The Sanguigno Valley is one of the wildest and most fascinating valleys in the Bergamo Orobie mountains, located above Valgoglio (BG). Known as the "valley of water" for its abundance of waterfalls, pools, and peat bogs, it is considered the oasis with the highest biodiversity in the Orobie Park. 🌿 Main features Unique biodiversity: the valley is home to rare habitats such as extensive peat bogs, rhododendrons, pine forests, and endemic plant species. Origin of the name: "Sanguigno" comes from the reddish hues the vegetation takes on in autumn, making the landscape particularly evocative. Water is the protagonist: the Sanguigno stream cascades down, forming waterfalls and natural pools of green and blue hues. Wild environment: shady forests, bright meadows, crystal-clear lakes, and panoramic ridges create a varied and pristine landscape. 🚶♂️ Excursions Access: Start from Valgoglio (929 m), reaching the Aviasco power plant (965 m) where you can leave your car (ticket required). Classic route: The trail runs alongside the stream and leads to the Gianpace Refuge (1330 m), a refreshment point and waterfall observation point. Duration: Approximately 1.5–2 hours of walking, with moderate elevation gain. Alternatives: From Novazza, you can follow trail 232A, which passes through woods and pastures to the refuge. ✨ Why visit it Unspoiled nature: The valley is largely untouched, ideal for those seeking silence and authenticity. Photography and relaxation: The waterfalls and meadows offer spectacular views and picnic spots. Seasons: In spring, it is lush and green, in autumn it turns red and orange, and in summer, it remains cool thanks to the stream.

Wonderful area nestled between the rocky peaks of the surrounding peaks, in particular the Arera and the Corna Piana. The area is mainly rocky, easy to reach even if it requires a minimum of training. The most fascinating aspect is the landscape, you find yourself in a very natural and at times wild environment, where you also have to pay attention to small ravines which are often not immediately visible but equally dangerous! Especially in the presence of snow which masks them further.

Beautiful 2 hour walk, the first part, walking on a very wide, shaded road, talking alongside friends

The entire first part, lasting approximately 1 hour, is a gentle climb, for a walk with friends, exchanging a chat, on a very wide, shaded path that runs alongside the stream. The second part begins to climb, becoming a narrow and quite steep path, but to be done without any problem. The third part is a classic steep and narrow path, to reach the bivouac at the top, which however I did not do

Val de Gru is the terminal waterfall of the Val Vertova puddle path. It is the largest waterfall on the Val Vertova pool trail, which forms thanks to one of the lateral tributaries of the Val de Gru. From here the path continues up to the Testa bivouac.

The region around Premolo offers several significant gorge-like features. The Sanguigno Valley is known as the "valley of water" with abundant waterfalls and pools, showcasing high biodiversity. The Arera Basin is a natural monument nestled between rocky peaks, offering a wild environment. Additionally, the Val Dossana (or Nossana Valley) is a wild and beautiful valley with sheer cliffs and geological significance, featuring the source of the Nossa stream.
Yes, you can find excellent hiking opportunities. The Val Dossana offers trails like Sentiero 242, which traverses through the "pools of the canyon of Val Dossana," allowing you to experience deeply incised valleys and natural water features. The Sanguigno Valley also provides trails alongside its stream, leading to waterfalls and natural pools.
The canyons and gorges around Premolo are rich in natural beauty. You'll encounter stunning waterfalls, such as the Val de Gru Waterfall and the Val Vertova Waterfalls, often accompanied by clear pools and streams. The landscape also features ancient beech forests, traditional alpine huts, and rugged rocky terrain, especially around the Arera Basin.
Yes, the wider Val Seriana area, accessible from Premolo, offers guided canyoning and aquatic trekking experiences. Spots like Fiumenero are popular for navigating streams and gorges, with opportunities for jumping into crystal-clear pools, sliding down natural toboggans, and rappelling down waterfalls. These activities are generally accessible and provide an adventurous way to explore nature.
The best time to visit depends on your activity. For hiking and general exploration, spring and autumn offer pleasant temperatures and beautiful scenery, with autumn bringing reddish hues to areas like the Sanguigno Valley. Summer is ideal for water-based activities like canyoning and aquatic trekking, as the streams and pools provide a refreshing experience. However, summer weekends can be very busy, especially around popular spots like the Val Vertova Waterfalls.
Many areas offer family-friendly options. The cycle-pedestrian path alongside the stream leading to the Val Vertova Waterfalls is a beautiful and generally easy walk, though some sections can be steep. For canyoning, many guided experiences in Val Seriana are designed to be accessible for beginners and do not require high athletic or technical skills, making them suitable for families comfortable in water.
The Val Dossana is considered a "real living geological tract." It provides evidence of a vast ancient tropical sea and volcanic activity that contributed to the formation of the Orobic mountains over millions of years. Exploring this valley offers a unique insight into the natural phenomena that shaped the region's landscape.
Beyond exploring the canyons, the area around Premolo offers a variety of outdoor activities. You can find numerous mountain hikes, running trails, and cycling routes. These range from moderate to difficult, allowing you to explore the diverse landscapes of the Val Seriana, including forests, alpine pastures, and panoramic ridges.
While popular spots are well-loved, the Val de Gru (the gorge, distinct from the waterfall) is described as a "little known corner of the Seriana Valley." It can be reached from Orezzo or Cazzaniga and offers interesting glimpses as it transitions from a narrow gorge to more open areas, ideal for those seeking a quieter experience.
The Val Dossana holds significant historical context, with archaeological finds discovered in the "Canal D'Andruna," a ravine within the valley. These discoveries include human remains and flint tools dating back to 3000 BC, indicating a long history of human presence and activity in this rugged natural environment.
For guided canyoning trips in Val Seriana, technical equipment such as wetsuits, helmets, and harnesses are typically provided by the tour operators. However, it's advisable to bring swimwear to wear under the wetsuit, sturdy shoes that can get wet (or water shoes), a towel, and a change of clothes. Always confirm specific packing requirements with your chosen guide or outfitter.
Many of the gorges offer spectacular viewpoints. The Arera Basin is particularly noted for its wonderful area nestled between rocky peaks, offering a wild and natural landscape. The Sanguigno Valley also provides numerous spots with waterfalls and meadows that are perfect for photography and relaxation.
