I know this answer comes quite late, but the other answers are wrong.Īlftand isn't the only way in. Since Mzark doesn't have enemies to begin with, it will always be enemy free. While several of these locations are fast-travelable-to, the Tower of Mzark is likely to be the quickest way into Blackreach, as it's associated 'wing' is quite small, with no enemies.īy contrast, the Great Lifts, like Alftand, or Mzinchaleft, still have goodly portions of dwemer dungeon ruin between their elevator and blackreach proper, which will replenish their enemies (and loot) over time.
These supplemental entrances are initially barred with a gate, and therefore inaccessible before you've started spelunking.Īs per the UESP, here are the potential entrances into Blackreach: As you adventure below Blackreach, though, you will discover 4 additional entrances via elevators back up to the surface.
Initially, you can only enter via one of the 'Great Lifts': Alftand, Mzinchaleft, or Raldbthar, and only with the Attunement Sphere from Septimus Signus.
