Nobody says the tunnels will be a rape dungeon, there would be access to Mars's surface but it makes sense to avoid the need to ship in building material when available. You could build access to the surface with a hanger for land rovers & acess by those space suits where you access by a back hatch.

Since it's underground you'll have less pissing & moaning from people who worry about destroying mars.
