So the Nether hub can be quite confusing if you're not sure of which hallway is the portal you're looking for. To help that, I decided to make a list with the portals in each hallway! They're ordered from closer to further from the four main portals.
ORANGE HALLWAY
Public Skelly XP Farm
AuroraKnight's Base (Private)
Geo's Mining Outpost (Private)
Heatherly's Base (Private)
Romy and Chappy's Base (Private)
PURPLE HALLWAY
Public String Farm
Kettai's Base
DrParan0ia's Base (Private)
Maysey's Base Mush Isle (Private)
Public Mush Isle!!!
Ice Spikes Portal (bring a minecart)
GREEN HALLWAY
Public Guardian Farm
Whiter Skull Farming Area (not a portal - bring a minecart)
BLUE HALLWAY
GeoTheory's Base
Public Jungle Biome
Swarles' Base
Joe's Big Base
Please let me know if I missed something, misplaced a portal location or if there's a new portal so I can update the list!
