Nestled along the slopes of the Collserola mountain range, the Carretera de les Aigües is one of Barcelona’s most stunning and tranquil walking paths. Known for its breathtaking panoramic views of the city and its easy, flat terrain, this historic trail offers locals and visitors a peaceful escape from the bustle of urban life. Whether you’re exploring on your own or as part of a private tour, the Carretera de les Aigües is a perfect way to discover the natural side of Barcelona.
Despite its name—which translates to “Water Road”—there’s no water flowing here today. Originally built as a maintenance path for water pipes that served the city, the route has since been transformed into a beloved recreational trail for walking, jogging, and cycling. It runs approximately 10 kilometers along the mountainside, offering gentle terrain ideal for all fitness levels.
A Balcony Over Barcelona
What makes the Carretera de les Aigües truly remarkable is its view. Often called the “balcony of Barcelona,” the trail offers unobstructed vistas across the city. From this elevated position, you can spot famous landmarks like the Sagrada Família, Torre Glòries, and the Mediterranean coastline stretching out to the horizon. It’s a photographer’s dream and a peaceful retreat for those wanting to see the city from a new angle.
Many private tours in Barcelona now include a visit to this scenic path, especially those focused on nature, wellness, or off-the-beaten-path experiences. It’s an excellent way to blend physical activity with sightseeing while avoiding the crowds typical of more central tourist spots.
Nature Meets Urban Life
The trail is part of the larger Collserola Natural Park, one of the largest metropolitan parks in Europe. Rich with Mediterranean vegetation—pines, rosemary, and holm oaks—the area is also home to wildlife such as birds of prey, rabbits, and even wild boars. The contrast between lush greenery and the sprawling city below makes every visit feel like a mini escape into the wild, without ever leaving Barcelona.
Whether you’re a seasoned hiker or a casual stroller, the Carretera de les Aigües offers something for everyone. Its mostly flat terrain makes it accessible for families with children, seniors, and even those on bicycles.
Easy Access Points
Reaching the trail is easy. One of the most popular entry points is via the Funicular de Vallvidrera, which connects with the FGC train at Peu del Funicular. After a short ride and a quick walk, you’re right at the trailhead. Other access points are located near Sarrià, Esplugues de Llobregat, and Sant Just Desvern, making the route flexible for both short walks and longer excursions.

A Local Secret Worth Sharing
While Barcelona is famed for attractions like Park Güell, the Gothic Quarter, and La Rambla, the Carretera de les Aigües remains a relatively hidden gem. For locals, it’s a cherished place to unwind. For visitors, it offers a rare opportunity to see the city from a different, quieter perspective.
Whether you’re walking hand-in-hand on a romantic evening stroll, capturing photos of Barcelona at golden hour, or enjoying the area as part of a private tour, the Carretera de les Aigües will leave a lasting impression. It’s a reminder that sometimes, the best way to see a city is from just outside it—looking down on its beauty in peace.
