A close second with Masada as the top non-Jerusalem site in Israel, and that's because while Masada looks epic it doesn't have much else going but at the caves here you can explore so much, get a good idea how they used this place with limited availability and it can take a long time to hike everything.

The second art cave in the "back" is currently collapsed but the nearby shop gave me a nice picture to understand what I'm missing. It's probably possible to descend and look around but it's not a wise idea. The one next to it is already pretty great. I also really enjoyed getting led through a cave with odd markers that I never thought would bring me back out but it really did and on the way you get to see the presses, some kind of flooded area and entryways that seem unnatural.

Definitely not something to miss on the trip.
