Hidden passage

The hidden passage was a long indoor tunnel leading to the Great Hall of Thráin, the lair of Smaug in the Lonely Mountain.
The tunnel was about five feet high as with the Side-door and ran about two miles and was entirely smooth and followed a gentle but never deviating downward slope, down to the Lower Halls of the mountain realm.The Hobbit, Chapter XII: "Inside Information"The Atlas of Middle-earth, The Hobbit, "Lonely Mountain"
== History ==
The hidden passage as with the Side-door and its key were created at an unknown time by Thrór and his son Thráin before the fall of the Lonely Mountain. Their reason for creating it was unknown but literature points toward a means of escape in case of siege or other emergency.The Hobbit, Chapter I: "An Unexpected Party" Unused for 171 years, the hidden passage was rediscovered along with the enchanted Side-door by Thorin and Company on Durin's Day on October 30, 2941The Atlas of Middle-earth, The Hobbit, "Introduction" and the Hobbit Bilbo Baggins was charged with exploring it. Traveling down the hidden passage for hours, Bilbo conferred with himself as to the reason for him doing this and going on this adventure to begin with, and that the Tookish part of him was at work. Towards the end of it due to Smaug, the hidden passage grew warmer and warmer until it became quite hot.
After Bilbo emerged from the hidden passage with news of Smaug's anger, the Dwarves feared he would find out where they were and kill them so they all entered the hidden passage and sought refuge in the mountain. Smaug indeed did find were they came from and smashed against the mountain, destroying the Side-door and sealing Thorin and Company within the hidden passage.The Hobbit, Chapter XII: "Inside Information"
