The stunning Baha'i gardens overlooking the city of Haifa. It consists of 18 different terraces all built on a very steep hill. To visit them you have to book in advance, which we didn't do. Fortunately it is possible to go to the gate and sign in on a waiting list. If somebody doesn't show up you can then take their place. We didn't have to wait long as there were people missing in the first group that left and we were able to replace them.
