Review · BLUE HOLE & SECRET FALLS TOURS
From Foz do Iguaçu: Secret Falls Adventure
The best part of this Foz do Iguaçu outing is simple: you trade the big viewing platforms for five smaller waterfalls and swimming spots in the forest. The water, natural pools, and subtropical plants give you a closer look at the Iguazu region than a standard sightseeing stop.
I like the small maximum group of 15, which gives the guide room to explain the forest and help on the trail. I also like the mix of easy and medium walks, plus the chance to swim in a natural jacuzzi. The main drawback is that the day is not a tight, fixed schedule. It can last anywhere from five to eight hours, and transport arrangements need careful confirmation.
Key things to know before you go

- Five waterfall stops: You get several chances to see and swim near falls, rather than one quick viewpoint.
- Natural pools and a jacuzzi: Bring clothing that can handle a swim, since the water is a central part of the outing.
- Small groups: The maximum is 15 people, with travel by car or van based on group size.
- Easy and medium trails: No trekking background is required, but this is not a good fit for limited mobility.
- Guides in three languages: Portuguese, Spanish, and English are available, with guides such as Kauano, Andrés, and Camili named in guest feedback.
- Bring identification and sturdy shoes: A passport or ID card and comfortable footwear are required essentials.
Five waterfalls instead of one big spectacle

Foz do Iguaçu is famous for the huge Iguazu Falls, but this experience takes a quieter route. You visit five waterfalls in a forest setting, with time for swimming and walking between stops. That changes the feel of the day. You are not simply looking over a rail, taking a picture, and moving on.
The waterfalls are described as part of the Iguassu Secret Falls area. The attraction is the combination of flowing water, forest paths, and natural pools. You may find one stop better for photos and another better for a swim, but the appeal is the variety.
I like this format for a second or third day in Foz do Iguaçu. The major falls are a must, but they can feel grand and busy. This outing gives you a more hands-on nature experience. You can hear the water at close range, walk through subtropical growth, and spend time in places that are set up for a slower visit.
Do not expect five giant versions of the main Iguazu Falls. The word secret refers to smaller, less obvious waterfall sites, not to another massive cataract. The value lies in the access and the chance to get wet, not in matching the scale of the national park views.

Leaving Rua Manêncio Martins by car or van

The day begins at Rua Manêncio Martins. From there, the drive to the waterfall area takes about 30 minutes. Transport is by car or van, depending on the group size, and the maximum group is 15 people.
That half-hour transfer is useful because the outing begins without a long road journey. It also means you should sort out your meeting details in advance. The information provided says transportation to the local area is not included, while regular transport back to the hotel is available only in the afternoon. Those two details make the start and end arrangements worth checking carefully.
The exact schedule is flexible. The stated five to eight hour duration is a range, not a promise that every group will follow the same clock. The reservations department is expected to confirm the schedule the day before, so keep your morning or afternoon open rather than booking another fixed activity too close to this one.
I would also avoid assuming that your hotel pickup is automatic. Since transport wording distinguishes between getting to the local area and returning to the hotel, confirm where you need to meet the group and how the afternoon return works.
Walking through the subtropical forest

Once you reach the waterfall area, the main activity is on foot. The guide leads you along an interpretive rainforest trail, pointing out local wildlife and tropical plants along the way. The forest is not just scenery between waterfalls. It is part of the experience.
The trails range from easy to medium level, so you do not need previous trekking experience. Still, medium-level paths can involve uneven ground and a steady amount of walking. Comfortable shoes are listed as essential, and I would take that seriously. This is not a flip-flop sightseeing stop.
The guide’s role matters here. A walk through thick plant life can become a blur of green if nobody explains what you are seeing. A good guide gives the forest some meaning, helps you move safely, and keeps the pace friendly. Specific guides praised for this kind of care include Kauano, Andrés, and Camili. One English-speaking guide, Kauano, was singled out for being helpful, fun, kind, and easy to understand. Andrés was praised for making the route feel safe and unhurried, while Camili added information about local fauna.
Guide quality can vary by departure, of course, but the multilingual setup is a real advantage. You can select Portuguese, Spanish, or English, which makes safety instructions and nature explanations much easier to follow.
Swimming in clear pools and the natural jacuzzi

The swimming stops are what set this outing apart from a normal forest walk. You can stop at five waterfalls, swim in clear natural pools, and use a natural jacuzzi formed by the moving water. The experience is active, but it is not built around a hard physical challenge.
You should expect wet feet and wet clothing. The supplied information does not list changing rooms, lockers, towels, or rental swimwear, so pack only what the operator specifically requires and do not assume those extras are available. Food and drinks are also not included. Bring any permitted refreshments you need, while remembering that the activity information does not promise meal stops.
The natural jacuzzi is a fun detail, but the water environment still calls for care. Follow the guide’s instructions, especially around rocks and currents. Safety equipment and water were made available on at least one afternoon outing, but those items are not clearly promised as standard inclusions for every departure. Ask what will be supplied when you confirm the time.
A swim can also change the length of the day. Groups may spend more or less time at each fall depending on conditions, pace, and the schedule. That helps explain the broad five to eight hour range.

What the $65 price really covers

At $65 per person, this is a reasonable price if you want a guided nature outing with transport during the activity and entrance to the waterfall area. The tour ticket is included, and you get professional guidance in a small group. Those are the parts that save you from having to arrange access and navigate the trails alone.
The price is less complete than a full-day package. Food and drinks are extra. Transportation to the local area is not included, and the included return transport is described as hotel transport in the afternoon. If you need a private transfer, a morning hotel pickup, or meals, confirm the added cost before booking.
The value is strongest for people who care about access and guidance. You are paying for five waterfall stops, a forest walk, swimming opportunities, and a guide who can explain the setting in your language. If you only want a quick waterfall photo, a cheaper public attraction may suit you better. If you want to spend several hours in the forest and water, the price makes more sense.
There is also useful flexibility in the booking terms. You can reserve now and pay later, and cancellation is free up to 24 hours before the activity for a full refund. Those terms help if your Foz do Iguaçu plans are still shifting, but they do not remove the need to confirm the daily schedule.
How the five to eight hour day unfolds
The route is straightforward, even if the timing is flexible:
- You meet at Rua Manêncio Martins.
- You travel about 30 minutes by car or van.
- You enter the Iguassu Secret Falls area for a guided walk, sightseeing, and swimming.
- You return by car or van, with the regular hotel return offered in the afternoon.
- You finish in Foz do Iguaçu.
The middle section is the heart of the day. The guide leads you along the trail, introduces the plants and wildlife, and brings you to the five waterfalls. The exact order and amount of time at each stop are not given, so you should not plan around a precise waterfall-by-waterfall timetable.
The flexibility is helpful for a nature outing. A group can spend a little longer at a good swimming spot or move on if the pace is slower. The tradeoff is that you cannot count on a precise finish time. Leave a cushion before dinner, an airport transfer, or another timed attraction.
Who will enjoy this most
I would choose this for an active couple, a small family with older children, or anyone who wants more contact with nature than a standard viewpoint provides. It suits people who enjoy walking, can manage easy to medium trails, and are happy to swim outdoors.
It is also a good choice if you want a guide who can add context. The best part is not only reaching the water. It is learning what you are seeing and moving through the forest with someone who knows the route.
This is not suitable for pregnant women, people with back problems, or people with mobility impairments. It is also not recommended for anyone with limited mobility. The walk may be rated easy or medium rather than advanced, but that does not make it accessible to every body.
Smoking and pets are not allowed. Bring a passport or ID card, even if you are traveling within Brazil, since identification is listed among the required items.
The guide can shape the whole experience
A small nature tour depends heavily on the person leading it. A rushed guide could turn the trail into a transfer between pools. A patient guide can make the same route feel like a proper forest outing.
The strongest guide details available are worth noting. Kauano was praised for speaking excellent English and for being helpful, kind, and good company. Andrés was described as making the walk safe and relaxed while sharing a strong understanding of the forest. Camili provided information about local fauna and helped make an afternoon route memorable.
You cannot guarantee a particular guide unless the operator confirms it. Still, the named examples show what to look for: clear safety help, a manageable pace, and explanations about the forest rather than only directions to the next fall.
The tour is offered in Portuguese, Spanish, and English. If language matters to you, state your preference when booking and confirm it the day before.
Practical packing advice for a wet forest day
Keep your packing simple and useful:
- Passport or ID card
- Comfortable shoes with a secure fit
- Swimwear and a change of clothes
- Water and food, since neither is included
- A small bag for wet items
- Sun and rain protection if needed
Only the first two items are specifically required, so the rest is practical advice rather than a promise of what the operator provides. Water and safety equipment were available on one reported afternoon outing, but I would still confirm what comes with your departure.
Do not bring a pet or plan to smoke during the activity. Also, avoid carrying more than you can manage on the trail. You will be walking, stopping near water, and getting in and out of a car or van.
Should you book the Secret Falls Adventure?
Book it if you want a small-group forest outing with five waterfall stops, natural swimming pools, and a guide who can explain the plants and wildlife. At $65, it offers good value for several hours of guided access, especially if swimming and a close-to-nature setting matter more to you than a fixed timetable.
Think twice if you need a fully accessible route, a guaranteed short day, included meals, or simple door-to-door transport. The flexible five to eight hour schedule and transport wording require a little planning.
For most active visitors with time beyond the main Iguazu Falls, I would consider this a strong addition. Confirm the meeting point, return transport, language, and what water equipment is supplied. Then bring comfortable shoes and leave room in your day for the forest to set the pace.
