There is a permanent portal somewhere under the Black Spires in the Five Shires, created through the use of blackflame and named "Ring of Fire", leading to Halfling lands in some other world -- the GAZ suggests Forgotten Realms or Greyhawk can be reached by rings of fire, but doesn't specify which is reached by this specific portal.
There's also an unnamed portal in Oenkmar, leading to either Forgotten Realms or Greyhawk.
