Review · BLUE CAVE & GROTTO TOURS
Snorkeling in the Blue Cave area【Okinawa Prefecture: Free feeding & photo images!English and Chinese speaking guide available!
Blue water, bright fish, and a very practical price. This two-hour snorkeling trip from Onna-son combines beginner-friendly instruction with a swim toward the famous Blue Cave. I especially like the shallow-water practice before heading out and the fact that underwater photos and videos are included. You also get to feed the fish, which adds a little fun for children and first-time snorkelers.
The main catch is that the Blue Cave is not guaranteed. Wind, waves, and water conditions can send the group to a nearby beach instead. The site can also be crowded, English support may be limited on some departures, and the actual time in the water is usually about 45 minutes to one hour.
Key points to know before booking

- Beginner-friendly instruction: You practice breathing and using the mask and snorkel in shallow water before swimming farther out.
- Blue Cave access depends on the sea: The cave may close because of waves or tide conditions, with a nearby beach used instead.
- Free underwater images: The guide takes photos and videos and transfers the files to your smartphone after the swim.
- Fish feeding is included: You can see tropical fish, starfish, coral, and other sea life at close range.
- Expect a crowded popular site: Cape Maeda and the Blue Cave attract many snorkelers, especially during busy periods.
- The strict age and arrival rules matter: Participants over 59 cannot join, and you must meet at the parking lot 15 minutes early.
What this Okinawa snorkeling trip is really like

This is a straightforward, low-cost introduction to snorkeling around Cape Maeda, one of Okinawa’s best-known water recreation areas. You meet at Island Club, at 615-2 Yamada in Onna-son, complete the registration paperwork, and get ready with the supplied equipment.
The advertised duration is about two hours, but that includes check-in, changing, the safety talk, equipment preparation, showering, and receiving your photos. Plan on roughly 45 minutes to one hour in the water. That is enough time for a pleasant introduction, but it may feel short if you already snorkel well and want a long, unhurried session.
The price is listed at $19.82 per person, which is unusually low for a guided snorkeling trip that includes equipment, insurance, fish feeding, and underwater images. You must also pay a 300-yen facility charge in cash. That fee covers parking, the shower, and hair dryer use.
For a first snorkeling outing, this is good value. You are paying for supervision, equipment, help in the water, and photographs you would otherwise need to take yourself. The value is less clear if you are an experienced swimmer who already owns gear and wants freedom to explore at your own pace.

Meeting at Island Club and getting ready

The meeting point is the Island Club parking area in Onna-son. You need to arrive 15 minutes before the scheduled start. This is not a casual suggestion. If you arrive late, you may be refused entry and charged the full amount.
The strict timing makes sense from the operator’s point of view. The group needs to complete paperwork, fit masks and fins, hear the safety instructions, and leave together. Still, you should build in extra time for traffic and finding the parking area, particularly if you are coming from another part of Okinawa.
The facility charge is paid on site in cash, so keep 300 yen per person ready. After check-in, you receive the necessary gear. Equipment listed for the activity includes a wetsuit, aqua shoes, fins, and a snorkel mask. The included insurance is another useful feature for a supervised water activity.
The group can include as many as 50 people. That is a large maximum, and it helps explain why the experience may feel busy. The guide’s attention is divided among the group, so you should be comfortable following instructions and staying close to the others.
Shallow-water practice for first-time snorkelers
The safety lesson is one of the strongest parts of this experience. The guide explains how to use the snorkel, how to breathe carefully, and how to get comfortable with the equipment. You then practice in shallow water before heading toward the cave.
That short training period matters. Many beginners struggle not with swimming, but with the strange feeling of breathing through a tube while wearing a mask. Practicing first gives you a chance to clear your mask, adjust the mouthpiece, and learn how the fins feel.
The guides generally receive strong praise for being patient and helpful. Katsuya and Aka are two names that received special appreciation, and several families found the guides reassuring with children and nervous swimmers. One guide was described as taking particular care of a 10-year-old participant.
The experience is not perfect for everyone. One complaint described a guide as overly bossy while helping a participant with fins. That may have been a communication problem or a difference in expectations, but it is worth knowing that the teaching style can feel firm. In the water, clear instructions and quick corrections are part of keeping a mixed-skill group safe.
Swimming toward the Blue Cave

The second part of the outing takes you toward the Blue Cave, a roughly 30-meter-long sea cave with an open air space inside. Sunlight enters through the cave opening and reflects off the water, creating the blue glow that gives the cave its name.
The effect can be beautiful, especially when the water is calm and the light is right. Fish gather in the area, and the guides may feed them so you can see them close up. The underwater photos often show the blue water, the fish, and your group better than most casual phone pictures could.
Keep your expectations sensible. You do not spend the whole outing inside the cave. Several people found the cave smaller than expected and said the group entered only the beginning area before moving on. The site is popular, so you may share the water with snorkelers and divers. In busy conditions, you might spend as much effort avoiding fins and other swimmers as watching the fish.
Early morning departures can improve the experience. A 7 a.m. outing was described as quieter, with bright light, comfortable temperatures, and many fish. It cannot guarantee an empty cave, but an early start is a sensible choice if you want less crowding.

The nearby beach option when the cave closes

The Blue Cave is not guaranteed on any date. The operator decides the location according to waves, wind, and the condition of the strait. If swimming inside the cave is prohibited, the group goes to a nearby beach instead.
This is an important point when deciding how to book. You are buying a guided snorkeling experience in the Blue Cave area, not a guaranteed cave entry ticket. Rain alone does not necessarily cancel the activity, but rough water can change the route or stop the tour.
The nearby beach can still be worthwhile. One group that missed the cave because of high tide and weather conditions saw many fish and had a very enjoyable swim. Another group found the alternate location beautiful and felt the underwater life made up for losing the cave.
You should also know that the cancellation terms are strict. If the operator changes the spot but still runs the activity, a cancellation fee may apply. If poor weather causes the entire experience to be canceled, you are offered another date or a full refund. The tour is otherwise non-refundable and cannot be changed for personal reasons.
Tropical fish, feeding, and underwater photographs

Fish feeding is included in the price. It gives beginners something easy to focus on and brings fish close enough for clear photographs. You may see tropical fish, starfish, coral, and other sea life.
The fish are the most reliable attraction here. Even when the cave closes, the snorkeling can still be rewarding because the surrounding water contains plenty to see. Several participants described the water as clear and the number of fish as impressive.
The feeding also raises an environmental concern. One experienced snorkeler objected to the use of fish food and reported seeing guides step on coral. That is a serious criticism. If reef care matters to you, ask the guide how to avoid touching coral and keep your fins away from the bottom. Do not stand on the reef, even if other people do.
The free images are a real benefit. Guides use an underwater camera or GoPro and send the files to your smartphone after the swim. You can concentrate on swimming instead of trying to operate a camera while managing your mask and fins. Image quality will vary with water clarity and the guide’s timing, but several participants felt the photos alone made the low fee worthwhile.
English, Chinese, and communication on the tour

The activity is advertised with English and Chinese-speaking guide support. That is helpful, but you should not assume every departure will have a fluent English guide. Some participants received clear English assistance, while others found that the staff spoke very little English.
The basic process is simple enough to follow through demonstration: breathe through the snorkel, stay near the guide, and follow hand signals. Still, English explanations about fish, coral, or safety may be limited depending on who leads your group.
If you have a medical concern or are unsure about your swimming ability, include it in the booking remarks before you go. The operator says the staff will respond to questions. Do not wait until you are standing on the beach in a wetsuit.
Crowds, life jackets, and the feel of the swim

This is a popular public snorkeling site, not a private reef outing. Conditions can range from pleasantly quiet to very crowded. At busy times, people may bump into one another, and you may need to avoid fins and hands in the water.
Some participants also found that snorkeling with a life vest limited movement. That trade-off is common in beginner group trips. A flotation aid can help a nervous swimmer stay calm, but it can make it harder to turn, kick, or look down comfortably.
The trip suits you best if you want support rather than independence. Families, first-time snorkelers, and people who want photos without paying a separate photographer are the natural audience. Strong swimmers and experienced snorkelers may prefer a smaller group or a rental setup that lets them choose their own route.
The tour has a moderate fitness requirement. You need to manage the equipment, enter the water, and swim with the group. Pregnant people and those with heart disease, diabetes, high or low blood pressure, asthma, respiratory conditions, ear, nose, or throat problems, epilepsy, pneumothorax, pulmonary tuberculosis, or certain medication use cannot participate according to the operator’s rules.
The age restriction is especially important. People over 59 cannot join, and the operator says those aged 60 or above should not reserve. The rule is firm, even for fit swimmers, so check the age requirement carefully before paying.
Is $19.82 a good deal?
At $19.82, this is one of the more affordable guided snorkeling options in Okinawa. Add the 300-yen facility fee and you still receive equipment, insurance, instruction, fish feeding, and underwater images for a modest total cost.
The price is strongest when you are new to snorkeling. Equipment rental alone, a guide, and photographs can quickly cost more elsewhere. The support is also useful if you are traveling with children or have one member of your group who is nervous in the water.
The main limitation is time. The full two-hour window includes preparation and cleanup, while the actual swim is about 45 minutes to one hour. If the cave is crowded or conditions shorten the route, the experience may feel brief.
That is not necessarily a flaw at this price. Think of it as an easy, guided introduction rather than a full-day marine excursion. If you want a long session, detailed reef interpretation, or a quiet cave visit, you may need a more specialized option.
Should you book this Blue Cave snorkeling trip?
I would book it if you are a beginner, a family, or a budget-minded visitor who wants a simple way to see Okinawa’s underwater world. The shallow-water instruction, helpful guides, included gear, fish feeding, and free photos give you plenty for the price.
I would hesitate if you are over 59, have any listed medical restriction, dislike strict schedules, or want a private and quiet experience. I would also choose an early morning departure if possible, and I would accept from the start that the cave may close.
Book this tour for practical fun, not perfect control. You may get the glowing cave, friendly fish, and excellent photos. You may instead get a nearby beach, a crowded swim, and less English than expected. At this price, the experience remains a good buy when you understand those limits.
