In reply to JimboWizbo:
Some of the Font boulders at Dame Jouanne are quite high, particularly La Dame Jouanne itself which is a big pinnacle about 8m high. I certainly wouldn't feel comfortable soloing it - the photo in the French guide book "Escalades et Randonnees by Arthaud shows climbers climbing it roped.
The nearest sport is at La Muraillette de Glandells, near Glandelles where there are about 2 dozen routes to the south of Nemours. The guide book recommends 15m/20m and 3 or 4 quick draws.
