What is open at Dehesa Boyal in autumn and winter?
From September to May, Dehesa Boyal means two things: the woodland and the indoor pool. The tracks through about 230 hectares of holm oaks start at the sports centre, with no ticket and no opening hours. The indoor pools and the spa, which the centre, run by San Sebastián Deporte, calls a zona termolúdica, close only in August; winter hours and prices are given at the desk or on +34 916 59 29 23.
Lighting a fire is banned all year under the Comunidad de Madrid’s INFOMA fire plan, so there are no barbecue spots; picking mushrooms or fruit is also not allowed. For city alternatives in winter, see Madrid’s indoor pools in winter, and for longer walks, hiking near Madrid by train.
Do you count as a resident, and what does that save?
At municipal pools in Spain, the cheap rate is for people empadronados, registered on the town’s population register, the padrón. Living in La Moraleja or Alcobendas does not count: only registration in San Sebastián de los Reyes does. Everyone else pays the non-resident rate.
For two adults and two children aged 6 to 17, a non-resident family paid €43.20 at weekends and €28.80 on weekdays in 2026; a registered one, €23.00 and €16.00. Reduced tickets, for ages 6 to 17, pensioners and over-65s, were €5.40 and €8.10 for non-residents and €3.00 and €4.50 for residents. Under-5s go free, and registered large families (familia numerosa) pay the reduced rate for everyone. Tickets are bought at the desk; if you leave, you pay again to come back.
What are the summer pool rules that surprise visitors?
Spanish municipal pools have stricter rules than many visitors expect, and these are the ones at the Dehesa Boyal summer pool, which has several outdoor pools and grass lawns:
- No inflatables: no balls, fins or air mattresses in the water; armbands only.
- No loungers: chairs and sun loungers are not allowed on the lawns without medical authorisation. Bring a big towel.
- No picnics on the grass: food only at the bar and in the picnic areas.
- Children: under-12s must come with an adult, and one adult can bring up to four.
- Weather: no refunds if the weather turns.
