Use Helsinki Outlet shopping center parking lot. Head to the forest from the southeast corner of the parking lot.
If you come by bike, you can enter the forest from the southside. A cycle track comes there from Vaarala and Heikinlaakso. Follow the track in the forest that starts near the Lahri motorway cycle track bridge. From Vaarala or Heikinlaakso, you'll find Karkkitori first. Outlet-Murikka is closet to the parking lot, with Laikujäkälä on the other side of the hill.
