Well it depends if you want to find one for your pokedex or actually catch one. A swimmer lady has one in the sea before victory road.
While if you want to catch one you will need a good rod. You go to the nearest river to the power plant and use it there the first evolved form of Lummineon Finnineon will be there, catch one and train it and it will evolve to be a Lummineon and level 20-30 i don't remember exactly.
