Israel puts very different places within a short drive of each other: Jerusalem with sites central to three religions, Tel Aviv as a coastal city with a Bauhaus core and beach culture, and the Dead Sea and Negev desert an hour or two further. The contrast between Jerusalem and Tel Aviv is the one most visitors remember.
The guides here cover Jerusalem, Tel Aviv and Israel overall. Sabbath observance affects transport and opening hours from Friday afternoon to Saturday evening, which needs factoring into any itinerary. Religious sites enforce dress codes. Security conditions in the region have changed repeatedly and vary by area, so current government advisories are the right source for whether and where to travel, not a destination guide.
