The excursionist or simply the enthusiast of "green walking" can choose among a diverse range of itineraries, all equally fascinating.
The superior area of the valley is under protection of a regional law from 1974 as "protected flowered area".
First of all, we can mention the long route from the Valley of San Pietro until the source of the Esino river (disl. 220m, 7 km, 3 h a/r), through a grip depression dug in the ridge between the Monte Costa (m. 914) on the righ and Monte Consegno (m. 998) on the left.
We can start by leaving the Porta Panicale, entering the road on the left, near the antique tannery and low colonial house, and continuing along the river, keeping to the south the Monte Cafaggio (m. 1116).
From here you can choose different green walking tours.
