You have to first go to Celadon City and beat Giovanni to get the Silph Scope. You then go to Lavender Town and beat Marowak and the Rocket people to rescue Fuji. He gives you the Pokeflute that awakens Snorlax and allows you to go to Fuscha City.
WARNING: THERE ARE ONLY 2 SNORLAX IN THE GAME SO CATCH 1
