Parc de la Llacuna

Parc de la Llacuna is a pocket of green space in Montcada i Reixac, a town on the northern edge of Barcelona, set within the industrial belt of the Vallès area. Locals often describe it as the "green lung" of the municipality — a quiet counterpoint to the factories and transport corridors that surround it, and an easy nature break for both residents and visitors.

What will you see there?

The park's centerpiece is a small lake covering less than half a hectare. Its origin is unusual: the basin formed where sand and gravel had once been extracted, and once quarrying stopped, water gradually filled the depression left behind. Over time the pond naturalized on its own, without deliberate landscaping, and today it supports a habitat of real ecological value, drawing waterbirds and other species tied to wetland environments.

Around the lake, viewpoints and observation platforms have been installed, each fitted with information panels. These explain how the natural ecosystem works and which plants and animals live around the water, giving a short walk through the park an educational dimension as well — a detail that works particularly well for families.

The surrounding land has been planted with roughly 2,000 trees along with a mix of other vegetation, which has visibly softened the microclimate and the look of the area over recent years. Nature trails wind through the whole site, letting visitors move at an unhurried pace from one information point to the next.

Families will find a children's play area, while more active visitors can use the dedicated sports zone. Picnic tables are scattered at several points, making the park a natural stop during a longer walk or cycling trip through the area. In the section known as Mas Duran, a dog park of roughly 2,000 square meters has also been set up, complete with a water fountain for pets, so dogs can run off-leash without disturbing other park users.

How do you get there?

Montcada i Reixac sits right next to Barcelona, so the trip from the city center usually takes somewhere around fifteen to twenty-five minutes by car or by the regional transport links connecting the Vallès area with the metropolitan area. The park itself lies within the Can Duran / Mas Duran area of the municipality, which is worth entering directly into navigation apps when planning the route. It also functions as a starting point or waypoint for local walking routes that connect it to other parts of town, making it a convenient stop during a longer visit to the area.

When should you visit?

Spring and autumn are the best seasons to visit, when the vegetation is at its fullest and temperatures are comfortable for a longer walk around the lake. Summers in the region tend to run hot, so it's worth planning a visit for the morning or early evening hours. Thanks to the information panels and marked trails, the park works well at any time of year — it's a low-key, peaceful spot that doesn't require much planning ahead.
