I believe it was either route 223 or 224...I think 223...
There is a route to the left of Viridian City that you can take in order to get to Victory Road.
In Pokemon Diamond and Pearl, Victory Road is only accessible from Route 223. Surfing north from Sunyshore City, the player can Surf up Route 223 and come to a waterfall. There is a cave opening at the top of the waterfall which leads to Victory Road.
It is located north of Route 223 and west of Route 224.
Make your way through route 223. When you get to a Pokemon Centre, walk into the cave on the left and you will be in victory road.
In victory road or route 224 right outside of victory road hope this helped (you don't need the national dex)
