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
By walking there from Saffron City or through Rock Tunnel from Cerulean City.
in the rock tunnel, outside of lavender. there is some chick in a green outfit about half way through it.
You have to get through rock tunnel, by going east of cerulean city, through the robbed civilians' house and slashing through the thin tree. Then, you have to fight several trainers, then through the tunnel, and wala! You're down to Lavender Town.
At the time you need to proceed to Lavender Town, the shortcut (passing by Saffron City) is impossible to use. You have to go the long way by heading east of Cerulean City and navigating through Rock Tunnel at Route 10 (requires HM Flash.)
When you get in Lavender Town, go west and you will find a tunnel. That tunnel leads to the Celadon City. You will only get the silph scope and finish the gym there then go back to Lavender to get the Poke Flute.
Get to Lavender Town through Rock Tunnel (or Fly there, but the HM is impossible to get until you have already visited Lavender Town.)
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.
well first you need flash and you go to the rock tunnel and use flash and after you make it through the rock tunnel then you walk down the path and then you are in lavender town!

You can get to Lavender Town via Rock Tunnel from Cerulean City. Route 8, from Saffron City. An underground tunnel, that takes you from Celedon City to Route 8. Or from Fuchsia City.
