The Voya Nui Bay was the bay that Voya Nui's landmass encircled. The bay used to be filled in with land created by a volcano, upon which the Matoran city of Mahri Nui was built. However, Mahri Nui eventually broke off and sank, taking its inhabitants with it. Afterwards, the Matoran still on Voya Nui threw flowers, gifts and supplies into the bay as a tribute to their deceased friends, not knowing that they were actually still alive.
It no longer exists after Voya Nui slammed into the Southern Continent.
