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.

The Marmitte dei Giganti of Valzurio, in the province of Bergamo, are spectacular natural basins carved out by the Ogna stream. These geological formations were created thanks to river erosion in areas once covered by glaciers. The hike to reach them is fascinating and also suitable for children, with a difference in altitude of about 300 meters and a travel time of 1 hour and 45 minutes - 2 hours. The most characteristic trail is the CAI 340, which follows the Ogna stream through the woods. A shorter alternative is the dirt road that starts from the car park in Spinelli. Along the way you will come across the Baite del Möschel and the suggestive Buco del Freddo, a stone construction used in the past to preserve fresh products. Once you arrive at the Marmitte, you can admire the crystalline water flowing between the rocks, creating a truly unique landscape

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.
