Just after leaving highway 73, you will see this information board. Take the road to the right where the truck is at. The one straight ahead will take you to some places where you can camp but the road to the right is the one that will best take you to the Topliff Hill area. There is a small highway sign that says SP 10. Watch for that. If you overshoot this turnoff, turn left on the pony express road and take the first connector on the left to the Railroad Bed road.
