How do you get into the underground base at the restricted area on Grand Theft Auto San Andreas?

Answer 1

You go to the building by the Baseball feilds and u go to the top level of the building and u go into it with a jetpack and then go to the white part once your in the building(glitch) and go down with your jetpack.Make a point on the map at restricted area and fly there with your jetpack(you can`t go above ground once you go under everything). When u go through water you may run into some problems being you can`t gp through it, the solution to that is go way under(not to far because you teleport where you are)and continue to the resricted area.Once your there you go to where the underground area(you know what i mean) and lower your self until you teleport. Enjoy being under the restricted area
