Hurst Haven rises in a forest south of Cinderford Lane and flows a southerly course. Turning southwesterly around the neighbourhood of Carters Corner, Hurst Haven flows a southeasterly course into the Pevensey Levels just west of the village of Magham Down. After receiving the waters of Iron Stream, Hurst Haven turns south before curving west and receiving the waters of Down Sewer and Horse Eye Sewer before joining Glynleigh Sewer to form the Pevensey Haven.[1]
