Talk to the Fossil Maniac he lives to the left of fallarbor town then go to the desert to find Mirage Tower.
mirage tower only appears in pokemon emerald.
first you have to go in the desert then go right about 5 steps then go down until you see the mirage tower and come in the left way of the desert
wait for the old guy in the house in southeast Pacifidlog Town to say OMG i see Mirage Island Then you use SURF and go east from Pacifidlog till you reach Mirage Island

its useless to get there..... still - enter the desert many times form Mauville.As you enter , walk a few steps forward. You will find a black person in blue dress (rock Pokemon trainor) .To his right side, you should see the mirage tower
It is not available in Sapphire, but it is in Emerald. It's in the desert region on route 111. If you come up from Mauville City the Mirage Tower will be close to the entrance of the desert area. Sometimes you can see it, sometimes you can't so just keep going back and forth until you do.
You need mach bike
in the dessert where mirage tower is
the go

He is in the northeast house in pacifidlog town (the floating town between routes 131 and 132).
Go to route 119. stick to the top of the water and there should be rocks that make a path. follow the path until you get to mirage tower. youtube helps to kiddo
