A nice trail at Menashe Heights woods.
Drive from Ein Hashofet, on road 6953, to east (Mishmar Haemek) for 1 km, after Giuara junction watch on the left side for the blue mark. Road 6953 has a lot of serpentines descending from Menashe Heights to Izrael Valley through Hashofet Forest.
Another possibility is on road 66, between kilometers 27 & 28.
