Succulent Garden

So I am trying to figure out what to do with a couple of places at my house. The first place is by the street (outside the gate) on a hill. I need to do a sprinkler system down there, but I want it to look nice...instead of dead. So I was thinking succulents. Do any of you know anything about succulents? Can they stand full sun all day long? And what about drought tolerant? I don't want to have to worry about it. I have never done succulents, but I know a garden of them can be gorgeous. Any help would be awsome!! Thanks
