Pokemon FireRed and LeafGreen Route 1, Viridian City, and Route 22 Walkthrough
Route 1, Viridian City, and Route 22 section for the FireRed and LeafGreen walkthrough with source-backed wild Pokemon, trainers, items, hidden items, bosses, and route notes.
Make the parcel loop, buy early supplies, catch Route 1 support, and optionally fight the early Route 22 Rival before the Pokemon League gate. This page is a standalone section for Phase 1: Boulder Badge, with FireRed/LeafGreen source data for encounters, trainers, items, hidden items, and boss routing.
Source maps
Route 1, Viridian City, Viridian City House, Viridian City School, Viridian City Pokemon Center 1F, Viridian City Mart, Route 22, and Route 22 North Entrance.
Route plan
Fight the early Rival if you want extra EXP before Viridian Forest; skip if your starter is fragile and you would rather train first.
Route Notes
- The old man catching tutorial unlocks normal northbound progress after the parcel delivery.
Wild Pokemon
Each area below has its own table, split by encounter method. Standard wild rows merge every slot for a species into one line with a combined rate, and FireRed/LeafGreen exclusives are marked with FR/LG game chips; there is no time-of-day split in these remakes. Underlying slot odds: grass and cave 20/20/10/10/10/10/5/5/4/4/1/1; Surf and Rock Smash 60/30/5/4/1; Old Rod 70/30; Good Rod 60/20/20; Super Rod 40/40/15/4/1. Gift, static, trade, and prize Pokemon keep their own labeled rows.
