Rivering in The Danube (The Mermaid)
The best part of Rivering in The Danube is the change of scene. You leave Cali early and spend the day moving from mountain roads and small-town Colombia to humid rainforest, clear pools, waterfalls, and warm natural tubs. La Sirena, or the Mermaid, is the main prize: a waterfall and swimming spot where you can relax or jump from a rock if conditions allow.
I like two things right away. First, this is a private trip, so your group is not tied to a large bus full of strangers. Second, the day mixes easy local culture in El Queremal with real outdoor activity at the Anchicayá River. The breakfast, lunch, scenery, and helpful guides such as César, Sarita, and Ricardo add good value to the $90 price.
The main caution is the very long day. Pickup is early, the drive takes time, and the river portion includes walking, slippery ground, water crossings, and changing weather. English service must be confirmed before you go, since at least one Spanish-language departure did not have an English-speaking guide.
Key points to know before you book

- La Sirena is the day’s main goal: Reach the waterfall, swim in the pool, or jump from a rock if you feel comfortable and conditions permit.
- El Queremal provides a gentle start: Visit the main park, learn about the local quereme flower, eat breakfast, and walk to the two La Elsa waterfalls.
- The outing lasts 12 to 15 hours: Expect a full day from the Hotel Intercontinental Cali and a return to the same meeting point.
- You will get wet and possibly muddy: Pack a change of clothes, sturdy footwear, and a long-sleeve shirt for the cool early hours.
- The group is private: Only your party takes part, which makes the long day easier to manage at your own pace.
- Language matters: Some departures operate in Spanish, while English-speaking support has been available on other trips. Confirm this clearly when booking.
Leaving Cali before sunrise

Your day begins at the Hotel Intercontinental Cali on Avenida Colombia, normally at a very early hour. The trip lasts about 12 to 15 hours, so this is not a quick afternoon escape. It is a full mountain-and-river day, and you should plan your evening in Cali around a late return.
The early start has one practical advantage: you get out of the city before the day’s main traffic builds. It also means you should prepare the night before. Keep your clothes, water gear, and phone ready, and do not assume you can solve every detail at 5 in the morning.
The drive itself is part of the experience. You move away from Cali toward El Queremal and the Anchicayá area, with mountain views along the route. One particularly useful detail from the trip is that breakfast is served with views toward the mountains, giving you a proper start before the walking begins.
Because this is a private activity, you are not sharing the vehicle or schedule with a large group. That can be a real advantage on a long outing. Your party can ask questions, move together, and avoid the slow loading and unloading that often comes with a big coach.

El Queremal and the two La Elsa waterfalls
The first stop is El Queremal, where the visit begins with the main park and an introduction to the flower called quereme. This is a small but worthwhile local touch. It gives the first part of the day a sense of place instead of treating the area as a simple road stop on the way to the river.
After breakfast, you visit the two waterfalls of La Elsa. The stop lasts about two hours, which gives you time to see the falls without rushing straight through. The waterfalls are a good warm-up for the more active part of the day, though you should not expect a long independent visit. The overall schedule has several stops to fit into one demanding day.
El Queremal also helps break up the long drive. You are not asked to sit in the vehicle for hours before seeing anything. Instead, you get food, a small cultural detail, and an early look at the mountain water system that shapes the rest of the outing.
This section is likely to suit you if you enjoy a day with several short chapters. If you want one long, quiet walk in the forest, the itinerary may feel busy. The value comes from the variety: park, breakfast, waterfalls, river, pools, and a major waterfall all in one day.
Following the Anchicayá River to El Danubio

The second major part takes place around the Anchicayá River and El Danubio creek. You spend roughly three hours in this area, visiting several natural features rather than stopping at only one swimming hole.
The route includes natural hot tubs, the Emerald puddle, the Love puddle, and La Sirena waterfall. The names are playful, but the setting is serious outdoor country. Water levels and clarity can change after rain. One trip found the river less clear after wet weather, yet the forest, pools, and river crossings remained worthwhile.
That point matters. You should not book this as a guaranteed postcard of perfectly clear water every day. The natural setting changes with rainfall, and a recent storm can affect the color and flow. The weather policy reflects this reality: if poor weather cancels the experience, you can take another date or receive a full refund.
At its best, this section gives you a string of small discoveries. You might cross shallow river sections, reach a pool, swim for a while, then continue toward the waterfall. The appeal is not just the final stop. It is the steady change from one water feature to the next.
Reaching La Sirena, the Mermaid waterfall
La Sirena is the centerpiece of the outing. The walk to the waterfall is active but not described as extreme. One account calls it a workout without making it too hard, while another points to steep sections, muddy ground, and the need to remove shoes where the road becomes sticky.
That is a fair way to think about it. You do not need to be a serious trekker, but you should be comfortable with uneven ground and getting wet. The route can include river crossings, slippery surfaces, and a strong incline. Your pace and footing matter more than speed.
When you reach La Sirena, you can swim in the pool and enjoy the setting. If you are confident and the guide says conditions are safe, you may jump from a rock. You do not have to jump. Sitting beside the water or taking a swim is enough to make the stop worthwhile.
I like that the main attraction offers a choice. Some outdoor tours push everyone toward the same activity. Here, you can decide how active you want to be once you arrive. The important thing is to listen to the guide, especially after rain, when water levels and rocks may be less predictable.
Bring a complete change of clothes. This is not just a polite suggestion. The river crossings, wet rocks, swimming areas, and rain can leave you damp long before the ride back to Cali. A plastic bag for wet clothing would also be sensible, though it is not listed as a supplied item.

Food, guides, and the personal feel of a private trip
Breakfast and lunch are part of the day’s appeal. The food has received especially positive attention, and the meals help justify the long schedule and $90 price. You are not paying only for a ride to a waterfall. You are also paying for transport, guiding, several stops, and food across a full day.
The guides named in the experience include César, Sarita, and Ricardo. César has helped with transport coordination and suggestions for other places to stay or visit in Cali. Ricardo is associated with the river outing and has been singled out as a strong guide. Sarita has also worked with César on the walk to the Oasis de la Sirena.
I would treat the guide names as examples rather than a guarantee of who will lead your departure. Still, they give you a useful point of reference when communicating with the operator. If a particular language or guide is important to you, ask before payment.
The private format is one of the strongest features here. A small group makes river crossings and swimming stops less awkward, and it gives the guide a better chance to keep track of everyone. It also means the experience can feel more like a day out with a local team than a standard sightseeing transfer.
There is one language issue you should handle carefully. Some departures are in Spanish, and one Spanish-language trip had no English-speaking guide. Other departures have had English support. Confirm the language in writing before you go, and make sure you understand the pickup arrangement. This is especially important because the pickup is very early.
What to pack for the mountain and river

The clothing advice is simple but important. The early hours at higher elevation can feel cool, even if Cali later feels hot. Pack a long-sleeve shirt for the morning and light clothing that can dry after the river section.
You should also bring:
- A full change of clothes
- Shoes that can handle mud and wet ground
- A towel, if you have room
- A waterproof bag for your phone and documents
- Drinking water and any personal snacks you need
- Sun protection for exposed sections
The information provided does not specify that towels, special water shoes, or waterproof bags are supplied. Plan as if they are not. You will have a better day if you can keep your phone and spare clothes dry.
Do not wear footwear that you cannot get dirty. The road and forest route may be muddy, and some sections can be easier barefoot or with shoes removed, depending on the guide’s instructions. That does not mean you should walk unprotected for long stretches. It means conditions can require flexibility.
Is $90 a good value?
At $90 per person, this is not the cheapest way to see nature near Cali, but the price makes more sense once you look at the day as a whole. You get hotel pickup and return from the stated meeting point, private transport, a full-day schedule, breakfast, lunch, guiding, and access to several river features.
The value is strongest for people who want everything arranged. Organizing transport from Cali to El Queremal, then to the river area, then back to the city would take time and local knowledge. The private format also costs more than a large shared outing, but it gives you a quieter and more flexible experience.
You should not judge the price only by the time spent at La Sirena. The day includes the journey, El Queremal, La Elsa, Anchicayá, El Danubio, the pools, and the final waterfall. If you only want a short swim, this is too much day for the goal. If you want a full countryside experience, it is a reasonable package.
The outing is often booked about 28 days ahead, so leaving it until the last minute may not be wise. Free cancellation is available up to 24 hours before the start time. Changes made inside that period are not accepted, and poor weather can lead to a different date or a full refund.
Who should book this river day?
I would recommend it to you if you enjoy active sightseeing, do not mind a long day, and want more than a single viewpoint. It suits couples, friends, and private groups who are happy to walk, swim, cross water, and get muddy in exchange for a strong natural setting.
It also works well if you want a guide handling the complicated parts. The route involves early transport, mountain roads, several stops, and outdoor conditions that may change. Having a local team manage the day removes much of the planning burden.
This is less suitable if you dislike early starts, have trouble walking on slippery ground, or want a predictable weather-controlled schedule. The tour requires good weather, and the trip can be affected by rain. If you need guaranteed English, settle that point before booking rather than hoping it will work out at pickup.
Most people can participate, and service animals are allowed according to the activity details. Still, the stated physical demands deserve attention. The trail can be steep or muddy, and the swimming and jumping portions are optional but take place in a natural setting, not a managed pool.
Should you book Rivering in The Danube?
Book it if you want to spend a full day outside Cali and prefer a private, guided route over arranging several transfers yourself. The combination of El Queremal, La Elsa, Anchicayá, natural pools, and La Sirena gives you a lot for one day, and breakfast and lunch make the price easier to defend.
Before paying, confirm the guide language, pickup time, what food is included, and the expected walking conditions. Then bring dry clothes, a long-sleeve shirt, and shoes you can sacrifice to the mud. If you accept the long hours and changing river conditions, this is a memorable way to see the wet mountain country beyond Cali.
