Cinnabar Island HGSS · Kanto Town
Cinnabar Island sits off Kanto’s southwest coast, reached by surfing south from Pallet Town on Route 21 or west from the Seafoam Islands on Route 20. In HeartGold and SoulSilver a volcanic eruption has wiped out the town, leaving only a rebuilt Pokémon Center, and Blaine has moved his Gym to the Seafoam Islands. Blue can be found here before his Viridian Gym opens.

Tips
- The island’s items, including the Magmarizer on the volcano, need Rock Climb to reach.
- The Magmarizer lets Magmar evolve into Magmortar when traded while holding it.
- Look for Blue near the volcano; his Gym in Viridian City opens once you hold the other seven Kanto Badges.
- Head east on Route 20 to the Seafoam Islands to find Blaine and the Volcano Badge.
- Fish with the Super Rod for Chinchou, Shellder, Tentacruel and Lanturn.
