You can make use of an Grand Exchange shortcut on the northwest wall, go on an excursion on the minecart that runs through Ice Mountain Dwarven Mines, or utilize the minigame group finder to make an appearance outside the building.

Then, run down the ramp using a bucket filled with water or ice gloves. Let your bars cool down before you bank them.
