Where can you find ampharos in crystal?

In Pokémon Crystal, Ampharos is the evolved form of Flaaffy, which itself evolves from Mareep. You can catch Mareep in the National Park, as well as on Route 34 and Route 42. After obtaining Mareep, you can evolve it into Flaaffy at level 15 and then into Ampharos at level 30. To find Ampharos directly, you will need to encounter it in the wild in the later rematches in the game or through trading, as it is not available in the wild in its final form.
