Approach
Follow the path from Secteur 9 until you come to a steep gulley cominhg from above. Scramble up and the cliffs on the right (east) are Secteur 7.
The routes here have a great advantage of having a westerly orientation and shady belay positions - as opposed to sectors 9 & 8 that are very exposed to the South and heat up quite impressively in direct sunlight.
Ethic
Park where indicated, take care of the environment, buy the local guidebook when possible (this is one of the ways you can help local route setters), clean up your shoes before climbing, don't spray beta, be polite.
