Fiumelatte Waterfall & Village
Just a 25-minute walk south of Varenna along the lakeshore path lies the tiny hamlet of Fiumelatte, home to a geological curiosity that fascinated Leonardo da Vinci: a torrent that gushes white as milk (hence the name) from a cave in the cliff face for only eight months of the year, then vanishes completely. It is one of the strangest and most delightful micro-excursions on the lake.
The River That Disappears
The Fiumelatte is officially Italy's shortest named river at just 250 metres long, plunging from its cliff-cave source directly into Lake Como in a frothy cascade that is genuinely spectacular in spring snowmelt.
Leonardo noted the river's mysterious seasonal behaviour in his notebooks around 1490, puzzled by where the water went each autumn — a question that wasn't fully answered until modern speleologists explored the cave system above.
The Walk There and Back
The lakeside path from Varenna to Fiumelatte passes old boathouses, lemon-terraced gardens, and a small beach at Pino; it is flat, scenic, and takes about 25 minutes at an easy pace.
From the hamlet, a steep signed trail climbs through woodland to the cave mouth above the waterfall — allow 30 extra minutes for the round trip, and wear shoes with grip as the path is rocky near the top.
