I don't know exactly how long it took me, but I didn't quite make it all the way to the top for the sunrise... but I was only one flight of stairs down from the top when I watched the sun come up over the Jordanian Mountains and the Dead Sea below. It was truly an amazing sight. And I still had time to get up the last flight to enjoy the sun climb over the ruins at the top. I was exhausted and exhilarated at the same time, and for not the first or last time when in Israel, amazed that I was even there and that this was even happening.
Masada was gorgeous, of course. Hike to the top and then lots of history lessons, which doesn't really count as hiking, but hey... the scenery was legendary.
