This is the Bulbapedia walkthrough for Pokémon HeartGold and SoulSilver Versions. This walkthrough follows the remade Nintendo DS versions, not Pokémon Gold and Silver.
The guide for those can be found here.

Route 21

Route 21 is a straight stretch of water, dotted with sandbanks. You can track down some oddities like Tangela and Mr. Mime in the tall grass before swimming off to the south. There are 12 Trainers between Pallet Town and Cinnabar Island, so take the opportunity to bulk your Pokémon up.


Cinnabar Island

Cinnabar Island

A major volcanic eruption devastated Cinnabar Island a year ago, and only the Poké Center was left standing. Due to this catastrophe, Cinnabar's usual attractions, including the Pokémon Mansion and Cinnabar Gym, were swept into the sea. However, you will find that elusive Viridian Gym Leader on the island, contemplating the power of nature. Talking to him now won't get you anywhere — as you've only won 6 of the 8 badges of Kanto so far, he doesn't consider you a worthy opponent yet. There is still one Gym left to defeat before you can challenge the Viridian Gym — after the eruption, Blaine and his Gym Trainers relocated to a cave in the Seafoam Islands.


Rest your team, and swim east to reach Route 20 and Route 19. Don't forget to bring a Pokémon that knows Strength, too.

Route 20 (west)

Route 20 stretches out to the east, where the water laps against the Seafoam Islands. Fight a few Trainers to earn some easy money and experience, then step inside the eastern of the twin islands.


Seafoam Islands

Two choices: a ladder leads upstairs, an icy staircase leads downstairs. Check the lone rock at the room's north end for an Escape Rope, then climb the ladder to reach the relocated Cinnabar Gym.

Seafoam Gym

The relocated Cinnabar Gym

Blaine and his Gym Trainers, despite being surrounded by water and ice not far away, all still specialize in the Fire-type. The loss of the Gym means that Blaine also lost his quiz machines, but there's a new trick at work here. His six Gym Trainers will not approach you, even if you step in their line of sight. However, they each block part of the path that leads to Blaine, and will not move out of your way until they've been defeated in battle. The central area where the Gym Leader is waiting can only be reached from the western side, because Super Nerd Merle is the only one of the three near the Gym Leader that doesn't block your path upon defeat. Blaine has only three Pokémon with him, but with levels in the mid-50s, they are no pushovers. The most effective moves are of the Water- and Ground-types, so attack with moves like Surf, Waterfall, and Earthquake. Watch out for his Magmar — if you sent a Water-type into battle, its ThunderPunch could make you think twice. Each is holding a White Herb, so all three can avoid stat reduction for a single turn, making Overheat that much more painful.

Seafoam Gym
The Volcano Badge





After you douse his fire, Blaine awards you the Volcano Badge, which give a slight boost to your team members' Special Attack and Special Defense. He also gives you TM50 (Overheat) as a prize.

Now that you've won your seventh badge, climb down the ladder and venture into the icy caves underneath the islands.

The Seafoam Island Caves

The Seafoam Islands

Unlike the original games, the Seafoam Islands are still intact. Bring a healthy supply of Ultra Balls with you, as another legendary is roosting on the bottom floor.





Route 20 (east)

After exploring the icy depths, you re-emerge on Route 20. Surf your way to the east to fight another handful of Swimmers, and you'll soon reach the waters of Route 19.


Route 19

From Route 20, surf north across the waves of Route 19 to reach dry land. As you step onto the Fuchsia beach, you'll see that the workers have finally cleared the road of the boulders that were flung here from Cinnabar's eruption.


Fly back to Cinnabar Island and talk to Blue. Now that you've won the seven other badges of Kanto, he finally considers you worthy to enter the Viridian Gym. Once he leaves, fly back to Viridian City.
