Micropolix is a covered play city for children aged 4 to 14, where they put out fires, drive on a road circuit and pay with Eurix, the city’s own money. It sits in the Parque Alegra retail area of San Sebastián de los Reyes, north of Madrid, with more than 30 activities over 12,000 square metres, and the venue suggests 3 to 5 hours for a visit. It opens to the public only on Friday evenings and at weekends, and adults pay too: from €10 on a Friday to €15 on a Saturday.
Micropolix is an indoor children’s leisure centre in San Sebastián de los Reyes built as a miniature city for ages 4 to 14.
Is Micropolix worth it? Micropolix is worth it for children aged 7 to 14, who can do almost everything, and on a rainy day, since it is fully indoors. A child pays €14 on a Friday and €20 on a Saturday at the gate, and each adult €10 or €15. Activities run in Spanish; English visits exist only for schools.
Will my child enjoy it without Spanish?
Micropolix runs its activities in Spanish, and according to Micropolix the English-language visits are for school groups only. Hands-on activities such as the firefighters or the road circuit work with little language, but the role play and instructions do not, so it suits bilingual families or children with some Spanish best.
What can each age do?
| Age | What they can do | Gate price, Friday |
|---|---|---|
| 7 to 14 | Every activity except Microcircuito and soft play | €14 |
| 4 to 6 | Most activities, not the adventure ones such as firefighters; road circuit from 1.15 m (3ft 9in) | €13 |
| Under 4 | Soft play room only | Free |
| Adults | Accompany; the venue advises staying with under-7s | €10 |
Activities cannot be booked and run first come, first served, in turns of 15 to 20 minutes.
How does a visit fit Spanish meal times?
Spanish families eat lunch around 2pm and a late dinner from about 9pm, and Micropolix opening hours are built around that. Two house rules turn this into a planning question: no outside food, only water up to 500 ml, and children cannot leave and come back in. So a weekend visit means lunch in the on-site cafeteria or restaurant, which has allergy options.
- Friday evening suits a family on holiday that has done sightseeing all day: go straight from the Metro, have a snack inside and eat a late dinner afterwards, as Madrid does.
- Saturday or a special day means lunch inside Micropolix, since outside food is not allowed.
- Sunday closes at 5pm, so allow for a late lunch inside or a snack and an early dinner after.
Which day is cheapest?
A family of two adults and two children aged 7 to 14 pays €48 at the gate on a Friday, €52 on a Sunday and €70 on a Saturday; online it is €46, €51.80 and €69.80. Friday and Sunday are also the quieter days, per Micropolix.
| Day | Family of four, online | Hours |
|---|---|---|
| Saturday | €69.80 | 11.45am to 8.30pm |
| Special days | Saturday prices | 11.45am to 6pm |
| Sunday | €51.80 | 11.45am to 5pm |
| Friday | €46 | 5.45pm to 9.15pm |
Booking online saves only a few cents a head, but it secures entry on a busy day; the activities inside cannot be booked. In autumn 2026 the special days are 10-11 October and 31 October-1 November. December dates were not yet on sale at the end of September, and Micropolix closes for all of August.
How do I get there from central Madrid?
Micropolix is in San Sebastián de los Reyes, a town north of Madrid, not in the city itself, so plan it as a half-day out.
- Metro: Line 10 runs to Hospital Infanta Sofía, about 1 km on foot from Micropolix. Until the end of 2026 the line is cut between Nuevos Ministerios and Cuzco, so from the centre you join it north of Cuzco, at Plaza de Castilla for example.
- Which ticket: the stretch from La Granja is MetroNorte, zone B1, so the basic Metro single does not cover the trip from the centre. The single ticket that does is the €3 combined ticket, according to the CRTM; fares are in Madrid Metro ticket prices.
- Bus: 152C from Plaza de Castilla stops by The Style Outlets, opposite Micropolix, and saves the walk with small children.
For lunch or dinner in town with children, see eating out with kids in Madrid. If the weather is the reason you are looking, what to do in Madrid on a rainy day has other indoor options. For other paid days out, see Madrid amusement park tickets, Madrid Zoo or Faunia and the Madrid Planetarium, and for free ones, free things to do with kids.
Micropolix questions from visiting families
Is Micropolix in English?
No. Micropolix runs its activities in Spanish and offers English-language visits only to school groups. Children who do not speak Spanish can still join the hands-on activities, but the instructions and role play are in Spanish, which suits bilingual families best.
What age is Micropolix for?
Micropolix is for children aged 4 to 14. Ages 7 to 14 can do every activity except the Microcircuito and the soft play room. Ages 4 to 6 miss the adventure activities, such as the firefighters, and need to be 1.15 m, about 3ft 9in, for the road circuit. Under-4s go free but only use the soft play room.
How much are Micropolix tickets?
At the gate, a child aged 7 to 14 pays €14 on Friday, €20 on Saturday and €16 on Sunday, and adults pay €10, €15 and €10. Online prices are a few cents lower. A family of two adults and two children pays €46 online on a Friday and €69.80 on a Saturday.
How do I get to Micropolix from Madrid by public transport?
Take Metro Line 10 to Hospital Infanta Sofía and walk about 1 km, or take bus 152C from Plaza de Castilla, which stops by The Style Outlets opposite Micropolix. Until the end of 2026 Line 10 is cut between Nuevos Ministerios and Cuzco.
Which Metro ticket do I need for Micropolix?
The last stretch of Line 10, from La Granja to Hospital Infanta Sofía, is MetroNorte in zone B1, so from central Madrid the single that covers the trip is the €3 combined ticket, according to the CRTM. The basic Metro single does not reach it.
