Israel really has a thing for lookouts. If there is a prominence, it has a lookout on it. But who can blame them when this is the view?
The region was first settled 5,000-6,000 years ago. It was conquered by the Egyptians 3,500 years ago, and then by the Philistines. When King Saul killed himself in battle on Mount Gilboa rather than be killed by his enemies, the Philistines recovered his body and hung it up in the city, which by then was known as Bethshan or Beit She'an (see 1 Samuel 31). In about 700 BC the city was destroyed by fire, then rebuilt by the Greeks, and around 400 AD during the Roman era, it reached a peak of 30,000 to 40,000 inhabitants. It is the remains of that era that comprise the Beit She'an National Park.
Before we went to Beit She'an National Park, we stopped at the Beit She'an overlook, which has a great view of the junction of the Jordan River Valley and Jezreel Valley.
It's a popular place among the locals. We saw a few groups of picnickers having a good time:
We made our way back down to the valley, passing the ruins of what Wikipedia says is a Crusader castle. (Sometimes I get lucky with my random photos):
