First visit: March 2004
Subsequent visit: February 2006, August 2012.
Visited: Manama, Tree of Life
Bahrain is small and there is little here to keep your interest. The capital Manama has an interesting market but nothing like other Arab places, while the promenade is second rate compared to Doha or Dubai. The Tree of Life, however, was almost like a religious pilgrimage for me, and it is at the other side of the island so you can say you have seen the whole country while driving down there. Bahrain is best seen on a day transit while flying somewhere else with (crappy) Gulf Air.
Highlight: The amazing Tree of Life, a huge tree standing alone in the middle of the desert.
