Walkthrough

Advance the objective. Follow the section summary and finish required rival, Plasma, Gym, or League battles first.
Sweep trainers and items. Use the tables below in map order, then make a separate Dowsing Machine pass.
Set the right filters. Black 2 and White 2 diverge in encounter slots, routes, facilities, and key unlocks; difficulty modes keep distinct boss records.
Close optional loops. Check Hidden Grottoes, weekday statics, seasonal access, gifts, and postgame prerequisites before leaving.

Pokémon locations

Each area below has its own table, split by encounter method. Rates merge every slot for a species and are shown per season; a single centered rate means all four seasons match. Time of day never changes Black 2/White 2 wild slots. Identical Black 2 and White 2 slots share one row with both game markers.
