St Gennys, (Cornish: Sen Gwynnys), is situated in the Deanery of Trigg Minor and the Hundred of Lesnewth. It is bounded on the north by the sea and Poundstock, on the east by Jacobstow and Warbstow, on the south by Otterham and St Juliot, and on the west by the sea. The name comes from St.Genesius, the patron saint of the local church. This small village is on high cliffs on the north Cornish coast overlooking Bude Bay; it is remarkable for its uneveness. Its surface consists wholly of lofty hills and deep valleys. The High Cliff, near Crackington Haven measures 735 feet above sea-level. There are three pointed headlans jutting into the sea from this parish, namely: the Cambeak, Dizard Point and Castle Point.
Crackington Haven is situated at the mouth of a picturesque valley which divides the parish in two, each part supporting a thriving Methodist community. Wrecks are said to have supplied much of the building material of houses in the past but now there is more interest in rescues, the Bude Lifeboat being responsible for saving many lives.
The villages of the parish are Crackington, Roskear, and Penkuke.
