Sagra del Balòch at the Colle di Zambla

In 2026 the festival fell on a Thursday and was the thirteenth edition. The Pro Loco's programme:

In 2024, at the eleventh edition, the festival ran from 2.30 to 6.30 pm, with over thirty stalls: mountain cheeses, cured meats, jams, cakes, honey and wines from the Bergamo area, and crafts in wood, textiles, stones and bread dough. The country games included a treasure hunt in the straw, skill games, a wheelbarrow obstacle course, target shooting with a laser rifle and the most talked-about game, the «Bingo mucca»: two hundred squares on the meadow, two cows, and you bet on where they will leave their mark.

There were also ponies, an educational farm from Gorno, a wood sculptor at work and, new that year, the Falconieri delle Orobie with owls, little owls, barn owls, buzzards and falcons, with the «glove baptism» at 4.30 pm. BergamoNews dated that edition «Sunday 13 August», but 13 August 2024 was a Tuesday: the festival follows the date, not the day of the week.

The Colle di Zambla, 1,264 metres, is the pass on the SP27 provincial road of the Val Serina, where the Val del Riso road from Ponte Nossa arrives: from the main village centre it is about 2.2 kilometres as the crow flies. On the pass there is a public car park that OpenStreetMap marks as free, and from Monday to Saturday Arriva's line B comes up, with its terminus at Passo Zambla.

The park at the Colle, as the Pro Loco programmes call it, also hosts other summer events: the stories and legends by moonlight at the end of June, with blankets spread on the grass, and posture exercises on Friday mornings.

From the Colle start the barrier-free walk to Pian della Palla and the Conca dell'Alben and the paths to Monte Alben and the Cima di Grem; in the woods next to the pass there is the Parco Avventura Monte Alben, which at the end of September 2026 was temporarily closed. In mid-August, for Zambla Alta, the ERA5 averages give minimums of about 11 °C and maximums of 20 °C. On the evening of 13 August 2026, at the Zorzone parish centre, there was the second evening of the hamlet's festival.
