The Butte aux Cailles swimming pool, located in the 13th arrondissement of Paris, has public time slots that vary depending on the pool, the day of the week, and the school period. Understanding these variations allows visitors to target times when attendance is manageable and those when the queue makes swimming less worthwhile in terms of time.
Weekly Schedule by Pool: Three Grids to Read, Not Just One
Most visitors check the overall schedule on the City of Paris website. This grid provides a simplified view that masks a more fragmented reality. The Butte aux Cailles operates with a separate weekly PDF schedule for each pool: indoor, outdoor Nordic, and children’s wading pool.

A time slot marked as “open to the public” may only apply to one of the three pools. The other two are then reserved for school groups or swimming clubs. Consulting this PDF before heading out avoids unpleasant surprises, especially during school periods when group reservations occupy a significant portion of the swimming lanes.
To follow the hours and attendance at the Butte aux Cailles pool in real-time, the intersection between the weekly PDF and user feedback remains the most reliable method.

| Pool | Last Swimmers’ Admission | Pool Evacuation |
|---|---|---|
| Indoor Pool | 45 min before closing | 30 min before closing |
| Outdoor Nordic Pool | 45 min before closing | 45 min before closing |
| Children’s Wading Pool | 45 min before closing | 45 min before closing |
The gap between the two columns shows that the outdoor pool empties a quarter of an hour earlier than the indoor one. A public time slot marked “open until 7 PM” no longer allows swimming outside after about 6:15 PM, which radically changes the calculation for those coming specifically for the Nordic pool.
Attendance at the Butte aux Cailles Pool: The Time Slots That Make a Difference
The time slot 12 PM to 2 PM has the longest queues, sometimes exceeding thirty minutes. This peak is explained by the lunch break of local workers and the release of the pools after the morning school slots.
In contrast, two windows offer significantly lower attendance:
- The early morning opening, before the arrival of school groups, where the swimming lanes remain fluid for about an hour
- The late afternoon on weekdays, after the school groups leave and before the evening swimmers arrive
- The evening slot, when it exists, which attracts a smaller and more regular audience
The weekend changes the situation: the absence of school slots frees up more swimming lanes, but family attendance largely compensates, especially in the outdoor pool as soon as temperatures are mild.
Heatwave Protocol and Occasional Closures: What Changes in Summer
Since recent heat episodes, the City of Paris has implemented a specific protocol in case of an orange heatwave alert. This protocol has a direct impact on the swimming experience at Butte aux Cailles.
Three measures concretely alter access conditions:
- Closure of the solariums from 12 PM to 4 PM, which removes the outdoor relaxation space during the hottest hours
- Cancellation of intense aquatic activities, including aquagym, during the alert period
- Massive redirection of attendance to the indoor pool, even when the official schedule does not change
The last point is the most misleading. The displayed hours remain the same, but the actual attendance at the indoor pool increases significantly due to transfer effects. Swimmers who came for the outdoor pool or the solarium shift to the covered space, creating an invisible saturation not reflected in the schedule.
School Period or Holidays: Two Different Pools
The distinction between school periods and school holidays transforms the operation of the pool. During school weeks, a significant portion of morning and early afternoon slots is reserved for schools in the district. The indoor pool absorbs most of these sessions, sometimes leaving the outdoor pool accessible to the public, but with a reduced number of lanes.
During holidays, these reservations disappear. The public hours expand, and all three pools are more often open simultaneously. The downside: families with children heavily occupy the wading pool and the Nordic pool, which can lengthen the wait at the entrance despite the absence of school groups.
The summer period combines two effects. On one hand, opening hours are generally extended. On the other hand, the Butte aux Cailles pool, with its outdoor pool heated by a geothermal source, attracts visitors well beyond the 13th arrondissement. On hot days, the queue can form as soon as the pool opens.
Rates and Access: What Standard Grids Don’t Specify
The entrance fee follows the Paris municipal grid. Discounts are available for Paris residents and regular users through multi-entry cards. The detailed pricing information is available on the official City of Paris sheet.
A rarely mentioned point: access to the outdoor pool is not guaranteed by the entrance ticket. If this pool is reserved for a club or closed for maintenance, the ticket remains valid only for the indoor pool. No partial refund is provided in this case, which justifies checking the PDF schedule before heading out.
The combination of a fragmented schedule by pool, a heatwave protocol that alters attendance without changing the hours, and marked seasonality makes Butte aux Cailles a pool where advance preparation directly affects the quality of the session.
