This walkway is splendid, a piece of history of Bergamo mining activities. Along the route it is possible to find information panels with the history of the Opel Valley, about which information is scarce everywhere.

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
