The Lower Galilee consists of three different regions which differ in their geological structure:
The central Lower Galilee consists of low mountain ranges which extend from east to west with several valleys in between; south of the Beit Kerem (Šagor) Valley is the Shagor mountain range, then Sakhnin valley, Yodfat range, Beit Netofa Valley, Tur'an valley and range, Nazareth range, and Ksulot () valley. In the western part of the Lower Galilee there are several low hills (200–300 meters) covered with Oak tree forests, the central Lower Galilee region is more mountainous and the eastern Lower Galilee region turn into flat basalt mountainside reaching heights of 300 meters above sea level which extend from northeast to the southwest.
Although the landscape of the Lower Galilee is less dramatic than that of the Upper Galilee, it is greener, more peaceful and quiet. The Lower Galilee is more accessible to the majority of Israelis (less than a 2-hour drive from the Tel Aviv area). Much of the produce farms of Israel originates in the Lower Galilee, especially in the Jezreel Valley and the Beit She'an Valley.
Until 1932 the settlements in the eastern Lower Galilee were based solely on spring water which existed in proximity to the villages which were only enough for home use and therefore it was not possible to have irrigated agriculture in the Lower Galilee at the time. In 1932 the first Well drilling was done in the Yavne'el Valley which supplied irrigation water to Yavne'el. In 1942 a water pipeline was constructed from the Sea of Galilee to the village which as a result extended its amount of agricultural lands, which were based mainly on the new water sources, despite the relatively high cost of water at that time. During the first decade of the State of Israel the villages of the Lower Galilee were involved in a constant struggle with the government demanding that the government would solve their water problems. After several local Well drilling attempts made during those years failed water pipelines were laid from the Sea of Galilee to all villages in the Lower Galilee.
