Snorkeling Molokini: 10 Things Every Visitor Should Know

Snorkeling Molokini – 10 Things Every Visitor Should Know

A snorkel tour to Molokini Crater is one of the most popular and unique experiences for visitors to Maui. The crater, a crescent-shaped islet located about three miles off Maui’s southwest coast, is a partially submerged volcanic caldera and a Marine Life Conservation District, known for its crystal-clear waters and vibrant marine life. Here’s everything you need to know before heading out on a Molokini snorkel tour.

1. Molokini Is A Unique Marine Environment

Molokini Crater, formed over 230,000 years ago, is a partially submerged volcanic caldera off Maui’s coast. Its crescent shape helps shield snorkelers from waves and creates a calm underwater environment perfect for spotting coral, tropical fish, and very occasionally, larger marine life like reef monk seals, reef sharks, and rays. This protected area is a Marine Life Conservation District, which maintains its status as one of the most pristine reef ecosystems in Hawaii.

Visibility at Molokini can reach up to 150 feet on clear days, making it ideal for snorkelers eager to explore the intricate coral formations and observe marine life up close. The abundance of fish species and the vibrant coral make it a top destination for snorkelers and divers alike. Learn more about wildlife at Molokini here.

2. Weather and Ocean Conditions Matter

Weather and ocean conditions significantly affect the quality of a Molokini snorkel tour. Morning tours are typically recommended, as the trade winds tend to pick up in the afternoon, causing choppier seas that can affect snorkeling visibility and comfort. For optimal conditions, look for a morning departure, especially if you’re prone to seasickness or simply want the calmest waters. You can always check the forecasts and even current conditions at Molokini on our Molokini Weather & Waves page!

Additionally, while Molokini itself is sheltered, the open channel can be a bit rough depending on the time of year. If you’re concerned about sea conditions, check with your tour company ahead of time, and consider taking precautions against seasickness if you’re sensitive to ocean swells.

3. Select Your Best Tour Operator

Molokini snorkel tours vary widely in offerings and vessel types. Larger catamarans, like the Calypso, provide a stable and comfortable ride with more space for amenities, making them great for families or those looking to relax. Smaller vessels, like the Blue Water Rafting inflatable rafts, offer a more adventurous experience with fewer people on board, often allowing for quicker transit to Molokini and a more intimate tour atmosphere.

Some tours are exclusively Molokini-focused, like the Blue Water Rafting Molokini Express, while others may combine snorkeling with whale watching (seasonal), like Pacific Whale Foundation, or additional stops at other snorkeling spots like Turtle Town on the Calypso. Additionally, some boats still offer SNUBA as an upgrade experience, like aboard the Four Winds. Look for a tour that aligns with your preferred experience level and includes any extras you want, such as meals, beverages, or on-board naturalists for marine education.

4. Snorkeling Equipment and Preparation Are Key

Most tours provide snorkeling gear, including masks, fins, and snorkels. You are also welcome to bring your own gear if you prefer. However, be aware that most boats do not allow full face snorkel masks.

If you’re looking for extras like prescription masks, or just want to know you have excellent gear for the trip before you go, get your gear at Auntie Snorkel and bring it with you! Our premium snorkel set rentals include top quality clear silicone mask, dry snorkel, soft rubber fins, defog solution, a fish ID card, and a bag to carry it all. We like our own equipment so much, we usually choose to bring it along with us on boat excursions!

Importantly, most boats provide plenty of floatation options, like jackets, belts, and boogie boards, to help keep you safe, and make your snorkel experience more relaxing. 

5. Be in the Know About Safety & Environmental Protection

Safety is paramount, and most tour companies include a safety briefing before entering the water. Lifeguards and guides are typically on hand to assist with equipment or provide snorkeling tips. It’s important to follow the guides’ instructions closely to avoid putting yourself in danger or damaging the fragile coral and marine ecosystem.

Your guides will tell you what areas are safe to explore, and where you shouldn’t go (like outside the crater or onto the shoreline of Molokini itself). And remember, Molokini is a protected area, so touching coral, fish, or any other wildlife is strictly prohibited. Following these guidelines not only protects the environment but enhances your overall experience by keeping the waters clear and the marine life thriving.

6. Look Out for Seasonal Wildlife Viewing Opportunities

While snorkeling at Molokini is a fantastic experience year-round, the winter months bring an extra layer of excitement: whale watching season! From December to April, the warm Hawaiian waters become a migration hub for humpback whales, who journey here each year to breed, give birth, and nurse their young. Many Molokini snorkel tours offer special combined trips during this period, where visitors have the chance to witness these magnificent creatures en route to or from the crater.

Guides on these combined tours are often knowledgeable about whale behavior and can share fascinating insights about their migration patterns, social structure, and unique vocalizations. As you travel toward Molokini, you might be lucky enough to see mother whales with their calves or even groups of males competing for attention—a rare and awe-inspiring sight. Some boats are equipped with hydrophones, which allow passengers to listen to the haunting, melodic songs of the humpbacks, making the experience even more immersive.

The chance to snorkel with tropical fish and colorful coral reefs, followed by an encounter with these gentle giants, is a memorable and unique aspect of visiting Molokini in the winter. Just remember to bring a camera, as you’ll want to capture the awe of these incredible encounters both below and above the surface!

7. Bring Along the Essentials

Most snorkel tours recommend bringing only essentials:

• Bring a light jacket for wind protection,
• bring your swimsuit,
• bring a towel, and
• pack any extra sun protection, such as reef-safe sun block, hats, rash guards, or polarized sunglasses.

Cameras and waterproof cases are popular among snorkelers who want to capture their experience. Many boats will rent underwater cameras to you, but be prepared for the extra charge to be quite high. Fortunately, Auntie Snorkel has the best rates on GoPros for your trip!

Molokini’s water temps can feel a little cooler than just offshore Maui island. Plus, you’ll probably want to be in the water longer than a quick snorkel from shore. So, it can be a good idea to keep yourself warm with a wetsuit top or spring suit! Many boats will have some wetsuits for additional rental fees. However, we suggest renting your wetsuit from Auntie Snorkel to be sure you have the best fit before you go and to be sure you get the best rate.

Finally, most boats also either provide meals or have snacks and refreshments available, but check in advance if you’d like to bring your own or have special dietary needs.

8. Understand the Cost and What’s Included

Molokini snorkel tours vary widely in price, typically ranging from $150 – $260 per person, depending on the vessel, length of the trip, amenities, and group size. Check what’s included in the tour—some include breakfast, lunch, and refreshments, while others may offer add-ons such as SNUBA (a cross between snorkeling and scuba diving) for an additional fee. Considering what’s included can help you select a tour that aligns with both your budget and preferences.

9. First-Time Snorkelers Can Do Molokini, Too

If you’re new to snorkeling, a Molokini tour is a fantastic way to start. The crater’s natural crescent shape creates a sheltered area with calm, clear waters, making it an ideal spot for beginners. Tour guides are skilled at helping first-timers feel comfortable, offering tips on breathing techniques, fin use, and buoyancy control. Many tours provide flotation devices like vests and belts, allowing you to relax and focus on enjoying the underwater scenery without worrying about staying afloat.

Guides often conduct Snorkel 101 briefings, covering everything from mask adjustment to basic safety practices, which is especially helpful for beginners. With their support and encouragement, you’ll quickly build confidence in the water. By the end of the trip, you’ll feel comfortable and ready to explore more of Hawaii’s marine life!

10. Bring Respect for Hawaiian Culture and History

Molokini is more than just a snorkel site; it has historical and cultural significance for the Hawaiian people. There are many different accounts of Molokini in Hawaiian oral legend. Some tell of Molokini as a child of Earth Mother, Papa. Others identify Molokini as the placenta from the birth of the neighbor island of Kaho’olawe.

Another legend that prevails in various forms describes how the fire goddess Pele and a rival of hers (a Mo’o – or gecko) both harbored affection for the same prince. In a fit of jealousy, Pele cut the Mo’o in half and threw her into the ocean. As a result, Molokini Crater emerges from the tail of the Mo’o. The head is Red Hill, the crimson cinder cone known as Pu’u O’lai situated across the channel at Makena Beach. 

Many tour operators share stories like this to enhance your understanding and appreciation of the area. Showing respect for the cultural significance of Molokini by following guidelines and treating the environment gently contributes to the preservation of this beautiful site.
