The road that draws an "S" on the dam is very scenic. All that remains is to tackle the last hairpin bends to the top and then enjoy the most beautiful view of the Alps and perhaps the world...

The climb of Colle del Nivolet is among the most exciting and fascinating of the Piedmont Alps, I always recommend Alba and Tramonti when the light transforms the landscape into pure magic!

Lake Agnel is part of a wonderful alpine environment, possibly the most beautiful and spectacular thing I have seen in the Alps. As soon as you leave behind Lake Serrú, an artificial dam, you reach this natural lake after a short descent. Leaving it behind in the direction of the Colle del Nivolet, the views from above are great. Beauty cannot be seen in photos nor described in words... you have to feel it arriving there by bicycle.

The ideal time for family hiking around Lake Serrù is generally during the summer months, from July to September. During this period, the trails are typically free of snow, and the weather is most favorable for enjoying the alpine scenery and wildlife. Outside of these months, conditions can be more challenging, with snow persisting into late spring and returning in autumn.
Access to Lake Serrù and the Colle del Nivolet area is primarily via the Strada Provinciale 50 (SP50). While specific public transport options directly to the highest points might be limited, shuttle services often operate during peak summer months to help manage traffic and provide access to trailheads. It's advisable to check local transport schedules before your visit.

Additionally, the nearby town of Ceresole Reale offers more options for cafes, restaurants, and hotels, serving as a good base for exploring the Lake Serrù area.
While many trails in the high alpine environment can be rugged, some sections, particularly the almost flat path directly alongside Lake Serrù, might be suitable for sturdy, all-terrain strollers. However, for most designated hiking trails, especially those with elevation changes or rocky terrain, a baby carrier is generally recommended over a stroller for comfort and safety.
