From Santo Espiritu to Gilet, behind the Urbanization La Paz, you go along a rather bumpy trail, not recommended for beginners at all (I say this from experience, I met the ground with my bicep for the first time)
After La Mola, I should have turned left a bit before Pantanet to go via Pico del Aguila and Santo Espiritu, but I made a mistake and ended up almost in Rafelbuñol. I had to take the road through Liria to get back to Sagunto.
