Gelli Camp is an oval or subrectangular enclosure, about 42m north-south by 36m, defined by a bank and ditch, set upon the north-east tip of a slight ridge, having a north-west facing entrance. A second, possible, enclosure, largely denuded, lies about 40m to the south-west (Nprn400320).

A possible counterscarp is apparent on the south; a ditched/banked approach leads at least 64m to the north-west, where it is obscurred by the railway.
