how is the road to the beach in chapter 7 symbolic in this chapter?

The road to the beach is one of freedom. Edna is free from the responsibilities of the children, and as a wife. This is symbolic of her desire to break free from her family.... a part of the awakening.

The two women went away one morning to the beach together, arm in arm, under the huge white sunshade. Edna had prevailed upon Madame Ratignolle to leave the children behind, though she could not induce her to relinquish a diminutive roll of needlework, which Adele begged to be allowed to slip into the depths of her pocket. In some unaccountable way they had escaped from Robert.

The walk to the beach was no inconsiderable one, consisting as it did of a long, sandy path, upon which a sporadic and tangled growth that bordered it on either side made frequent and unexpected inroads. There were acres of yellow camomile reaching out on either hand. Further away still, vegetable gardens abounded, with frequent small plantations of orange or lemon trees intervening. The dark green clusters glistened from afar in the sun.
