Rough and narrow tracks cross steep ground but provide rapid ways between the north side of Alcazaba and Laguna de la Mosca at the foot of Mulhacens north face. This saves the long detour east round the eastern buttresses of Alcazaba and Mulhacen via Siete Lagunas.
The photo below is taken in winter but the snow outlines better the summer routes to follow from the Puntal de Goteron across the face.

The upper track across is called the Vasar de la Cuneta. The lower track is the Gran Vasar del Alcazaba.
The gully leading from the Vasar de la Cuneta to the summit of the mountain is called the Cuneta de Alcazaba. This is a steep and loose stone filled gully. Maybe makes a better ascent in winter when the slope is stabilised somewhat.
The ridge leading down to the right from the summit of Alcazaba is the Espolon de Alcazaba, a fine winter mountaineering route and also a high class scramble in summer (sections of V.diff rock 3+).
