The Recommended Route is exactly as per the Tuscany North book. It is a 4.5 mile clockwise loop via Monte Alto, with a 1.5 mile "tail" used for both the walk-in and the walk-out.
It ascends the rocky south east ridge of Monte Alto, offering a number of short scrambles and 2 small optional Via Ferratas. The descent is via the less rocky and slightly longer east face route.
From Ristorante Giannarelli at Passo Cerreto, Monte Alto can be seen clearly . From the back of the ristorante take path 00 which undulates north-westwards through peacefully wooded countryside . Monte Alto can be seen more closely from a break in the trees where the path crosses a dirt road.
After passing through more woods the path begins to climb the lower slopes of Mone Alto . The views back across the valley to the hills on the other side are wonderful . At a major path junction keep to path 00 to climb much more steeply to eventually gain the southeast ridge of the mountain via a small scramble over a defending rocky outcrop .
A few hundred metres further along the ridge a grassy ledge beneath some rocks provides an ideal lunch location . From here the remaining half mile of the ridge can be seen ascending in a series of rocky steps .
Although the ridge is fairly exposed and narrow , the slope on each side is not life threatening . This means that those with the appropriate level of confidence can simply walk along it . However, some may prefer to crawl! The final 100m of ascent is significantly steeper but not difficult and the views from the summit signpost are stunning.
Turn right on the summit to descend on path 671, initially walking to the north-east. An optional visit to a nearby secondary summit requires ascent and descent using two short Via Ferratas. However, these are easily by-passed by the main path which runs just below its left flank.
Path 671 runs north east for a further 0.5 miles descending gradually over rocky ground before turning southeast, for a further 1.5 miles of gradual descent down to the valley floor . It then heads east-south-east along the valley floor to the valley mouth, where there are views back to the start point, still 2 miles distant.
Here path 671 turns southwards for half a mile until it meets path 00 again, in the clearing crossed by the dirt road mentioned in the first paragraph. From here simply reverse the "tail" part of the ascent, south-eastwards on path 00.
