We took Beach ave. which is also County Rd. 164 south out of Pine Bluffs, Wyoming for 12.1 miles to the sign for the Tri-State Marker. From there you’ll need to walk to the actual marker. Be careful and stay on designated trail because it is private property on both sides. We were lucky enough to meet Marty that was checking on the property and livestock there and he gave us a ride in a side by side to the actual marker which is 0.73 miles out from the parking area, so it’s 1.46 miles roundtrip.
