  • Take the path going down on the right of the church for approximately 100m.
  • Turn on your left when you find a pedestrian path going down.
  • Go down until you cross a small river on a bridge (after the 2nd roundabout).
  • Just after the bridge, follow the path until you have building 210 on your right.
