Solo Travel: Beirut > Jerusalem > Beirut

If you review my post #5 you'll see it's a huge problem if you have an itinerary that includes Tel Aviv prior to entering Lebanon. If Lebanon authorities know (or even suspect) you've been to Israel or are going to Israel in the future you will be denied entry.

Your option #1 is fine (It's Amman by the way) as long as you have no evidence of a future visit to Israel (guide books, hotel reservations, etc.) in your possession when you enter Lebanon.

Good luck.

Have just come back from Israel and planning to head to Beruit in a few weeks - having known this in advance I asked the border crossing (King Hussien bridge/Allenby Bridge) to stamp a separate slip because I plan to travel around the middle east. It was no problem at all and the immigration officer simply stamped another form that they have under the counter. I believe this process is quite normal and you shouldn't worry too much about it.

Make sure you have NOTHING that indicates you were in Israel - no Egged bus tickets used as bookmarks, no Tel Aviv hotel receipts, no "I went to Masada" T-shirt... Any of those things will get you denied entry to Lebanon.
