If you go to Lebanon you really should take the advantage and explore a bit of the country. During my trip to Beirut I also went to the city of Harissa and Byblos and that are two places I strongly recommend to visit.
I just returned from a weekend trip to Beirut, Lebanon. It felt like whole another world but it was very exciting. And a huge contrast to my everyday life. Just as I like traveling to be. Not all the times but sometimes. If you are looking for a destination that not all around you has been to Beirut is the place to go.
