A trainer in Violet City will trade you a Bellsprout for one. Alternatively, you can catch Steelix in the Cliff Cave on Route 47 at Lv. 23. Breed with a Ditto, or another Steelix, it will hatch into an Onix with no name, unless you name it yourself. Source: I have the Guidebook.
A trainer in route 23 has a rufflet
To get to Viridian City simply travel south of route 23 and east through route 22. If you are actually stuck in Route 23, as in you can't exit via the south and don't have Fly, you may have encountered an undocumented glitch and sadly will need to restart the game.
AnswerKurt is primarily in Azalea Town, in his house near the Pokemon Centre. However, if it is your first time visiting the area, Kurt can be found in Slowpoke Well, on Route 23.
The earliest one you can catch is in the grass just west of Viridian City, on the way to Victory Road (Route 22). Aside from there, there's Route 3 (between Pewter City and Mt. Moon), Route 4 (between Mt. Moon and Cerulean City), and Route 23 (between the reception gate and Victory Road).
Between Viridian City and Victory Road... What about route 23? Is there even one?

In Route 3,4, and 23.
Bellsprout evolves at level 21 if I'm not mistaken, might be 22 or 23, but I'm pretty sure its 21.

There is no route 23 in Pokemon gold but if you mean heart gold it is the north exit of indigo plateau south exit of route 22 and west exit of victory road.
I think you go to route 23 and it will say to jump to route 28
You get Vullaby on Route 23
