am slot, I showed up at 7:30 am. But about 30 cars lined up from the highway to the parking lot. I barely made it. Once you get in, take trams down to the beach.
Admission: $7.50 per person over 12 years old (2.35% service fee for credit card payments)
Parking: $3 for non-residents. Cash only. Limited, first-come first-serve basis.
Hours: Wed-Sun 6:45 am – 4 pm daily (last entry at 1:30 pm), closed Monday – Tuesday for fish feeding.

#4. Shark’s Cove

Shark’s Cove on the North Shore is a local’s favorite snorkeling and diving spot. The stunning coral beach with dramatic cliff views is ranked the Top Twelve Shore Dives in the World by Scuba Diving Magazine.
Don’t let the name scare you away. The name comes from the shape of the reef. You probably will not see any sharks there. Instead, be ready to capture sea turtles and fish on your Go Pro.
Generally, Shark’s Cove is recommended for intermediate snorkelers as they can go beyond the rock wall to enjoy more aquatic life. Enjoy tamed waves in summer. But stay away from the North Shore’s infamous big waves during the surf season (October through April).
There are only a handful of parking spaces. It is best to go early, like before 9 am. By 9:30 am, the highway around the area gets seriously jampacked!
