The Butte aux Cailles swimming pool displays its hours on the City of Paris website, but the actual swimming time does not match the announced time slot. Between the last swimmer admission, the gradual evacuation of the pools, and the slots reserved for schools or clubs, the discrepancy can reach nearly an hour on certain half-days. Before heading to Place Paul-Verlaine, it’s important to understand these mechanisms.
Butte aux Cailles Pool: the discrepancy between displayed hours and actual swimming time
The paris.fr website indicates an opening time and a closing time for each public slot. What most swimmers do not read (or read too late) are the three rules that reduce this window.

- Last swimmer admission: 45 minutes before closing. If the session ends at 5 PM, no one is allowed in after 4:15 PM. A swimmer arriving at 4:20 PM will be denied access, even if there are still people in the water.
- Evacuation of the outdoor pool: 45 minutes before closing. Therefore, the Nordic pool closes at the same time as the admission stops, leaving no margin for those who were counting on a last swim outdoors.
- Evacuation of the indoor pool: 30 minutes before closing. Only this covered pool offers an additional quarter-hour compared to the outdoor pool.
In practice, a displayed two-hour slot is reduced to about an hour and a quarter of actual swimming if you arrive at the opening time. If you arrive in the middle of the slot, the available time decreases even faster.
This operation is not unique to Butte aux Cailles: all municipal swimming pools in Paris apply these rules. However, the impact is more noticeable here because the public slots are already short, interrupted by school and association reservations.

To anticipate the crowd at Butte aux Cailles pool and avoid a wasted trip, it’s better to check the exact slot for the day before leaving, as the schedule changes depending on the periods.
Reserved slots and variable schedule: what further reduces public access
Parisian swimming pools are not continuously open to the public. At Butte aux Cailles, a significant part of the day is allocated to schools in the 13th arrondissement and approved sports associations.
Specifically, weekday mornings are rarely accessible to the public outside school holidays. Public slots are concentrated in the early afternoon and late in the day, with variations depending on the day of the week.
A schedule that changes depending on the period
The hours published online are not fixed for the entire year. The City of Paris publishes separate schedules for school time, short vacations, and summer vacations. A slot open to the public in July may be removed in September, and vice versa.
Supervised activities like aqua jogging also occupy certain pool slots, reducing the capacity available for free swimming even when the facility is officially open to the public. These dated sessions are published by the City, but are rarely consulted by occasional swimmers.
The detailed schedule is downloadable in PDF format on the paris.fr page of the facility. Checking it each week remains the only reliable way to know the actual hours.
Unexpected closures at Butte aux Cailles pool: the SMS alert service
Last-minute technical closures (water treatment failure, heating problem, urgent maintenance) do not always appear on the website before swimmers have already traveled there. This is a recurring point of friction, documented by feedback from users in the 13th arrondissement.
The City of Paris has set up an SMS alert service that notifies subscribers in case of unexpected closure of their pool. Registration is done via an online form accessible from the facility’s page on paris.fr.
This service only covers unscheduled closures. Changes to the schedule related to school holidays or municipal events do not trigger an alert. It complements the consultation of the schedule, without replacing it.
Outdoor pool and indoor pool: two different evacuation logics
Butte aux Cailles has three pools: a covered pool, an outdoor Nordic pool, and a wading pool. What distinguishes this facility from most Parisian swimming pools is the coexistence of an outdoor pool and an indoor pool, each subject to distinct evacuation rules.
The outdoor pool closes 45 minutes before the displayed time, while the indoor pool closes 30 minutes before. A swimmer arriving mid-slot thinking they can alternate between the two may find access only to the covered pool, as the Nordic pool is already in the process of evacuation.
In winter, the constraint increases
The pools are heated year-round, but attendance at the outdoor pool remains dependent on weather conditions and possible seasonal closures for maintenance. Summer and winter hours differ significantly, with public slots often more restricted between October and March.
The available data does not allow for a fixed calendar for these adjustments, as they vary from year to year depending on maintenance budget and community decisions.
Butte aux Cailles Pool: summary of time constraints to check
Before heading to Place Paul-Verlaine, three checks reduce the risk of unnecessary travel: consult the current week’s PDF schedule on paris.fr, register for the SMS alert service, and calculate the actual swimming time by subtracting the evacuation margins from the displayed time.
A two-hour slot offers about an hour and fifteen minutes of effective swimming. This simple calculation avoids disappointment on-site, especially for swimmers who do not regularly visit Parisian municipal pools. The rest depends on the day, the season, and the slots reserved for schools or supervised activities.
