Its mountains—Carmel, Gilboaʿ, Aybāl (Ebal), and Al-Ṭūr (Gerizim)—are lower than those of Upper Galilee, while its basins, notably those of the ʿArrābah Plain and Nāblus, are wider and more gently contoured than their equivalents in Judaea.
Samaria is easily approached from the coast across the Plain of Sharon and from the Jordan by the Fāriʿah valley.
