The L’Angla spring is located on the left or south side of the Calders river valley, between the Llac de Navarcles and Viladecavalls de Calders, near Navarcles but in the municipality of Calders and, consequently, in the Moianès region. The spring takes its name from the L’Angla farmhouse, documented since ancient times, through which the GR-3 trail passes. The spring is below the farmhouse, on a shady half-slope, facing a cliff of the winding Calders river and next to the L’Angla stream, in an oak grove with sections eroded by abusive logging and by excessive use of paths and foot traffic. The spring springs from above a rock. Around it, a small stone house was built, almost like a toy, large enough to sit in, with the back wall half made of natural rock where the water flows and half built of stone, two benches that follow the side walls and the water circulating on the ground and coming out of the door. The L’Angla spring is one of those that always flows. The L’Angla oak, with its beautiful shape and large proportions and therefore listed as a unique tree of Calders, stands out a few dozen meters below the spring. Text by Jordi Badia.

Mountain of saline and other waste created between 1945 and 1977. The La Botjosa salt dump measures 775 meters long by an average width of 150 meters, occupies 13.5 Ha and its content is estimated at around 4 million tons of salty waste. Since the start of the new Cogulló dump in 1977, the potash mining of Sallent and Balsareny stopped dumping saline waste in La Botjosa. Since then, a considerable portion of the saline residues dumped in the La Botjosa dump has disappeared by dissolution in rainwater and air humidity, as evidenced by the geomorphologies in lapiaz on the slopes and dame coiffée where an object acting as an umbrella has protected the salt below

The Parque de l’Agulla is a natural space located on the outskirts of Manresa, near the municipalities of Sant Fruitós de Bages and Santpedor. The park was born with the construction of the lake of l’Agulla between 1966 and 1974. The lake has a surface area of about 64,000 m2 and a capacity close to 200,000 m3. Its main source of water is the Sèquia de Manresa canal, of medieval origin.

Balsareny offers a diverse natural landscape. You can explore the riparian forests along the Llobregat River, which are rich in biodiversity and home to various bird species. The area also features unique geological formations known as 'dames coiffées' near the Séquia de Manresa, and forests predominantly composed of white pine, holm oaks, and small-leaved oaks.
Yes, several natural monuments are suitable for families. Parque de l'Agulla, a lake near Manresa, is a great option with a nice trail for walking and biking, parking, and a picnic area. Another family-friendly spot is Canyet del Muladar, which focuses on conserving endangered dryland fauna.
The region blends natural beauty with historical significance. The Resclosa dels Manresans, a medieval dam beneath Balsareny Castle, marks the beginning of the Séquia de Manresa, an impressive 14th-century irrigation canal. You can also visit the Dolmen, a historical site with trails, and the Font de l'Angla, a historic spring nestled in an oak grove.
Balsareny is known for its interesting geological features. Near the Séquia de Manresa dam, you can observe 'dames coiffées' (ladies with hats), which are unique rock formations created by differential erosion. Additionally, the La Botjosa salt dump, while man-made, exhibits natural geological processes like lapiaz and dame coiffée formations due to salt dissolution.
Yes, the area around Balsareny offers numerous trails for hiking and cycling. The Séquia de Manresa itself provides a unique natural trail for walking and cycling. For more structured routes, you can explore options for gravel biking, road cycling, and mountain biking that pass through the diverse landscapes of the region.
The best time to visit Balsareny's natural monuments is generally during spring (April-June) and autumn (September-October).

The Séquia de Manresa is remarkable for its blend of natural beauty and historical engineering. Built in the 14th century, this 26-kilometer medieval irrigation canal was a monumental feat for its time, supplying water to Manresa with a minimal elevation difference. Its path now serves as a natural trail, winding through forests, orchards, and fields, showcasing the rich natural environment and historical human ingenuity.
Parking availability varies by location. For instance, Parque de l'Agulla has dedicated parking facilities. For other natural areas like the Llobregat riverbanks or the Séquia de Manresa trails, it's advisable to look for designated parking areas in nearby towns or trailheads. Always check local signage for parking regulations.
The 'dames coiffées' (ladies with hats) are fascinating geological formations resulting from differential erosion. More resistant elements, such as sandstone slabs, protect the softer material beneath them, creating column-like structures topped with 'hats.' These formations are a natural testament to the powerful and artistic forces of erosion over time.
