You need to go through digletts cave but to do that you need to move snorlax to do that help the power plant by giving them the missing machine part which is in the cerulean city gym go into the kanto radio tower in lavendar town and talk to the director he will give you a expn card this will let you listen to kanto radio tune into the radio and find the pokeflute channel play it next to snorlax then beat it or capture it now you can go through digletts cave when you exit the cave go north to reach pewter city.
Once you get to viridian city you head through the Viridian Forest. It is an easy little forest full of bug pokemon, items, and bug catchers. It is kinda like a maze but not a very hard one. Once you get out of viridian forest just keep heading north, and in about 30 seconds you will end up in pewter city. Hope this helps.
You can get back to Pewter City with the HM Fly. You get fly if you go to Celadon City, and go to the farthest left. (Make sure you have a Pokemon with the move Cut.) Go out of the city, and go up, and cut down the tree. Pass through the double building, and when you get outside, there should be a house. Go into and a girl will give you the HM to keep her house a secret. Now, you can fly back to Pewter City! June Days
Through Diglett's Cave which is to the right of Vermilion City.
Remember to get the Kanto Radio Card so you can wake up the Snorlax!
You actually can't. You have to go all the way around from by Surfing from Fuchsia or you have to learn fly.

You can't because you can only catch Oddish on Pokemon red version. the only way you can have Bellsprout on Pokemon red is trade from blue

On the right side.
Do the Pokemon league then go into the cave near pewter city. It's in the somewhere...
From Viridian City you are going to travel north and enter the Viridian Forest. Once you get to the other side of the forest, you continue to travel north and you will enter Pewter City.

If you are speaking of the Old Amber used to revive the Pokemon Aerodactyl, then you will find it in the back of the Pewter City Museum of Science. You need the HM for Cut in order to gain access to obtain it. This is true with Red, Blue, and Yellow. Good Luck catching those 150.
