Red & Blue Route 15
Just east of Fuchsia City, where Oak's Aide hands over the Exp. All once you have caught at least fifty different Pokemon.
Route 15 is in Kanto, with Fuchsia City to the west. In the story you arrive from Route 14 to the east and it comes before Route 19.

Pokemon Encounters
By this stretch Ditto is common at 20%, the easiest place to grab one. Pidgeotto and Venonat share the grass with the same version split as the routes just before it.

ITEMS
The Exp. All, handed over by Oak's Aide at fifty caught, feeds experience to your whole party even when they sit out. TM20 Rage is the other find on Route 15.
TM20 Rage
Rage deals damage, and if the user is hit by a direct attack - any time after Rage is first used but before a different move is used - the user's Attack is raised by one stage.

TRAINERS
More of the same on the road to Fuchsia, where Bikers and Bird Keepers push Poison and Flying to level 33.

Route 15 Guide
Yes. Each version locks away a handful of route species. Ekans, Oddish, Mankey, and Growlithe stay in Red, while Sandshrew, Bellsprout, Meowth, and Vulpix belong to Blue, with Scyther and Pinsir split the same way. Trading with the other version is the only way to fill those gaps.
Three rods, three givers. A fisherman in Vermilion City hands over the Old Rod, which only ever hooks Magikarp. The Good Rod comes from a fishing fan in Fuchsia City and adds Poliwag, Goldeen, and other common catches. The Super Rod, waiting on Route 12, reaches the rod-only rarities listed here.
