Source maps
Digletts Cave, Route 2, Route 2 Trade House, Route 2 Gate, Route 11, and Route 11 Gate 2F.
Route plan
Diglett's Cave is the Surge answer and the route back to Route 2's aide. Route 11 builds levels for Rock Tunnel.
Wild Pokemon
Each area below has its own table, split into encounter method bands: tall grass / cave floor, Surfing, the three rods, then gift, trade, prize, and static rows. Grass and Surf rows merge every Gen I wild slot for a species and show the combined odds out of 256 (slot rates 51/256, 51/256, 39/256, 25/256, 25/256, 25/256, 13/256, 13/256, 11/256, and 3/256). Generation I has no time-of-day split, so no rate varies with the clock; a — note means the row needs nothing beyond reaching the area.
