Here is our planned route in Israel. The very last bit that follows Hwy 12 along the Egyptian border into Eilat is likely going to have to change as that is where the attack from Gaza via the Sinai occurred last month.
The whole route is only about 600 miles — Israel is a small country — and considering that we have more than 3 weeks for our trip, we will have plenty of time to stop and explore along the way.
