Subrosian Portals are objects from The Legend of Zelda: Oracle of Seasons. These small blue portals can be found sporadically throughout Holodrum. When Link steps on one, they teleport him to a corresponding location in Subrosia. Likewise, the same portals can be found in Subrosia; they will teleport Link back to Holodrum. Link first encounters a Subrosian Portal while he is following Rosa north of the Eastern Suburbs.
The Subrosian Portals are found at the following locations:
- Eyeglass Lake (Fenced in area west of Woods of Winter)
- Eyeglass Lake (Accessible in any season when the lake is flooded, except summer)
- Spool Swamp (South of the entrance to Poison Moth's Lair)
- Mt. Cucco (North of Sunken City)
- A cave in Horon Village (The lowest part)
- Subrosian Volcanoes (Below the Volcanoes themselves)
- Subrosian Volcanoes (Preceding Sword & Shield Maze)
