Yawning Portal Map

Cartography by Faxfire

Both the adventures Waterdeep: Dragon Heist, and Waterdeep: Dungeon of the Mad Mage make the tavern the Yawning Portal a focal point. It is the titular feature of the anthology book Tales from the Yawning Portal. Yet none of these sources provide a map of the establishment. Justin Alexander provides a great history of the tavern on his blog in a series of posts connected to his remix of Dragon Heist, which influenced me to draw my own version. I've included the extra major element of a stage because I think it offers unique roleplaying opportunities for players. The upstairs levels are not detailed, because I think it's largely unnecessary. Those using the map should note that the black squares around the literal yawning portal are the supports for the upper levels and their balconies, which overlook the famous entrance to Undermountain. 

My handdrawn version above is intended to provide a good visual representation that you can use in the intro scenario for Dragon Heist, or provide a real backdrop for your breaks from Undermountain in Dungeon of the Mad Mage. Enjoy!
