How to get to the Atlantis dimension

Old method:

Kill all 3 Elder Guardians at an ocean monument, and a portal block will spawn upon killing the last one.
Right-click this block to go to the new dimension.

Right-click the Orb of Atlantis, which summons the portal that you can use to go to the dimension.

Newer method:

From Atlantis v1.3.0-1.17 to Atlantis v1.1.0-1.18.2, you can construct the Atlantean Portal! This portal is made like a regular Nether Portal, but using the Atlantean Core and is lit with a water bucket (similar to the Aether Mod).

Current method (Atlantis v1.0.0-1.19.2+):

Create 12 Atlantean Frames and place them in the shape of an End Portal.
Ignite the portal by right-clicking each Atlantean Frame with an Orb of Atlantis, again, like an End Portal.
Step in and go to the dimension.

The following video demonstrates constructing the portal in current versions of the mod:

Extra tips:

When in the dimension, you will have permanent water breathing, haste, and night vision.
If you spot a fountain-like structure, look under the concrete for aquamarine ore and lapis blocks.
