On the northern Israeli border with Lebanon is the historical site, Rosh HaNikra. If you only have one day to travel to the north and are attracted to historical and natural sites, I suggest making this trip.
Approximately a three hour drive from Tel Aviv (or, central Israel) is the naturally formed rock formations of Rosh HaNikra. It's situated on the coast of the Mediterranean Sea and features massive rock grottoes, or caves, that have formed over thousands of years and are now easily accessible for touring.
Historically and politically it's an interesting location to visit as a major cross-road in the Middle East. This is where Alexander the Great entered the Land of Israel and it was also a major supply route in WWII for the British. In recent years, Rosh HaNikra became a strategic military point in the Lebanon-Israel war.
It features a cable car to take you from the top of the mountain to the base and also a short movie which is shown in either Hebrew or English explaining the history of Rosh HaNikra.
Don't forget to check out the border gate that looks into Lebanon at the top of the mountain. It's a wonderful photo opportunity!
Pricing (which includes riding the cable car):
Adults NIS 42 ($15 USD)
