Sea and nature centres run by the «Association pour la préservation des écosystèmes méditerranéens» (Association for the conservation of Mediterranean ecosystems). Organises two week long courses during the summer: children provide their own packed lunch and go from the sea centre to the nature centre and back again, helping the staff with their missions but always in a fun way. To help with these tasks they have: a library suitable for both younger and older children, a projection room, the beach, games etc... Important! They are only running one course in July and one in August, so you’d better not leave it too long to apply.
