The only Bahai site in Israel I've been to is the Bahai Temple in Haifa. It's situated atop the Carmel and overlooks the harbour and the German Colony. The gardens follow the "falling" type, meaning they literally cover the entire sloap of the mountain. You need to reserve a guided tour in which you get to hear about the Bahai faith. This is the only way to visit the site but these visits cost nothing. Disappointingly, you are only allowed to step downhill as stepping uphill is reserved for Bahai pilgrims.
