Plaza Esperanto, Castelldefels a Avinguda de la Constitució, Castelldefels

Start at the town square and head west on the main road for roughly a hundred metres. The road becomes a gravel path, mostly flat for a small portion, with a few gentle inclines. Continue on the gravel path for around ten kilometres, passing through rolling countryside. The path narrows a little towards the end, but mostly stays open.

Eventually, the path turns into a road and you pass a few farms on your right. The road is mostly flat, with a small incline just before you reach the end of the route.
