In the underwater sealed cave and in the three regi caves
That's what the designers wanted.
In order to open the Regis caves in Pokemon Emerald you first have to go to route 134 and dive into the cave. When you are in there use dig. The first Regi cave is located in the desert.
In Pokemon Ruby, Sapphire and Emerald the Regi Trio can be found in three tomb-like caves throughout the world. To get to them you need to unlock the caves themselves by solving the puzzle in the Sealed Chamber. Each of the caves housing the Regis have their own little puzzle you need to solve to unlock the inner chamber to access the housed Regi.
