Olivine Lighthouse Crystal · Johto landmark

Map of Olivine Lighthouse in Pokémon Crystal — 1F (in-game map)

Olivine Lighthouse is the six-floor tower beside Olivine City’s harbour, whose beam is powered by Jasmine’s Ampharos, Amphy. Amphy has fallen ill, so Jasmine waits at the top instead of in her Gym. Climbing the lighthouse and fetching the SecretPotion from Cianwood City is needed before you can earn the Mineral Badge.

Wild Pokémon: None

Tips

Talk to Jasmine on 6F, then Surf to Cianwood City for the SecretPotion and bring it back to cure Amphy; only then does she return to the Gym.
The 5F holds a Rare Candy, a Super Repel and TM34 Swagger, with a Hyper Potion hidden nearby.
Sailor Huey on 2F gives a Protein after one of his later phone rematches.
Bird Keeper Theo’s five Pidgey and Gentleman Preston’s twin Growlithe are among the nine trainers on the climb.
No wild Pokémon live in the lighthouse.
