Halloween is the one night of the year when Paris fills up with people in costume and nobody finds it strange. It is also one of the worst organised nights of the year, because everyone starts looking on October 28 for a date that needs booking in early October. Here are the formats that actually work with a group, what they cost, and when you need to commit.
Three families of plans, and nothing else
Everything happening in Paris on October 31 fits into one of these three boxes.
The costume party, in a club, a bar, a vaulted cellar or on a boat on the Seine. This is the classic format, the one that produces the best photos and the worst queues. The costume is often a condition of entry, not an option.
The group activity, done together before the party or instead of it. Action game, horror escape room, murder mystery party, shooting bar, board game bar. Nobody needs a costume, the atmosphere comes from the game, and the group stays together from start to finish.
The theme park after-dark event, outside the city. The most spectacular format, the most expensive and the longest in travel time. It gets decided three weeks ahead, not on the day.
Every other idea you will read about elsewhere is a variation on these three.
Comparing the formats
| Format | Ideal group | Costume | Budget per person | Book by |
|---|---|---|---|---|
| Club or bar costume party | Unlimited | Often mandatory | €15 to €30 entry, drinks extra | 2 to 3 weeks |
| Action game or escape room | 2 to 6 per team | Not needed | €28 to €45 | 3 to 4 weeks |
| Shooting bar or board game bar | 2 to 10 per booth | Not needed | From €16 | 3 weeks |
| Murder mystery party | 8 to 30 | Encouraged | Varies by organiser | 1 month |
| Theme park after-dark event | Unlimited | Optional | Ticket + travel | 3 weeks |
| House party | 6 to 20 | Optional | The price of the shopping | The day before |
Group activities, the plan that saves mixed groups
This is the most underrated option, and the one that solves the most problems at once. No costume requirement, a price you know in advance, and an evening with a clear beginning and end instead of one that drifts away in a queue.
The action game is the format best suited to large, mixed groups. Inside Paris, Bomb Squad runs this format on boulevard de Sébastopol in the 3rd arrondissement, in teams of 2 to 6 players for one hour of play, with staggered start times that let up to 60 participants go through over a two hour window. The rate is degressive, from 45 euros per player for two down to 28 euros for six, and the activity is open from age 7. It is the right choice when the group includes people who are not naturally competitive, because nobody ends up watching from the side.
The shooting bar plays on the same register of adrenaline, with food and drinks on site, which avoids the 9pm move that always loses three people along the way. PAN Bar, in the 10th arrondissement, works with booths of 2 to 10 people from 16 euros per person, up to 66 players across several booths, and privatises its 400 square metres from 30 people upwards. Note that the venue is closed on Mondays.
The horror escape room remains the reflex Halloween booking, and it is also the category that sells out fastest in late October. If you are starting late, look at neighbouring formats, our comparison of alternatives to escape rooms covers what comes closest in terms of adrenaline.
The murder mystery party is the most underrated format on the list. An investigation, assigned roles, costumes welcome without being mandatory, and a mechanic that forces people to talk to each other. It works from eight people upwards.
The events that come back every year
A few large formats return at roughly the same dates each autumn, give or take a day or two. The exact dates change every season, so check them before committing to anything.
- Peur sur le Parc, at Parc Astérix, runs each autumn from early October to early November, with a dozen after-dark sessions running until 1am. It is the most intense format in the Paris region, with scare zones reserved for the bravest.
- The Halloween Festival at Disneyland Paris runs from late September to November 1, family friendly during the day and more spectacular in the evening.
- The Jardin d’Acclimatation stages a Halloween and Día de los Muertos programme every autumn, colourful rather than frightening, which suits groups with children.
- The large electronic music nights on the outskirts, such as Dream Nation in Seine-Saint-Denis, run across the nights of October 30 and 31, with festival scale capacity and hours.
- The City of Paris publishes an official selection of parties for the night of October 31 each year, useful for spotting the venues that take it seriously.
Halloween with colleagues, the team version
October 31 falls just before the corporate party season, which makes it a good excuse for a more structured after-work than usual, without waiting for December and its saturated calendars.
The format that works comes in two parts, a one hour to ninety minute activity at the end of the day, then free time at the bar on site. Three things to check before booking, the real simultaneous capacity rather than the total capacity of the venue, whether there is proper food, and how exposed the chosen format leaves people. One person uncomfortable in front of the group is enough to flatten the mood. Our guide to organising a team building event breaks down the budget tiers by team size, and the same logic applies to a more festive after-work.
When to book, realistically
The calendar drives everything, and it hangs on a detail nobody checks, the day of the week October 31 falls on.
When it falls midweek, the party naturally moves to the nearest weekend, which spreads demand across three evenings and loosens availability. When it falls on a Friday or a Saturday, everything concentrates on a single night, prices rise and evening slots go three to four weeks ahead.
Either way, activities that run on time slots or booths sell out before the clubs do, because the number of sessions per evening is mechanically limited. If your group is larger than ten people, treat October 10 as the real deadline.
The classic mistakes
- Booking a club without reading the costume rule. Some venues turn away anyone not in costume on October 31, and you find out on the pavement.
- Planning a theme park night without checking the last train. An event ending at 1am outside the city turns into a shared taxi, and the budget doubles.
- Choosing a high adrenaline format for a group that has barely spoken. Not everyone wants to be chased by an actor in make-up.
- Stacking two plans in one evening. An activity followed by a club works if the two are less than fifteen minutes apart, otherwise the group scatters in transit.
Where to find this year’s parties
Halloween parties are announced late, often only three to four weeks ahead. Ticketing platforms and the City of Paris listings publish first, then bars and clubs announce on their own channels. Activity venues, on the other hand, open their slots much earlier, which is one more reason to start there.
For the rest of the year, our selection of unusual activities in Paris and our overview of bars and games venues cover the same needs without the date constraint.
