Archelon offers volunteering opportunities on the islands of Zakynthos, Crete and Peloponnesus that are the main nesting areas for this species (Caretta caretta) in the Mediterranian. For more than twenty years this organisation has been conducting surveys on the mentioned islands. In Athens, the organisation has a rescue centre for the sea turtle rehabilitation.

On the islands the work is seasonal (from may to october) corresponding to the nesting season, while in Athens the work is all year round.

The work on the islands in based around three main activities:
_Monitoring of the nesting areas and habitat protection: This includes a morning survey and a night survey, as well as nest protection, the females and their hatchlings.
_Public Awareness: Education of both tourists and locals about the turtles and the impact of coastal development on the nesting beaches. Volunteers participate in information stations, slides shows in sea turtle biology in hotels and beach patrols.
_Maintenance and day-to-day duties.

At the Sea Turtle Rescue Centre in Athens arrive turtles usually caught in fishing gear or injured by speedboats and fishermen. Once the turtle has recovered, it is put back into the sea.
The duties of the volunteers include preparation and administration of food, operation of the sea water supply systems, carrying and cleaning the animals, as well as cleaning the facilities and equipment. Volunteers also participate in collection and transport of injured turtles, and public awareness activities.
