Trail 591C links the Colla di Gritta, on trail 591 between Soviore and the Mesco, with the Crocettola on the Alta Via delle Cinque Terre: about a kilometre, rated by the National Park for experienced hikers and also rideable by bike.
It starts about a hundred metres past the Colla di Gritta, along the 591 towards Soviore and Il Termine. The first metres are almost vertical, then the path levels out and winds without a break through a mixed wood of pine, holm oak, strawberry tree and chestnut, with views over the Levanto valley and its hamlets.
It reaches the ridge at the Crocettola, where it crosses the Alta Via. Walked the other way, from the Crocettola, it lets you reach the 591 without the long tarmac stretch of provincial road 38.
