Find the Route to Duck City
Use Jumping to take the ledge beyond Waterfall Village and follow the northern route.
In-game objective
Now that you can jump you should be able to jump up the ledge in Waterfall Village. Keep following the path from there and you should reach Duck City
Return to Waterfall Village
Go to 
Waterfall Village after learning Jumping.
Take the high path
Jump up the ledge on the route out of the village and continue north toward 
Duck City. A later travel barrier leads to the solitary-trainer objective; reaching the city itself is tracked separately.
