First off, sorry for the Hiatus (School and life in general), but I came here because I don't know how to reach Lavaridge City. I got Alpha Sapphire for Christmas and had an easy time until now. I am asking those who have beaten Flannery on how to reach it easily.
You do have the vast internet at your disposal, but I suppose coming here for reliable info is good. ;)
I'm not sure where you are, so I'm going to assume you've made it north of Mauville to Routes 111 and 112.
Go through Fiery Path on Route 112, it's up the stairs on the mountain-like area, to the left.
It's pretty straight forward, just go through the routes, doing what people say, and once you finish the Meteor Falls stuff, May/Brendan will take you back to Mauville (so you don't have to backtrack).
The cable car lift on Route 112 will now be available, it's on the same little mountain area as the entrance to Fiery Path.
You have have to deal with Team Aqua first, but once you're done with them, you can go down through Jagged Pass, and after you exit, to the left is Lavaridge.
Bulbapedia is very reliable with info, as is Serebii, so for any future info, it would be a good idea to check those.
Here's the ORAS walkthrough on Bulbapedia.
