Bosco dei Bordighi
Walk the flat path through Bosco dei Bordighi in early spring and the ground does something unexpected: it turns white. Wild garlic — Allium ursinum — spreads in dense, low carpets beneath the willows and alders, and the smell reaches you before the flowers do. This is a riparian nature reserve along the Adda River, just east of Sondrio, where white willow and black poplar shade a mosaic of forest, meadow, and cultivated field threaded by the Venina and Orsenigo streams.
The reserve documents 464 plant species and 107 vertebrate species across roughly 50 hectares. A marked botanical trail runs through it with plant-name plaques and ecosystem panels, making it a place you can actually learn something without effort.
💛 What travellers fall for
People who come back tend to time it around the seasons — wild garlic in early spring, the feathery unfurling of ostrich fern a few weeks later, woodpeckers audible year-round. The greater spotted woodpecker is the reserve's symbolic species, and it earns the title: you'll hear the drumming before you see it.
The story behind Bosco dei Bordighi
The reserve's origins trace back to 1987, when Comunità Montana Valtellina di Sondrio began pursuing the creation and formal management of the site. The process moved slowly, as these things do, and official establishment came through a regional council decree on 29 November 1994.
The Comunità Montana continues to manage it today, with director Cinzia Leusciatti overseeing operations. The goal from the start was conservation of the Adda floodplain habitat — a type of riparian woodland that has largely disappeared from the valley floor as agriculture and development have taken hold.
Good to know
The reserve sits between Albosaggia, Faedo, and Montagna in Valtellina, reachable on foot or by bicycle along the Sentiero Valtellina from Sondrio. No admission fee and no set opening hours. The trails are flat and well-marked — an hour or two is enough for a full loop.
Spring and early autumn are the most rewarding seasons: mild temperatures between 10 and 20°C, the forest at its most active, and the botanical trail at its most legible. Summer can be hot and humid in the valley, with June bringing the heaviest rainfall. Winter is cold and occasionally snowy, but the bare trees open up the river views considerably.

Nice
The Bosco dei Bordighi nature reserve is a park suitable for people of all ages, offering flat and not particularly strenuous trails. The trails are well marked. A bridge also leads to the Valtellina trail. Signs accurately illustrate the local flora and fauna. I recommend taking a walk in this reserve.
A beautiful nature reserve, a riparian forest located along the banks of the Adda River! The trail is marked with arrows, and there are information boards explaining the local flora and fauna. If you walk the trails in silence, you might be lucky enough to spot some of the forest's small inhabitants (I encountered squirrels and dormice). Watch out for nettles in summer, when the vegetation tends to overgrow the trails!
