Minecraft wiki entry for Defeating_pyramids, associated text: If the entrance is in plain view, it's usually easiest to enter through the entrance. Otherwise, you can either excavate the entrance, or just bust a hole in the wall and go through that way. If hardly any of the structure is visible, it may be best to go through the roof. It is strongly recommended to enter on the 2nd or 3rd floor and make your way down, so that when you enter the building, arrows shooting at you is not the first thing you must deal with.
