In Pokemon Diamond, a very good place to go is North of the Fight Area. All of the many trainers have level 45-60 Pokemon.
Go to the Fight Area after beating Champion Cynthia and the Elite Four. Then you can go to the dock in Snowpoint City. Then you will arrive in Fight Area. Then in the North, there is a fisherman.
