I don't think you can, so you're going to have to go through the Rock Tunnel. I know it's kinda hard, but it only took me around 5-10minutes. Go to http://www.gamefaqs.com/portable/gbadvance/file/918915/33196, it's a guide through the whole entire game! Hope this helps or google map of rock tunnel and it gives you step by step directions to get through
You'll need a Pokemon that knows cut, a Pokemon that knows flash, and a Pokemon that's good against the ground-type. Go through diglett cave to get to route 2, and look in one of the houses there. Get flash from one of the people and go to rock tunnel. use flash.I hope this answered your question. I really don't have the time to tell you how to get to the exit, but just think of it as a larger Mt. moon.
You will need to get a Pokemon that has the ability to learn Flash. Once you do this, the path will be light through the tunnel.

If you head East from Cerulean City (you need Cut) and then South you will encounter the Rock Tunnel you need to pass through to continue to Lavender (then onto Celadon). To pass through the Rock Tunnel it's recommended you use Flash. (It is passible without.)
Lavender town can be found after travelling through the Rock Tunnel (which you need Flash). Geographically it is east of Saffron City and south of the Rock Tunnel.
