The starting point is the square in front of the public swimming pools of Equi Terme, after that follow the signs crossing the Lucido river in the direction of the cemetery. After a short ascent on a tarmac road, take the CAI path 39 in the direction of Aiola (technically and physically demanding uphill stretch) until you reach the aforementioned village.
Leaving the large fountain on the left, cross the village until you encounter meadows, woodland and cultivated fields. Here you will start the first single track:

Aiola Trail – (Degree of difficulty: Blue on IMBA scale; Dist +839m / Dslv -105m)
At the end of the trail you will cross the Trekking Lunigiana which again runs alongside the Lucido river, and after having passed an ancient stone bridge, start to head for the village of Monzone. After crossing the village you will then start the paved ascent to Mezzana. Once here, enter the village and then cycle up between olive groves and bushes to reach Fazzano.
In the village of Fazzano we will find the homonymous single track, the second of the ring:

Fazzano Trail – (Degree of difficulty: Blue on IMBA scale; Dist + 1100 m / Dslv -220 m).
At the end of the trail, near the “Paradiso” fountain, leave the Pago trail behind and continue up a dirt road towards the village of Codiponte, and from there the tarmac road towards Casciana. Once you end up cycling in the hamlet of Bancola, turn left until you reach the village of Cascia. After the latter, proceed for about 2 km up to the starting point of the next trail:

Vertical Strap – (Degree of difficulty: Red on IMBA scale; Dist + 989 m / Dslv -249 m).
At the end of the track turn right to then cycle up a physically challenging ascent, following the
track of an ancient bridleway. After about 2 km you will find yourself back on the paved road between Mezzana and Casciana, towards which you will have to continue pedalling. After having left the village behind for approximately 1 km, in conjunction with a clearing on the right, you will find the last trail of the ring:

Gagliata – (Degree of difficulty: Red on IMBA scale; Dist + 1000m / Dslv -233m).
The trail ends when you find yourself in front of the Equi Terme railway and after having bypassed it on the local road, you end back to the starting point of the ring.
