If the forecast says rain on the day of the birthday party, you don't have to cancel anything: Catalonia has plenty of covered places. According to our data, 246 of the 372 venues in the catalogue are indoor and another 26 combine indoor and outdoor space. What matters is having a plan B ready before the storm arrives, and knowing what to ask the venue.
Which kind of indoor venue to choose
It depends on the children's ages and how many are coming. Here are the most common options and what a party for 15 children typically costs in total, based on data from how the site works (indicative prices from the venues' own websites on 23/10/2026; always check with the venue):
| Type | Venues with a price | Median total (15 children) |
|---|---|---|
| Indoor play centres | 22 | €225 |
| Trampoline parks | 14 | €240 |
| Bowling | 6 | €203 |
| Escape rooms | 23 | €255 |
| Arts and crafts workshops | 5 | €280 |
| Ludotecas and kids' clubs | 61 | €100 |
These are reference figures: there is a lot of variation within each type. Overall, indoor venues with a published price (170) have a median of €184 for 15 children, against €255 for outdoor ones (52). So a roof doesn't have to mean a higher bill.
Indoor play centres and ludotecas (up to about 8 years old)
The safest bet in the rain: space to run around, ball pits, slides and, usually, a room for the snack. Browse indoor play centres. Ludotecas tend to be the cheapest option and have their own room, which suits small groups.
Trampoline parks (from about 6-7 years old)
Children burn a lot of energy in a short time, which is exactly what you need when a group is stuck inside. Check the trampoline parks and ask about age and height limits, and whether grip socks are included.
Bowling, escape rooms and games (from about 8-9 years old)
For older children, bowling or an escape room works very well: there is a shared goal and the weather is irrelevant. For escape rooms, check the maximum number of players per room; larger groups are usually split into teams.
Workshops and crafts (all ages, with adaptations)
Ceramics, cooking, science, painting: a workshop is a calm plan, and every child goes home with something they made. It suits smaller groups, or children who don't enjoy noisy places.
To see every covered option at once, open the birthday venues with a roof selection, or use the search and filter by indoor.
How to talk to the venue about postponing
If your party is outdoors (adventure park, farm, horses, paintball), the sensible thing is to ask about the rain policy when you book, not the day before. We don't assume how any given venue works, because it varies a lot, but these are the useful questions:
- What happens if it rains? Is there a covered area, or does the activity change?
- Can the date be changed at no cost? How late can we let you know?
- Who decides whether to call it off, the venue or the family?
- Is the deposit kept for another date or refunded?
- Are there free alternative dates the following weekend?
Ask for the answer in writing (an email or WhatsApp message is enough) and keep it. That avoids misunderstandings if the weather turns. Tell the invited families something like: "If it rains on Saturday, we'll decide on Friday at 6 pm and message the group."
A three-step plan B
- Pick two options from the start. One outdoor and one covered, ideally in the same area, so you don't have to change town at the last minute.
- Set a decision deadline. For example, 24 hours before. Checking the forecast every hour only adds stress.
- Announce any change early. One clear message with the address, time and parking saves a lot of phone calls.
When it rains, indoor venues fill up faster, so if the weekend looks bad, call early.
What to bring on the day
- Grip socks for every child (almost always compulsory at trampoline parks and play centres; ask whether the venue sells them).
- Comfortable clothes and a spare set, especially for the little ones.
- A bag for wet shoes and coats, and umbrellas or raincoats for arrival and departure.
- A list of the guests' allergies and intolerances, to hand to the host or the venue.
- Contact details for the families and photo permission, if you plan to share pictures.
- Water, wipes and a bin bag. They always come in handy.
- Cake and candles, if the venue lets you bring your own: check beforehand. If food isn't included, some places include the snack.
Frequently asked questions
Is an indoor venue more expensive?
Not necessarily. In our data, the indoor median (€184) is lower than the outdoor one (€255) for 15 children, although it depends on the activity. These are indicative prices, so confirm them with the venue.
How far ahead should I book a plan B?
Ideally, book the date for your main plan and ask at the same time what alternatives exist. Booking two venues at once rarely pays off, because most ask for a deposit.
Can I switch venue on the same day?
It's possible if the indoor venue has space, but it isn't reliable on a rainy weekend. Better to have it agreed in advance.
