Why go

Sasso di Preguda is a glacial erratic of ghiandone granite on the slopes of Moregallo, at 647 metres above sea level in Valmadrera.

About seven metres high, it was carried more than eighty kilometres by glaciers from Val Masino. It has been a regional natural monument since 1984; a plaque recalls the work of geologist Antonio Stoppani. The church of Sant'Isidoro stands against its southern face, built between 1895 and 1899 after a livestock epidemic. The rock forms the church's rear wall and apse. The plateau overlooks the Lecco branch, the Brianza lakes, Resegone and San Martino.

A boulder brought from the Val Masino by the glaciers, and the little church built against its face.
A short climb through the woods, to a view over the lake, the Brianza lakes and the Resegone.
