Route 15

From Black City / White Forest Route 15 leads westwards up some stairs, then across a bridge to the Poké Transfer Lab. Past the Poké Transfer Lab there is another bridge and more stairs heading south. West of these stairs there is a trailer where Lillian will offer to trade her Rotom for a Ditto. Alternatively, players can head down some stairs south of the eastern gate and through tall grass. There are two Strength boulders in this route, the southeastern one leads to an item while the northern one leads to dark grass and another item. Continuing east past the Strength boulders there is more tall grass and a narrow path up some stairs leading to a hidden item. There are three ledges in the western half of this route.
