It is according to you (depends what you like: e.g: Theater, dancing, travelling, diving, swiming, hiking, sport, resting, food..... ). Israel is a small country but with lot of action and a veriety of choises. If you decide to come to Israel. contact me, be more specific, and I'll try to assist you.
