Gleno Dam Trail (CAI 410)

The trail, marked as CAI 410, begins its ascent from Bueggio (1,052 meters above sea level). You can typically find parking in or near the village of Bueggio, which serves as the trailhead for this route.

The initial section of the trail is gently sloping alongside the Povo stream. After the 'Ponte del Gleno' area, it becomes steeper and enters a dense forest. You will navigate sections with roots and rocks, and the slope can be demanding. Midway, parts of the trail are carved into the rock face, offering views that overhang the valley. Closer to the dam, the path levels out before a final small ascent to a ridge.

No, this trail is considered difficult and requires a good level of fitness. It involves a significant elevation gain and challenging sections with roots and rocks. Less experienced hikers might find other routes to the Gleno Dam, such as CAI 411 from Pianezza, more manageable.

The route offers a blend of natural landscapes and historical elements. You'll hike through dense forests, observe 'giants' kettles' (unusual rock cavities), and enjoy panoramic views of the Presolana mountain range. Notable highlights include the Corna Wildlife Observation Tower and the Sgüsade Wildlife Observatory. The main attraction is, of course, the stark and haunting Gleno Dam ruins themselves, with the green lake that has formed behind them.

The trail is best enjoyed during the warmer months, typically from late spring to early autumn, when the weather is stable and the paths are clear of snow and ice. Much of the trail benefits from forest shade, making it pleasant even on sunny days. Winter conditions can make the trail significantly more challenging and potentially hazardous due to snow and ice.

While the trail is generally accessible for dogs, given its difficult rating and challenging terrain with steep sections, roots, and rocks, it is best suited for fit and experienced dogs. Always keep your dog on a leash, especially near wildlife observation areas and around other hikers.

No, there are typically no specific permits or entrance fees required to hike this trail or to access the Parco delle Orobie Bergamasche. However, always check local regulations before your visit, especially for any updated rules regarding protected areas.

While the trail itself is quite remote, you will find the Gleno Lake Kiosk near the dam, which can offer refreshments. It's always advisable to carry sufficient water and snacks, as facilities are limited once you start the ascent from Bueggio.

The Gleno Dam, built between 1916 and 1923, was an ambitious hydroelectric project. However, due to poor construction, a central section of the dam collapsed on December 1, 1923, just 40 days after its reservoir was first filled. This catastrophic event caused widespread destruction in the Scalve Valley and resulted in the loss of 356 lives. The wide gash in the 160-foot-high concrete barrage remains a visible and haunting reminder of the tragedy, offering a journey 'in the footsteps of history'.

Given the trail's difficulty and length, it's essential to bring appropriate gear. This includes sturdy hiking boots, sufficient water, snacks, a first-aid kit, sun protection, and layers of clothing suitable for changing mountain weather. A map or GPS device is also recommended, along with a fully charged phone. Trekking poles can be very helpful on the steeper sections.
