Mirador de la Bunyola

Mirador de la Bunyola is a circular observation tower standing in the Delta del Llobregat natural area, on the edge of El Prat de Llobregat, right next to Barcelona. It's the kind of spot few visitors have heard of, yet it quietly rewards hikers, birdwatchers and plane spotters alike.

How do you get to Mirador de la Bunyola?

The tower sits inside the Delta del Llobregat natural spaces, reached via a marked trail starting in El Prat de Llobregat. The round trip on foot or by bike covers roughly 10 kilometres with only about 49 metres of elevation gain, making it an easy route that typically takes 2 to 2.5 hours to walk. Along the way you'll pass the ruins of the former Caserna dels Carabiners (a historic customs guard barracks) and El Semàfor, an old maritime signal post. Bring water and sun protection, since most of the path runs through open, largely shadeless terrain.

What can you see from the tower?

The viewing platform opens up a wide panorama: Barcelona and the Montserrat range on one side, the Garraf massif on the other, and straight ahead, the beaches of Ca l'Arana and Carabineros meeting the Mediterranean. In between lies a patchwork of the Baix Llobregat landscape — farmland, pine groves and wetlands that together form one of the most important wetland areas near Barcelona.

That mix of habitats — water, pine woods, fields and coastline — is exactly why the Mirador de la Bunyola draws birdwatchers. The Llobregat delta lies along a major migratory route, and the tower offers a convenient elevated vantage point without having to step into protected zones.

A completely different crowd shows up for another reason entirely: plane spotting. The tower's proximity to Barcelona-El Prat Airport means you get a clear view of aircraft taking off and landing, often with the sea and the delta as a backdrop. For many visitors, that combination is the main draw.

When is the best time to visit?

Early morning and late afternoon offer the softest light and the most comfortable temperatures — the site is fully exposed, and midday sun can make it uncomfortable, especially in summer. For birdwatching, spring and autumn migration periods bring the greatest variety of species through the delta. Plane spotters can visit year-round, since the flight schedule matters far more than the season.
