Just the right size!
Great people. Small but not too small boat. There were 9 guests. We really liked Seth and Addy as our captain and crew. They were very welcoming!

You NEED to do this trip.
I was thoroughly impressed with Captain Dennis and Rey Rey(not sure on the spelling. Captain Dennis was fun, informative, safe, and very personable. He took time to explain answers to our questions and was very patient with us when we asked about boundaries. Rey Rey was so helpful and kind. She handled other guests with grace and kindness when they needed extra help getting into and off of the boat. I would HIGHLY recommend this crew to anyone. My brother and I are already planning another trip for this excursion alone. So good.

Best snorkel Experience
I have been snorkeling on many of the Hawaiian island's and this one was a favorite! The first location is very hard to get to by foot as there is a long hike so that was neat. The second location is more easily accessible so we did go back the next day because it was my favorite! I saw so many different colored fish, variety of sea urchins and vibrant colored coral reef. The staff we had were very friendly and ensured we had a safe/fun trip! Highly recommend
Response from the operator: Mahalo! A favorite among all the Hawaiian islands -- that truly means a lot! We are so glad both spots delivered such stunning marine life and that you even came back the next day for more. We appreciate you choosing us and hope to welcome you back on the water again someday!

Bad Customer Service
The crew’s attitude was extremely disappointing. It was honestly the worst customer service I have ever experienced. On the way to the tour, I even transferred an extra $25 to our Uber driver just so I could get $20 in cash to tip the crew afterward. By the end of the trip, however, I decided not to leave a single dollar because I genuinely didn’t feel they had earned it. Perhaps my expectations were higher because I had such an outstanding snorkeling experience in Honolulu. That’s on me—I probably shouldn’t have expected the same level of service everywhere. Even so, in over a decade of traveling, I have never encountered a crew that felt so unprofessional in terms of customer service. They came across as people who were simply tired of their jobs and eager for the day to end, rather than people who enjoyed taking care of their guests.
Response from the operator: Aloha Hongbo, We are sorry to hear that you were disappointed with your experience. I reached out to twice for more information; however, it sounds like you are mostly disappointed that you didn’t know how to swim and our staff wouldn’t do the swimming for you. We must be very clear that swimming ability is a required safety prerequisite for this snorkeling tour. This requirement is stated in our listing, reviewed during check-in, and confirmed again by the captain once guests are aboard. Despite being asked several times, you did not disclose that you were unable to swim until it was time to enter the water. For safety reasons, our captain and crew cannot leave the vessel to personally swim guests around the bay. While every tour company and snorkel location may operate differently, guests are responsible for reviewing and meeting the stated requirements before booking. We always want our guests to have a safe and enjoyable experience, but we cannot compromise safety standards to accommodate guests who don’t meet the minimum requirements for the tour.

See lots of wildlife with a knowledgeable crew
Colby and Seth were great. Kept everyone’s safety in the forefront and led a great snorkeling adventure. Their knowledge about the sea was apparent when we saw two bottlenose dolphins. What a great family friendly excursion.
Response from the operator: Mahalo! Bottlenose dolphins on a snorkel adventure -- what a bonus! We are so glad our crew's knowledge and safety focus made it such a wonderful family excursion. We appreciate you choosing us and hope to welcome you back on the water again someday!

Why this scores 82
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Two Reef Snorkel Trip-See Captain Cook Monument & Sea Caves: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Big Island of Hawaii.
How much does Two Reef Snorkel Trip-See Captain Cook Monument & Sea Caves cost?
+
Prices start at $119 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Big Island of Hawaii usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Two Reef Snorkel Trip-See Captain Cook Monument & Sea Caves take?
+
Plan for about 4 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Big Island of Hawaii is not rushed.
Is Two Reef Snorkel Trip-See Captain Cook Monument & Sea Caves worth it?
+
It holds an Outty Ranking of 82 out of 100, which we label "Exceptional". That score blends traveler sentiment (4.8/5 across 374 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Big Island of Hawaii, and how flexible the cancellation terms are.
Can I cancel or reschedule Two Reef Snorkel Trip-See Captain Cook Monument & Sea Caves?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Two Reef Snorkel Trip-See Captain Cook Monument & Sea Caves suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 4-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Two Reef Snorkel Trip-See Captain Cook Monument & Sea Caves?
+
Around 131 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Big Island of Hawaii can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Big Island of Hawaii and add a light layer if any part of the 4-hour experience runs outdoors or after sunset.
Where does Two Reef Snorkel Trip-See Captain Cook Monument & Sea Caves start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Big Island of Hawaii within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Big Island of Hawaii?
+
The Big Island is volcano country: Hawaii Volcanoes National Park tours, Mauna Kea summit stargazing, night manta ray snorkels off Kona, Waipio Valley lookouts and coffee farm visits. Summit tours have real altitude rules, so we weight safety detail. On Outty we rank every Big Island of Hawaii experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include KONA Manta Ray Night Snorkel - FREE re-ride if no Sightings, Big Island: Captain Cook Snorkel On A Power Catamaran With Lunch, Big Island in a Day: Volcanoes Waterfalls Sightseeing and History. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Big Island of Hawaii?
+
April to October, though the island runs year round. Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Big Island of Hawaii?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
