If you're planning to fight the King Titan, this is the route you must take; there is a bridge that leads up to the flat area for the arena. Do not come unprepared.
There are very few places in Ark that can qualify as totally uninhabitable in regards to base building and long term habitation at any level. This is as close as you can come to that. If you can manage it, then you either (most likely) cheated or are a player of truly immense skill and luck, more than deserving of being a king of the game (assuming you can manage to get any time between fighting off the horrors that can quickly destroy anything you can throw at them).
