I followed a northern route to reach 535 m and 539 m peaks near Las Casicas (Fortuna). In that route I pass by two others that I already know and El Cabezo del Sastre that I have left for the end.
About four hours on a hard terrain, with strong contrasts and ravines that force you to go up and down frequently.
In the end it was about 8 miles and four hours harder than I expected.
