Moregallo, Mountain summit and viewpoint in Valmadrera, Italy.

Moregallo is a 1276 m mountain at the eastern tip of the Triangolo Lariano, on the border between Valmadrera to the south and Mandello del Lario to the north. Three crests descend from its grassy summit: the short south-west one toward the Corni di Canzo, and the east and north crests dropping into the lake of Lecco. The south face above Valmadrera is cut by vertical rock bands forming spurs, while the east face falls to the water in gullies and high walls.

The first documented route to the summit appears in Silvio Saglio's 1957 guide for the Touring Club Italiano and CAI Milano, which listed only the crest itinerary from Bocchetta delle Moregge. The path to the chapel of San Isidoro on Sasso di Preguda was already known in the time of abbot Antonio Stoppani. Between the 1980s and 1990s, Valmadrera sports associations traced the south-side hiking and climbing routes.

The chapel of San Isidoro stands on the Sasso di Preguda, a granite erratic block on the eastern crest carried there from the Val Masino; the abbot Antonio Stoppani already knew the path to it. The Sasso is also the trailhead for the Cresta Est route to the summit, and the spring of Sambrosera on the south side is named after the Bocchetta di Sambrosera above it.

The southern routes are rated EE (experienced hikers): steep, exposed sections need hands or a firm step, and short chains appear on the Canalone Belasa and Cresta Ovest. Only two water points exist, the Sambrosera spring at 750 m and the Fontana Sezione Femminile OSA at about 1150 m, the latter not always flowing. The tunnels between Parè and Rapanui/Moregallo are closed to walkers, so a loop back down the south side needs two vehicles.

The Sambrosera spring sits at 750 m on the south side, not 715 m, and is one of only two water points on the mountain; the other, the Fontana Sezione Femminile OSA at about 1,150 m on the east side, does not always flow. The Sasso di Preguda, a granite erratic carried from the Masino valley, lies on a ledge of the east ridge.
