The real problem here is the spoilers, not the access to the underdark itself. In a perfect world, every player starting the game should not even be aware they can go to the underdark. It is such a mythic place for surfacers. They have to struggle hard to reach it if they so want to. And the only thing they know, really, is the fact it's damn dangerous but full of treasures.
So the best thing is to be patient. Of course, there are some players out there who would prefer to get to the final boss of a game when they just started it, but in a RPG like this one, it's like missing everything it has to offer.
