The ramparts are a great spot for photography - the waves crashing against the wall, birds flying, the colours of the fishing boats in the distance, rocks. Go early evening or sunset for best dramatic light.
Careful were you step - the surface can be very uneven.
There are little shop set in the inner wall of the ramparts - mostly gift and craft shops. Prices are surprisingly a lot higher than in Marrakesh - especially for the metal lamps / iron works.
