Get Lugia's HP down to a sliver. Next, put it to sleep or paralyze it(You can switch these two steps around, but that's not a good thing if you plan to put it to sleep). Finally, just start chucking Balls at it. If you got your Master Ball from Prof. Elm, or from the Lucky Number Radio Show from matching all 5 numbers in your/a friend's Pokemon ID number, you may use that. If you have atleast 10-20 Ultra Balls, good luck. If you have Great Balls, got a tiny chance. If you have Poke Balls, you're out of your mind! If you're lucky enough to catch it with a Poke Ball, you're either using a GameShark or you are just lucky.
NOTE: IF YOUR LUGIA HAS A PINKISH/PURPLEISH STOMACH AND TONGUE, YOU JUST ENCOUNTERED A SHINY LUGIA(1 out of 800)!
go to whirl islands
You can't get Dark Lugia in Pokemon Silver, Gold, or Crystal. You can get Dark Lugia in Pokemon XD though. For Pokemon Silver, Gold, and Crystal it is just the regular Lugia.
The best way to catch the Lugia is through the Caves. You must have a silver feather before entering. Navigate the path until reaching the waterfall where the Lugia is located then engage in a fight using your best level 40 or higher Pokemon.
In the whirl islands.
you go to the third gym you go up you go to the grass and you randomly walk around and voila! dark lugia if you want shiny do the same thing but release your mew and mewtwo and there is shiny lugia.
The Silver Wing in Pokemon Silver lets you interact with Lugia in the Whirl Islands to fight and catch it. Lugia can be found in the deepest part of the Whirl Islands.

You will only have one chance to catch Lugia so if you make it faint, you will not be able to catch it again. However, if your whole party faints, you will go back to the Pokemon center and you can battle it again.If you failed to catch Lugia, you can still trade for it.
Lugia is in Pokemon Silver, Soul Silver, and Heart Gold.
