First of all the entrance is free, which is a great plus for a place like this. Very nice view and beautiful gardens. Unfortunately isn't possible to visit the gardens on your own, but you have to wait for the guided tour (available in Jewish, Arab, English and Russian). A big no from my point of view is that you must stick to the high pace of the guides, so you have a very little time to enjoy the place and take some pictures, furthermore, the guide does not wait the group for the explanations, so if you waste one minute to take a photo, you'll miss the explanations about the place, the religion, etc.
