In one sentence: we work with an open Premium window from 10:30 am to 12:30 pm for arrival at our office in Arriondas, and the river always closes at 6 pm by order of the Confederación Hidrográfica. Inside that, the Mini can launch right up to the last minute of the window; the Full is best started between 10:30 am and 11:30 am so you can paddle at an easy pace.
This is one of the questions we get most by WhatsApp: "what time do we have to be there?". The answer is not an exact number — it is a time window designed so you experience the river without rushing. Below: our open Premium window 10:30 am to 12:30 pm, the legal timings of the river and, above all, what time it suits you to set off by route (Mini at 2-3 h or Full at 4-5 h).
We have spent more than 25 years taking families down the Sella from Arriondas (Asturias), so this guide is written from real practice: what avoids the rush and what lets you enjoy the river without watching the clock.

Quick summary: the timetable on one tab
If you only have 30 seconds before booking, take this with you:
- Arrival at the base (Arriondas): between 10:30 am and 12:30 pm (open Premium window, no exact time to choose).
- Launch onto the water: when your group is kitted out and ready, inside that same window.
- River closure by the Confederación Hidrográfica: 6 pm. Every craft must be off the water by then.
- Pick-up at the finish + transfer back to Arriondas: about 20 minutes by coach.
- Mini (7 km · 2-3 h on the water): you can comfortably launch right up to 12:30 pm.
- Full (14.5 km · 4-5 h on the water): better to launch between 10:30 am and 11:30 am. We do not recommend starting it after 1 pm.
Step by step below, with the nuance of each route and the special days of the summer.
Is this the best time or the available timetable?
You may have landed here looking for one thing and finding another. Quick clarification:
- What is the best time of day to paddle the Sella? talks about strategy: early or midday, how to avoid the busiest hours, what time suits each month (busy July vs quiet June), light, water temperature, photographs…
- This post talks about operations: what time windows exist for boarding, when to be at the base, when to launch by route to reach the pick-up on time, and what legal restrictions the river sets.
In short: "what time do I set off so I have enough time" → this post. "What is the best moment of the day to experience it" → the other one. The two complement each other; they do not overlap.
Our Premium open slot: 10:30 am to 12:30 pm arrival window
Unlike operators that assign you a fixed time (11:00, 12:00, 1:00 pm…), at Aventura en el Sella we work with an open Premium window: you arrive at our base in Arriondas whenever you can between 10:30 am and 12:30 pm, we kit you out without queues (life jacket, paddle, canoe, safety briefing) and you launch as soon as your group is ready.
We do it this way because we do not like rushing. The open window solves three things:
- Real margin: if you hit traffic near Ribadesella or the sat-nav takes a wrong turn, you have until 12:30 pm without losing the activity.
- No crowding queues: by spreading arrivals across two hours, you avoid the bottleneck of "everyone at 11:00".
- We launch at your group's pace: when your family has the right footwear on, is hydrated and has the life jacket properly fitted, then you set off.
Inside the window you do not need to choose a time. You book your Mini or your Full and you turn up whenever it suits you. If you arrive at 10:35, perfect. If you arrive at 12:25, perfect too.
The clock that does run: the river closes at 6 pm
Here comes the only non-negotiable rule of the Sella. The Confederación Hidrográfica del Cantábrico regulates recreational navigation and rules that, during the season, every craft must be off the water before 6 pm.
It is not a rule of our company. It is the rule that applies to every operator on the river, and it sets the latest time you can launch depending on your route. The longer the descent, the earlier it suits you to start. If you are curious about the real tiredness of each route, we break it down in is the Sella descent tiring?.
Add a practical detail: once you step out of the water at the pick-up point (Toraño for the Mini, Fríes for the Full), there is still the coach transfer back to Arriondas, about 20 minutes. By default the coach drops you at the office so you can shower and change calmly; if you would rather go straight to the car at the boarding car park, just ask the instructor on the transfer. Count it as part of the day, not an extra.
Mini (2-3 h): what time to set off
The Mini route (7 km, finishing at Toraño) is the most relaxed: 2 to 3 hours on the water, with time for swims, a stop at a riverside snack bar and unhurried photos. From €25 children 5-12 / €35 adults · pets free, all inclusive.
- Ideal launch: 11:30 am - 12:30 pm (any moment inside the Premium window works).
- If you launch at 12 noon: you reach Toraño around 2:30 - 3:00 pm. A lovely late lunch, and back in Arriondas around 3:30 pm.
- If you launch at 12:30 pm (last boarding): you reach Toraño around 3:00 - 3:30 pm. No problem at all with the river closing time.
The Mini is perfect because it gives you margin even if you leave home late. If you are torn between the short or the long route, our guide on how long the Sella descent takes will help you decide.
Full (4-5 h): what time to set off
The Full route (14.5 km, finishing at Fríes) is the classic descent: 4 to 5 hours on the water, not counting stops. Here the timetable does matter and it is worth planning carefully. You have the interactive route and map with every landmark.
- Ideal launch: 10:30 - 11:30 am.
- If you launch at 11:00 am: you reach Fríes around 3:30 - 4:00 pm. A rounded afternoon.
- If you launch at 12 noon: you reach Fríes around 4:30 - 5:00 pm. Tight, with no long stops.
- If you launch at 12:30 pm (last boarding): you reach Fríes around 5:00 - 5:30 pm. Very tight. Only if you are paddling at a good pace and not making long stops.
Honest recommendation: if you are doing the Full, do not launch after 1 pm. The 6 pm closure leaves you out of breath, no time for stops at the bars and forces the children's pace.
If you arrive late and only the Mini fits the time, we will tell you at the base. We would rather do that than put you into a Full against the clock. For families with little ones or groups with a dog, the Mini wins almost every time because of pace and stops.
Exceptions: when the timetable changes
Two scenarios where the usual timetable does not apply as is:
International Sella Descent · Saturday 8 August 2026
On the day of the International Sella Descent, the river is reserved for several hours for the official competition (start from the Arriondas bridge around 12 noon). All operators adapt the tourism timetable to the race.
If you want to paddle on the same day as the International, drop us a line first and we will confirm the specific window for that Saturday (the river usually reopens to tourism later in the day, once the race is over). For the full backdrop, read the history of the Sella descent since 1929.
Storms or high flow
If the Confederación Hidrográfica detects abnormally high flow, storms or risk, they can:
- Shorten the window for navigation (for example, open only from 11:00 am to 4:00 pm).
- Assign fixed launch times instead of an open window.
- Close the river temporarily (we notify by WhatsApp and reschedule at no cost, according to our cancellation policy).
It is very unusual in season (May to October), but if your date falls on a day with a bad forecast, we ring you from the base. To pick the moment with the lowest risk of storms, have a look at the best time of year for the Sella descent.
How to plan your full day
So the timing piece slots together without stress, here is a full-day outline (valid for Mini and Full):
- 9:30 - 10:00 am. Leave your accommodation (if you are staying in Cangas de Onís, Ribadesella, Llanes…). If you have not booked a hotel yet, our guide on where to stay near the descent will help.
- 10:30 am - 12:30 pm. Arrival at the office in Arriondas (Calle Juan Carlos I, 18 Bajo II) for check-in, payment if applicable and to collect life jacket and watertight barrel. Changing rooms and lockers are here. Then on to the boarding car park across the river (free · 300 spaces · motorhomes welcome).
- 15-20 min. Kitting out + safety briefing at the boarding area. We show you how to handle the paddle and read the two small rapids at the start. Knowing how to swim is mandatory by law for everyone, including children.
- Variable. Descent down the river with optional stops at the riverside bars and river beaches along the route.
- Toraño / Fríes. Pick-up point depending on route.
- ~20 min. Coach transfer back to Arriondas.
Before 6 pm you are off the water, always. Before 6:30 pm (give or take) you are showered and changed at the base. From there, the day is yours: cider in Arriondas or drive over to Ribadesella to round off the afternoon on the beach.
If your little one is around the minimum age of 5 years old and 1.15 m, it suits you to launch early (10:30 - 11:00 am) and choose the Mini. Children do better with the fresh morning and still have plenty of margin for unhurried swims. We go deeper into it in Sella descent with small kids.
What time should I book?
If you have it clear, book online here and we confirm in minutes. If you are torn between Mini or Full depending on what time you can arrive, drop us a line by WhatsApp, phone or email and we will guide you with no strings from our base in Arriondas. The contact details are on their page. A prior booking is always recommended; same-day is possible if there is availability in our calendar.

What you ask us most
- What exact time do I need to be in Arriondas?
There is no exact time. We work with an open Premium window from 10:30 am to 12:30 pm: you turn up whenever it suits you inside those two hours and we set off onto the river as soon as your group is kitted out. That is the timetable we offer under normal conditions (no storms, no special event).
- Can I set off onto the river after 1 pm?
For the Mini (2-3 h), yes, as long as it is inside our window up to 12:30 pm. For the Full (4-5 h) we do not recommend it: the river closes at 6 pm by order of the Confederación Hidrográfica and setting off late forces you to paddle against the clock. If you arrive after 12:30 pm and were planning the Full, it is better to switch to the Mini.
- Why does the Sella River close at 6 pm?
Because the Confederación Hidrográfica del Cantábrico regulates recreational navigation on the Sella and rules that every craft must be off the water before that hour. It is a common rule for every operator working on the river, not a decision of ours.
- How long does the coach transfer back to Arriondas take?
About 20 minutes by coach from the pick-up point (Toraño for the Mini, Fríes for the Full) back to our base in Arriondas. Always factor that into your day so you reach the showers and the car with a comfortable margin.
- And on the day of the International Sella Descent?
On Saturday 8 August 2026 the river is reserved for several hours for the official competition. You can still paddle that day, but with an adapted timetable. Drop us a line to confirm the exact slot and, if you want the full experience of the International Descent, we will tell you how to enjoy it from the riverbank.
