Castello did San Nicola de Thoro- Plano above Maori

My husband and I are going to hike the Path of th Gods tomorrow from Bomerano to Nocelle and then walking down to Positano. Our time in Positano is running short and we would like to see this castle. Is there a way to take a detour off the Path of the gods above Maori to visit the CCastello? Grazie!
