Pokemon Heart Gold and Soul Silver - Walkthrough - Route 29 Pokemon Heart Gold and Soul Silver: Walkthrough - Route 29
You can encounter Pokemon throughout this Route. Make your way west through the route, it is a pretty linear path.

Head down and west, through the Tall Grass. It is a good idea to get some training done for your Pokemon, but you can take short routes through the Tall Grass if you just want to get through quickly.

When you reach a point where there is an opening in the ledges (with the boy on the left side who tells you about Tall Grass), go north, then east and north again through the L shaped tall grass.

There should be a Gatehouse to the north, but just keep going west for now.

There is a boy on a ledge with an APRICORN TREE, but you cannot obtain any right now as you do not have proper methods to carry it; so, jump off the ledge going down, and follow the road to the west.

You will enter CHERRYGROVE CITY.
