The Sambuco ring, from Fabbriche

Introduction

Sambuco is indeed a beautiful village, probably unknown to most people, but still, incredibly, in the municipality of... Genoa... I had already visited the hamlet years ago and remembered tractors, cows and a chicken coop, and I partly relived that memory. The whole area is still very well preserved, with many dry stone walls in perfect order...

Description

The path is not marked at the beginning, but there are a couple of signs that help.
The first one, church square, gives the Gava pass, which is only an hour away, but this is a bit too optimistic (more reasonable perhaps 75-90 minutes). The second signpost is 5 minutes after the last building of 'Case Stellin'.
Parodi's book is also very useful (but not the one referring to Beigua, but rather the one on the mountains of Genoa - excursion No. 3), which gives clear indications.
You pass two not easy fords and then climb a very short passage that requires a minimum of attention; in the central part you can glimpse the old orange stripes that have been partly erased and replaced with red and white flags, which have now faded (perhaps a less resistant paint has been used, because it is worse preserved than the previous marking system); again, when you are about to reach the Gava pass, there are no more signs.
This makes the route perhaps unsuitable for those who do not have at least a minimum knowledge of the area. In addition, it is better to avoid periods when the weather is too hot, both because of the temperatures and because the presence of a lot of tall grass makes it more difficult to 'see' the path.
So you arrive at the Gava pass (752 m), an important crossroads of paths, and you climb up the two red roundabouts.
On the way up I caught a glimpse of a couple of stones that still bear the signs of the sledges that used to transport the timber down into the valley. Then we turn left for the Gilwell shelter (890m) on a branch road, leaving the FIE sign behind. The building was open and used by a group of young people (a little higher up is the Bullu spring). After the lunch break we returned to the main path and climbed up with the two red roundabouts to the crossroads (at an altitude of around 1000m) with the empty red square (just redrawn), then following the latter downhill back to the hamlet.

COMMENT (bearing in mind that the tour was done in 2008 and then repeated in 2016)
Along the way, several times, we saw the ruin of "casa Ravazze o Tilla", splendid in this sense the volume of the Argentea mountain community (you can download the pdf of the book from the website) that tells all the stories of the structures in the area... Another beautiful point glimpsed, a bit from afar, is the jump of the rio Malanotte (about ten metres?). Who knows, maybe between the two fords there is a chance to get to the base of the jump, but I realised the little waterfall when I was a little too far from the point and it was already late to go back and look...
