The Ma' Daerah Turtle Sanctuary on the coast between Kerteh and Paka was established by the fisheries department to ensure their survival here. The turtles nest on this protected site between April and September, and although not open to casual tourists, volunteers are very welcome. In the summer months you can spend a weekend helping to monitor turtle landings, collecting eggs for transfer to the hatchery and releasing hatchlings. A minimum donation of RM250 (RM150 for children) is required, and accommodation and meals are provided; book your place two weeks in advance. You could also 'adopt' a nest (RM100) or a turtle (RM150) or help with cleaning up the beach, which usually takes place around April.
