7 Important Tips for Snorkeling the Big Island

Before we get into the best places for snorkeling on the Big Island, we first recommend you read the following snorkeling tips to ensure the best possible experience.

In addition, these tips will help to keep you and the environment safe, as well as saving you a few bucks!


1. Bring Your Own Snorkel Gear

Save time and money by bringing your own snorkel gear to the Big Island.

Unless you plan on only doing snorkel tours on the Big Island, we highly recommend bringing your own snorkel gear.

The cost of renting snorkel gear on the Big Island is less than on some other islands at around $10-15 per day. However, it is still typically cheaper to buy your own gear!

Additionally, having your own snorkel gear provides flexibility and the convenience of being able to snorkel whenever you want without having to worry about picking up or dropping off rentals.


2. Only Use Reef-Safe Sunscreen

Make sure you use reef-safe sunscreen.

Did you know that traditional sunscreens are toxic to coral reefs? The NPS estimates that 4,000-6,000 tons of sunscreen pollute our reefs each each year, with the most popular spots seeing the most damage.

Hawaii is the first state to mandate the sale of reef-safe sunscreen. However, many “reef-safe” sunscreens still use harmful chemicals. Always check the ingredients prior to purchasing, and look for mineral sunscreens such as this one by Stream2Sea.

You can also reduce the amount of sunscreen you use by wearing a long-sleeve rashguard to protect you.


3. Protect the Reef

In addition to providing a home to millions of different species, coral reefs also play an important role in protecting the coastlines from storms and erosion.

While corals can look like rocks, they are in fact a living animal and are very fragile.

To ensure the protection of the reef, always be careful when snorkeling to avoid touching or stepping on coral. Not only can it be broken easily, but touching it damages its protective layer and exposes the coral to pathogens.


4. Follow Leave No Trace Principles

The underwater ecosystems you’ll encounter while snorkeling on the Big Island are very delicate.

By following leave no trace principles and being respectful of the environment, we can help keep the beauty of the oceans intact for generations to come.

Be respectful to wildlife and do not touch any animals. Marine life is particularly susceptible to the germs we carry and even a gentle touch can do a lot of damage.


5. Stay Safe with the Buddy System

You never know when you may run into trouble and sudden “shallow water blackouts” can occur. Having a buddy with you ensures you have someone to help out if you ever need it.

Better still, you have someone to enjoy the fun with!


6. Choose the Right Time of Day

While it is possible to snorkel on Big Island throughout the day, choosing the best time can tremendously help your experience.

The best time of day to snorkel on the Big Island is in the morning, about 1-2 hours after sunrise.

Head to the beach early for the best chance of calm water and good visibility. During the morning hours, there is typically less wind and waves, and therefore better ocean conditions for snorkeling.

However, if you arrive too early, the sun will not yet be overhead enough to provide valuable light. This is why it is best to wait a couple of hours after sunrise.

Additionally, avoid snorkeling after heavy rain or during high winds. During these times, visibility is reduced and water conditions can be less ideal.


7. Bring an underwater camera

Pack an underwater camera to ensure you can capture the incredible, vibrant aquatic world that awaits you on the Big Island.

Few vacation memories compare to coming face-to-face with a turtle for the first time or being surrounded by a kaleidoscope of fish; make sure you can capture these moments to treasure forever.

There are many different underwater cameras you can get depending on your skill level and interest in photography. However, the GoPro, or similar adventure cameras, are the smallest, toughest and easiest to use while also being reasonably priced.

More Snorkeling Safety Tips

While snorkeling on the Big Island is relatively safe, there are always risks when swimming in the ocean. You can minimize these risks with the following steps:

  • Always check current conditions, including weather, warning flags, and currents.
  • Know your own limits.
  • Only snorkel with a buddy (or consider booking a tour).
  • Use a life vest if you’re not a confident swimmer.
  • Stay close to shore.
  • Always be aware of your surroundings.
  • Do not use full-face masks (these create a CO2 buildup which can cause you to become disoriented, or, even lose consciousness).
  • Only snorkel during daylight hours.

Top 20 Best Snorkeling Spots on the Big Island

1. Manta Ray Village Night Snorkel

Few experiences compare to floating in the ocean under the stars as a gentle giant appears, majestically swooping just below you. It is truly magical to watch the manta rays come belly-to-belly with you for a mouthful of dinner.

Not only is it the best snorkeling on the Big Island, it is also the one “must-do” on your Big Island bucket list. Having personally done this tour five times (yep we love it that much) we cannot recommend it highly enough; if you only book one tour on the Big Island, make it this one!

No snorkeling experience is required, you’ll just float with your feet on a noodle!

🐠 Snorkel Tip: If possible, book the earlier tour to allow you to watch the sunset from the boat on your way to Manta Village.


2. Captain Cook Monument

With warm, calm, and clear waters, Captain James Cook Monument is a world-renowned snorkeling destination and is considered the best snorkeling spot in all of Hawaii.

Located within Kealakekua Bay marine sanctuary, the pristine waters offer a spectacular diversity of marine life. In addition to schools of brightly colored fish, you can also expect to see the occasional sea turtles and will almost always see pods of spinner dolphins from the boat.

While it is technically possible to get to this snorkel spot without a tour, it requires a very long drive and a challenging hike or kayak. The boat tours are affordable and provide a much more pleasant experience, and save a lot of time as well.

During the winter months, you will also likely spot a few migrating whales if you do a boat tour!

🐠 Snorkel Tip: Choose a morning tour for the best chance of good weather and ocean conditions.


3. Two Step (Hōnaunau Bay)

Most agree that Captain James Cook Monument is the best place to snorkel on the Big Island, but Two Step comes in a close second and does not require a tour or long hike.

The coral garden at Two Step is rich and teeming with aquatic life, making it easy to check many species off your Hawaii reef fish guide! The deeper waters in the center of the bay are regularly visited of spinner dolphins and Hawaiian monk seals.

Services are limited here so plan accordingly. Also, it is so-named because it requires two slippery steps to get into and out of the water. People with mobility issues may struggle at this location and should instead consider Kahalu’u Beach Park.

🐠 Snorkel Tip: From the entry steps, head out at a 45-degree angle to the right, you will come to a sand patch at about 30-40ft with “Aloha” written out in cinder blocks on the bottom.


4. Kahalu’u Beach Park

Kahalu’u Beach Park offers a wide protected bay on the Kona coast with some of the most easily accessible and best snorkeling on the Big Island.

The fringing reef helps to protect the bay and typically keeps it free from currents. Additionally, its easy shore access and shallow depth make it a good place for kids and beginner snorkelers.

For those that are more experienced, head to the center of the bay where you can find larger coral heads.

The entrance for snorkeling is at the southern end of the bay and involves walking over some rocks which can be slippery and uncomfortable. If you chose to wear water shoes, be sure that you only stand on sand once in the water.

There is a convenient patch of sand after entry where you can stand and put on your snorkel gear.

🐠 Snorkel Tip: Be sure to chat with the volunteers at the Kahalu’u Bay Education Center in the park. They provide a wealth of knowledge about the underwater world here.


5. Kamakahonu Beach (King Kam Beach)

Kamakahonu Beach, also known as King Kam Beach, is located right in the heart of Kona Town.

The small, sheltered beach provides shallow and usually gentle waters, making it ideal for beginner snorkelers just learning.

As well as being a popular snorkel spot on the Big Island, it is also a site of cultural importance. It was the final home of King Kamehameha from 1812 until his death in 1819, and a reconstruction of his personal temple can be seen just offshore.

🐠 Snorkel Tip: Head to the right (north) out of the bay for the best snorkeling. However, once out of the bay be aware of boat traffic. Do not turn left as this area is busy with boats coming in to and out of Kailua Pier.

6. Kaiakeakua beach

Just 30ft south of King Kam Beach on the other side of Kailua Pier is Kaiakeakua Beach. While the beach is more just a small patch of sand than a true beach, it serves as an entry point for snorkeling Kailua Bay.

The water here typically has excellent visibility and it’s a common place to spot local honu (sea turtles in Hawaiian).

🐠 Snorkel Tip: Snorkeling is only permitted within the buoys as the pier is used for large boats.


7. Makaiwa Bay (Mauna Lani Resort)

Soft white sand and crystal clear waters await you at Makaiwa Bay within Mauna Lani Resort. The small beach provides easy entry for snorkeling the shallow reef here.

Just 20 yards from the shore you will discover the coral reef and the many creatures that call it home, including reef fish, octopus, and eels.

More advanced snorkelers can venture further out where the water clarity becomes even better and large schools of fish can be found.

🐠 Snorkel Tip: This is a great Big Island snorkel spot for beginners or snorkeling with kids as the bay is sheltered and usually has calm water.


8. Mauna Kea Beach (Kaunaʻoa Beach)

Along the Kohala Coast north of Kona and Waikoloa, Mauna Kea Beach provides excellent snorkeling in the summer when the water is typically calmer.

Considered one of the best beaches on the Big Island, the picturesque white sand beach provides easy entry to the water.

Public parking is available but is limited so arrive early to ensure a spot. Visibility is also better in the morning so it’s a win-win!

🐠 Snorkel Tip: For the best snorkeling, head to the rocky outcrop at the south end of the beach.


9. Hapuna Beach

When the water is calm, Hapuna Beach provides some of the best snorkeling on the Big Island. However, the visibility is typically not so good due to mixed-in sand and a freshwater layer that sits on the surface.

The water around the rocky points to the north and south of the beach provides the most interesting areas for snorkeling.

Turtles are more frequently seen at the northern end of the beach.

Reaching these spots requires a bit of a swim and takes you out of the line of sight of the lifeguards here. Therefore, we only recommend this only for advanced snorkelers with a buddy.

🐠 Snorkel Tip: Do not snorkel here if the surf is up as the waves can get big making snorkeling dangerous.


10. Richardson Ocean Park (Richardsons Beach Park)

While the Kona and Kohala coasts on the west of the island are most famed for their impressive snorkel destinations, Richardson Ocean Park should not be overlooked.

Located on the east coast of the Big Island, Richardsons Beach Park offers the best snorkeling on the east side of the Big Island. There are several factors that lend to this beach being such a choice spot for snorkeling.

Its waters are fairly shallow and almost entirely current free making swimming here easy. On top of this, part of the beach is a protected marine conservation area. Finally, fresh water feeds into the ocean from nearby springs creating an ideal environment for marine life to thrive.

🐠 Snorkel Tip: This is a popular spot for local families at the weekends so try to visit during the week to avoid the crowds.

Best Big Island Snorkeling Tours

While there are some great snorkeling beaches on the Big Island, some of the best places for snorkeling can only be reached by boat.

There are also some other benefits that come with booking a snorkel tour rather than doing it yourself.

By booking a tour, you will have expert guidance from a local who knows the reefs better than anyone. This means that you’ll get to the best places based on the current conditions and have someone to direct you to the most beautiful areas.

Boat tours also give you a unique perspective of the island, as well as provide the opportunity to spot other wildlife such as dolphins and whales.

Most tours will also include some refreshments, snorkel equipment, and interesting information on the area. However, check individual tours for specific inclusions.

The most popular places for Big Island snorkel tours include Manta Village Night Snorkel and Captain Cook Monument, both of which we have done repeatedly and highly recommend.
