This itinerary goes through the natural area, in its central section, taking in a number of major points of interest.

The access
The starting point is the large car park that lies just past the S. Brigida sign (400 m), which is also served by SITA coaches.
Retrace a few hundred meters towards Florence (west) and walk up via delle Lucole, named after the imposing fortified-house dominating the road. From here a flat dirt road, sided by drystone walls takes you to the edge of farmland.
 

The ancient road
The “official” access to the woodland is through a gate created in the 18th century by the Leonardi family, the local landlords. From here, a beautiful cobbled road, properly restored, takes directly to the Sanctuary. This is the old pilgrimage road, tramped for centuries, and fixed this way at the beginning of the 19th century.
The scenery is suggestive: the old cobbled road, the drystone walls, the stream, the tall trees siding the way and the artefacts witnessing the religious atmosphere of these places.
From the starting point, it takes about an hour to reach the Sanctuary of the Sasso (566 m), and the walk might well finish here if you tie it in with a visit to the religious building. The return walk takes less than an hour.

A variety of vegetation
For those loving longer walks, do not linger visiting the Sanctuary and instead take path nr. 2, going up from behind the “Casa del Pellegrino”.
The path makes its way through a very interesting Mediterranean environment, among oaks and heather, home to wild boars and roe deer.
The crossing of the stream implies the switch from the warmer to the colder side of the mountain, from oak to chestnut trees. After getting to the ridge, follow the path CAI 00 along it for about 500 m and take the path CAI 5 going off left (838 m).

The Cistus laurifolius
The descent on path CAI 5 goes through chestnut woods, now mainly coppice, to finally meet a particular area of tall bushes which, during the warmer months, bear leaves similar to those of the more known laurel: you’re in a protected area, created to safeguard this botanic rarity (cistus laurifolius).
These bushes blossom in May and the flowers do not last very long.
The path steeply descents towards the village, reaches a road to finally get to Lucole, after passing through some terraced fields.
