Parque de Polvoranca, Nature park in Leganés, Community of Madrid, Spain

Parque de Polvoranca is a 150-hectare park in Leganés, south of Madrid, laid out around the Recomba stream and the Mari Pascuala and Sisones lagoons. It contains themed gardens, an arboretum, a botanical garden with over 400 species, a visitor centre and sports courts. The ruins of the 1655 San Pedro church stand within its grounds.

A medieval village once occupied this location before it was absorbed by Leganés in 1849. The only visible remains from that settlement are the ruins of San Pedro Church.

The Environmental Education Center offers workshops, exhibitions, and guided tours for schools and families focused on nature conservation and sustainable living. These programs help visitors understand the park's different habitats and how they function.

The park lies in Leganés beside the M-407, with the entrance signposted from the M-406. From Madrid, take bus 486 from Oporto metro station or bus 482 from Aluche; the C-5 Cercanías line stops at Parque Polvoranca station. From Fuenlabrada, the C-5 from La Serna station heads toward Bosquesur.

One of the lakes, Mari Pascuala Lake, is maintained at consistent water levels through a special waterproofing system that keeps it filled even during dry seasons. This engineering allows the park to preserve a functioning lake in an area with irregular rainfall.
