Biscia Bocco di Bargone e discesa su Castiglione

You can start from Chiavari, Lavagna or Sestri Levante simply moving flat along the Aurelia, you start by following the Ardesia bike path on the Lavagna side to avoid traffic, arrived at the blue bridge you join the road until you get to the Settembrin traffic circle following for Valgraveglia and Passo del Biscia, you have to be careful this part of the valley floor on weekdays because of the presence of quarry trucks, otherwise it is a road with little traffic and you pedal well.

Arriving in Piandifieno we leave the main road to climb toward Nascio and then Cassagna, where after a right turn where we follow for Statale a dirt road begins that takes us back on asphalt to Statale, where we take the uphill road that leads us to the Santa Rita water plant, from here we take the road that then becomes dirt that takes us to the Biscia Pass. At the pass we take the dirt road barred by the gate, which along the Alta Via delle 5 Terre will take us passing under Mount Porcile to the Bocco pass. Beware of the clearing below the Porcile where the single track up to the Bocco starts, we need to keep to the right and locate the trail.

After departing from the Bocco taking the dirt road that leads to Sestri Levante and Bargone, we leave it after 600 meters to follow a dirt road to the left towards the mines of Monte Zenone, at the hunters' stage we take the AV5T trail, if you have never gone there stay on the dirt road until its conclusion to see the mines, they are worthwhile, then turn back and take the trail again.

Once on trail, all rideable except for two ramps, you will come to a gorgeous forest, follow AV5T to the left, the trail has recently been cleared and is enjoyable.

Watch out for the fork to take on the right, still on AV5T towards Velva, here the trail becomes first dirt and then asphalt for 500 m. Do not follow for Velva or AV5T but stay on asphalt and after 300 m on the right a little hidden starts the path that will take you back to Castiglione Chiavarese. The last part follows old Genoese creuze, not easy to find the entrance. Once on asphalt you can safely descend to Sestri Levante and then return to the starting point.

Be careful of water supplies, especially in the summer months, the only two drinking fountains present are in Conscenti in the center next to the gas station and along the climb to Nascio.
