On Route 217 (the snowy route heading to Snowpoint City), there are two houses. In the first house, a hiker will give you an Icicle Plate if you give him the HM 08: Rock Climb from behind his house. In the second house there is a lady that will give you a Spell Tag. Enter the second house and talk to the lady to get a Spell Tag, then go outside and enter the house again. The woman will have disappeared.
