The Pool - Back Access is a location in Luigi's Mansion 3. It is found in the Fitness Center on the thirteenth floor of The Last Resort. It is connected to the Pool and Gym Lobby.

When Luigi first enters the Back Access before the boss battle, he won't be able to enter the Pool since it's blocked by a bunch of towels. The is a treasure chest near the bench that Luigi can use the Dark-Light Device to reveal and obtain bills and coins. There's also a trash can near the stairs filled with Gold Bars, bills, and coins by using the Dark-Light Device.
