The central sections of the Galilee are among the most beautiful parts of the country. The partially terraced limestone mountains are covered with remains of forests, areas of grain, vines and fruit-trees. Fruitful valleys largely covered with olive groves break up the mountain area. The Jarmak, the loftiest mountain range in Galilee covered with oaks and terebinths, grazing areas, fields and vineyards, rises more then 1,200 metres above sea-level. This area, which is the highest in the country, is intended for a National Park. From the destruction of the Second Temple until the Arab conquest, Central Galilee was the chief centre for the remaining Jews of the country.
