This spot is located in a more quiet residential area that is not as focused on dealing with tourist as busier areas, so make sure to drive and act respectfully and peacefully when visiting.

To enter, you will be required to watch a 9-minute instructional safety video as well as pay an entry fee of $7.50.

Snorkeling At Shark’s Cove

This is a naturally protected area that is perfect for swimming and is a great place to see plenty of variety in fish and coral as well as some stunning rock formations.

Do not worry about its namesake, as this cove is not overrun by sharks, but instead this name is because the shape of the rock formation occasionally looks like a shark if you look at it from a particular angle. 

Luckily, this is one of the three areas in O’ahu that is in a Marine Life Conservation District, with the other two being Hanauma Bay and part of Waikīkī beach.

This is great for sea activities as this means there is a guarantee for variety in aquatic lifeforms as well as the life that is there is less likely to fear humans.

The main downside to this spot is that it is only really viable during summer, with the conditions getting significantly rougher in the winter months. Another issue is that nearby parking can be quite busy, so try to go at quieter times, like early morning or mid-afternoon.

If you are an experienced snorkeler, you can go past the rock walls of the cove and potentially see even larger fish.

Snorkeling At Kuilima Cove

This is one of the north shore snorkeling locations on O’ahu and is popular all year round because of its rock walls blocking the disruption of any waves.

However, there can still be varying conditions, so if you are not sure about the safety, check with a lifeguard to get the confirmation you need.

If you want to see turtles, true to its name, this is one of the best snorkeling spots to make sure you have the best chance of seeing them.

If you love coral, this spot also has dense beautiful coral formations that work to be a cleaning station for nearby turtles, which is why it is so likely to see turtles here. The turtles get their shells cleaned by smaller fish that reside near the coral.

This snorkeling location is offshore from Waikīkī but is easy to get to via catamaran, but you can also reach it on a sailing tour or even by kayak if you are confident enough.

Snorkeling At Ko Olina Lagoons

This is one of the best snorkeling locations if you are on the western section of O’ahu.

This location is composed of 4 separate man-made lagoons and while they are small and slightly limited in scope, they are a great choice for beginners to see beautiful tropical fish in safer conditions than a lot of the other choices.

These lagoons are known to be calm, so if you are very interested in tropical fish, this is a great location to practice identifying various types of fish!

While Lanikai is not seen primarily as a snorkeling location, it is a great location to do so. There are some rocks and coral not far offshore and the water in this location tends to be calm and clear, the perfect conditions for snorkeling.

The best location to snorkel on Lanikai beach is the public beach accesses located on Mokulua Drive that is between the intersections at Mokumanu Drive with Kaiolena Drive. 

Due to how calm and relaxed the waters are here, this is a great spot for beginners and kids to go snorkeling for the first time. However, if you are a more advanced snorkeler looking for something more intense, this is not the location to go to.

Also, visibility in this water can vary due to the fine white sand that makes up the beach.

Snorkeling At Waimea Bay

Waimea bay is infamous for its popularity with surfers, but on calm summer days the water can be incredibly calm and clear, with clarity rivaling a swimming pool.

These are the perfect conditions for snorkeling, so if you find yourself near this beach on a calm day, this is a great opportunity to explore the rock formations on this bay. 

This bay is also included in the Pūpūkea Marine Life Conservation District, making it so the amount of fishing that can be done here is limited, meaning this bay has a varied group of aquatic life perfect for snorkeling.

If you are lucky, you might even be able to seen dolphins near the bay.

However, similarly to Shark’s Cove, this area is only suitable for snorkeling during summer, this is because of the high surf present in the winter season.

Snorkeling At Sans Souci Beach

This is one of the best snorkeling spots in Waikīkī and is included in the Sans Souci Recreational Park, which also holds the Waikīkī Marine Life Conservation District.

Similarly to other protected zones, the amount of fishing here is limited to make sure the aquatic biodiversity remains natural and also makes it so snorkelers have plenty to admire.

This also makes it so the fishes present are not as scared of humans, making it easier to get a look at them up close.

This is a perfect choice if you are staying in or close to Waikīkī and even if you do not want to snorkel here, this is a great location to spot turtles and a wide variety of tropical fish.

Snorkeling At Electric Beach

Electric Beach (also known as Kahe Point) is a great snorkeling spot that is on the west side of O’ahu’s power plant. Because of this, there is an underwater pipe that provides warmer water into this section of the ocean, which is a couple of hundred yards off the shore.

Because of this unique temperature, there is a massive variety of wildlife that includes turtles and a massive variety of tropical fish, sometimes even sharks.

However, this is only an appropriate place to snorkel for those who are advanced and experienced. This is because reaching this spot takes a long swim offshore and there can be strong currents.

Snorkeling At Ka’ena Point

This snorkeling location is defined by its extensive rocky coastline, which makes exploring with snorkeling a great idea.

However, this spot does not have as much biodiversity as somewhere with conditions like Electric Beach, it does have plenty of crabs and crustaceans that are hidden between the rocks, which makes exploring the details rewarding.

The best way to get to Ka’ena Point is off the end of Farrington Highways on the western side of O’ahu. After this, just go to Yokohama Beach.

Make sure before choosing to snorkel here to pay attention to the surf, as currents and swell are likely to converge on the west and northern parts of the island.
