Viridian Forest #3: The first place where you challenge a large amount of guys. Look out for available items sitting around. You can get a Pikachu here!

Indigo Plateau #4: Location of the Pokemon League. Accessible only after you have beaten all eight gyms. Many trainer battles in here and also you can find one of the three rare birds in here, Moltres. To find out how to catch him, refer to the FAQ.

Pewter City #5: Location of Gym #1. Above is a large building, a museum. The building on the right is only accessible by cutting down a tree and walking in. The man in there will give you a fossil, the Old Amber. This museum is also the place to get Aerodactyl, Kabutops, and Omanyte.

Celadon City #6: City with extremely large shopping center. Location of gym #4. On the top floor of the shopping center, they have vending machines that sell three types of drinks. There is a girl up there that if you give her one of each drink, she will give you a different TM. Also in the Slot Machine center there is a man that is standing in front of a poster in the back in a black suit. Fight him and then inspect the poster by pressing A. You will here a *KLUNK* and a stairwell will be opened. This is the Team Rocket Lair. Go immediately down when you first enter the hideout and press A on the pots the plants are in and you will find a PP Up. Here you can get the Silph Scope used for seeing the ghosts in the Pokemon Tower, get other items, and fight in many trainer battles. To the left of the large shopping center is a small road with a sleeping monster blocking the way, this is one of two Snorlaxes. Use the Poke Flute on him once you get it to get by. Be careful! If you're going for all 150 pokemon, there are only two Snorlaxes in the game. Save before fighting him so if you mess up, you can reset and try again. Also there is a tree there. Cut down that tree, go up and to the left, and you will see a house. Go into that house and a girl will give you HM02, which us Fly. Use it on any flying pokemon. This ability puts up a map and lets you go to any city that had a Poke Center that you went into. For example, if you went to Lavender Town and didn't go into the Poke Center, that town will not be an option. If you go to the bottom right of the city, and proceed up the right side of the wall into a narrow passage and press A against the tree you see there, you can find a PP Up.

Mt. Moon #7: This is a cave that will take you from the outskirts of Pewter City to the outskirts of Cerulean City. You can get some items scattered around in there. One of four Moon Stones is in here, next to the man who challenges you for one of the fossils. Go into the narrow path and press A on the end, and you will find a hidden Moon Stone. The man who challenges you for one of the fossils will give you only one when you beat him, either the Dome Fossil or the Helix Fossil. t in the Poke Center near the entrance to the cave, a man is inside the there that will sell you Magikarp for 500 Yen.

Cerulean City #8: Location of Gym #2. At the bottom of the city is a bicycle shop. The man who owns it will give you a bike for free if you give him the voucher (see Vermillion City #12 to get the voucher). To the north of here is a bridge and a path to Bill's House with lots of challengers on it and an item. In Bill's House, you need to change him from a pokemon back to himself. When you do this, he will give you the S.S. Anne Ticket. To the upper left of the Poke Center is a house with a man that will tell you what every badge for pokemon does. Go out of his house and to the right on his patio there is a hidden Rare Candy there. Also, in the house next to the Poke Center is a man that will trade you a Jynx for a Poliwhirl.

Rock Tunnel #9: At the entrance to the Rock Tunnel, you notice a small river way extending down on the right side of the screen. Return here later when you get swim to get to the Abandoned Power Plant. In here there are items, some items are actually Voltorbs, disguised as an item. Also in the Power Plant you can face one of the three rare birds, Zapdos. To catch him refer to the FAQ. The Rock Tunnel without the ability flash is completely black. To make it light, use HM05 on a Pokemon like Clefairy, Pikachu, or Jigglypuff. To get HM05, there is an area next to the trail that leads to Viridian Forest, that is blocked off by trees. Use tree cutter and go into the house and talk to the men inside, they will give you HM05. Also above that house is another house. In there, a boy will trade you an Abra for a Mr. Mime. There are many guys to face in there in the Rock Tunnel, but no items.

Saffron City #10: The only way in here is to give the guard a drink. Go to the top of the Shopping Center in Celadon City and get one of the three drinks (anyone is fine). He will then let you in. Location of Gym #6. There are two sections of the gym, the first section on the left is where you can get one of two monsters, but only one. The monsters you can choose from are Hitmonlee and Hitmonchan. There is one building where you must beat the Team Rocket Leader again. In this building is also the Master Ball, given to you by the man when you defeat the Team Rocket Leader again. By doing that, you now have access to the second part of the gym where you can get the badge for Gym Boss #6.

Lavender Town #11: Location of Pokemon Tower. Nothing of much importance here. Man in bottom right house will rename your Pokemon if you are the original owner. To the trail on the left are some challenges and a house that has an underground trail to Celadon City (#6). To the trail to the south of Lavender Town, are challengers. Go farther south and there is a sleeping monster blocking the way. You need to get the Silph Scope to view the ghosts in the Pokemon Tower (Celadon City, #6). After beating the Pokemon Tower, the man at the top will give you the Poke Flute. This can be used to wake Snorlax, the sleeping monster blocking the way to the south. This path will now lead you to Fuschia City (#13). On the way down to Fuschia City, there is a house, the only one along the way. In here, a man will give you the Super Rod. You can catch a variety of Pokemon with this.

Vermillion City #12: Location of Gym #3. To the immediate left of the entrance to Vermillion City is a Poke Center. To the left of that is a house, is another. Go into the farthest house to the left. In here, a man will give you the Old Rod. This can only be used to capture Magikarp. To the south of the city is a pier with large Cruise Liner that is docked. On the boat are many challengers in the rooms, which also have some items in them. The captain of the boat will give you HM01, which is Cut. If you have beaten all the guys on the boat and he will not give it to you, make sure you don't have your 20 item limit all the way full. Cut can be used on monsters that appear as a flower/four-leaf clover under the Pokemon category when you press start. Above and to the left of the gym, there is a house with six people in it, two of which are pokemon. Talk to the man in a black suit and had on the top left of the house, and he will give you the Voucher for a free bicycle.

Fuschia City #13: Lots of things to get here! Location of Gym #5. Two houses to the south, near the entrance to the city. The one on the left is the house of the Safari Zone director. He will give you HidenMachin04, which is rock push ability when you find his Gold Teeth in the Safari Zone. In the same house as the man who gives you HM04, there is an item blocked by a rock. Use rock push to get the item. In the house next to the Safari Zone director's house, there is a man that will give you the Good Rod. With this you can catch two different types of water Pokemon. To get HM03, which is swim, you need to go into the Safari Zone. For 500 Yen, you get 30 Safari Balls (the equivilant to Great Balls), and 500 paces to move. For an example of a pace, lightly tap any direction and you will move one square, which is one pace. Don't worry, 500 is a lot. In the way back of the Safari Zone is a house with many statues in front of it. This is the house where you get HidenMachin03. There should only be one man in there, and the inside should look metallic, unlike the other houses in the Safari Zone. Be sure to do the Safari Zone a lot, 500 Yen is great for 30 Safari Balls and there is a large variety of monsters. Be sure to also stock up on Ultra or Great Balls while here (Ultra Balls are the best). If you're having trouble catching pokemon in the Safari Zone, just keep trying. There is no special way to guarantee a catch, except to just to keep trying. Expect to spend quite a sum of money to catch pokemon like Kangaskhan or Tauros.

Seafoam Islands #14: To get here, you need to use the swimming ability given to you by the guy in the Safari Zone (see Fuschia City, #13). There are some guys to oppose while going there. When you get to the islands, the only thing there are two cave entrances, and only one is accessible, the other is the exit that leads to a trail that goes to Cinnabar Island (#15). Bring some Ultra Balls and Great Balls along because 95% of the monsters you face are new. You can get Ultra and Great Balls in Fuschia City (#13). To my knowledge, there are no items or people to challenge in the cave. There is though, one of the three rare birds here, Articuno. To get him, refer to the FAQ.

Cinnabar Island #15: Location of Gym #7. There is also a building there that has many assorted items scattered around in there, with many guys to face, and also many Pokemon not available before, like Koffing and Ponyta. Also here you can bring your fossils to one of the scientists in the building on the bottom left of the island. Give the man one of your fossils, go to the Pewter City Museum, and look at the fossil exhibits. Then, return to the scientist and the fossil will now be a pokemon depending on which fossil you chose earlier in the game while in Mt. Moon. After beating this gym, go back to Viridian City (#2) and beat Gym #8 to get to the Indigo Plateau.
