Tzfat (aka Safed)
At 3,000 feet above sea level, Tzfat is the highest city in Israel. It is reputed as the center of Jewish mysticism (aka Kabbalah).
Kabbalah which dates back to the 12th century was formed as a reaction to formal rabbinical Judaism and is essentially about reading between and around the lines. Each letter and accent of every word in the holy books has a numerical value with specific significance offering added meaning to the literal word. You can walk around the city and enjoy many of the Kabbalah learning centers and artist shops.
