Mount Gerizim, the tree-covered slope southeast of Nablus, features a terrific view of the Shomron Valley. Since the 4th century BC, it has been the holy mountain of the Samaritans, who revere it as the spot where the original Ten Commandments are buried and where Abraham prepared to sacrifice his son Isaac. The Samaritans, an Israelite sect who were excommunicated in biblical times, are distinguished by their literal interpretation of certain scriptures (refer to the Introduction to the Region for more details). The highlight of the Samaritan observance of Passover is the sacrifice of sheep atop Mount Gerizim. Tourist buses from Jerusalem and Tel Aviv bring visitors to witness the bloody rite. The hike up the mountain is arduous, but taxis can be hired for about NISI 5.
