Proceed straight onto Hwy 78 at the intersection east of the Safeway.
There is a Shell station on the right.
It is a little confusing because to stay on Hwy 20 like you were continuing to Ontario you have to turn left or north at that intersection.
Going straight or staying in direction you have been traveling puts you on a different highway, highway 78.
Anyway about 92 miles on Hwy 78 past Burns you reach the hamlet of Burns Junction where 78 intersects with Hwy 95.
South or to the right on Hwy 95, 21 miles.
There really is not much chance of missing Whitehorse Ranch Lane off 95.
After you pass the Stoddard place about 10 miles south of Burns Junction on the west or right side of the highway, all you see is our Coyote Lake allotment on the right until you get to Whitehorse Ranch Lane.
The sign is not large but it is a 30' county road and there is nothing to confuse it with.
In the unlikely event that you pass Whitehorse Ranch Lane and end up in McDermit, Nevada, you went too far.
Once on Whitehorse Ranch Lane there really is nothing to get confused with because 22 miles on we are the only ranch you will see.
There is a driveway on the left or south side of the road leading to 12 Mile Ranch (cleverly about 12 miles off 95) but you will not see the ranch and there is no sign.
Another 10 miles down the road on the right is the driveway to Whitehorse Ranch. It is pretty obvious with the houses, trees, fences, signs, and other stuff.
At night you can see the ranch about 14 miles out like a mirage in the distance.

If you want different scenery you can take the Denio/Fields highway off 78, about 64 miles east of Burns. You will see it on your right.
There is a sign that says something about Fields and Denio that way.
This is your opportunity to travel on the west side of the Alvord Desert, by the famous hot springs, past Andrews, and get to see the east (rain shadow) side of the Steens Mountains.
Once in Fields remember this is the last chance for a while to have a milk shake.
Conveniently south of Fields about 15 miles is the other end of Whitehorse Ranch Lane.
It is a bog Y intersection and because the sign is in the middle of the Y is is very easy to pass the northern branch of the Y.
The southern branch of the Y works just fine an a left turn there will get you back on track.
Continue east on Whitehorse Ranch Lane will take you to Whitehorse Ranch in 24 miles.

If you have not visited the Peter French Round Barn near Diamond you can take that cutoff at New Princeton, south of Crane.
That road will take you by the Malheur Refuge and intersect with Hwy 205.
Left on Hwy 205, 65.5 miles will take you to Fields.
On this route you get to pass through and hopefully stop at the Frenchglen Hotel, pass through the Roaring Springs Ranch and experience the Pueblo Summit.
If you are towing and it is snowing and you do not have traction tires or 4-wheel drive your experience on the Pueblo Summit may last a little longer than you might have intended.
Once in Fields the directions above will apply.

Of course you could take 205 south out of Burns (south or right at the Shell station east of the Safeway) still go trough Frenchglen and the Roaring Springs Ranch, climb the Pueblo Summit and end up in Fields in 106.4 miles that way.

If you are pulling a trailer or driving at night, any of the routes will work but the first one is easiest, unless it is March, you don't have 4-wheel drive, and has been raining recently.
In that case the 12 mile hill off 95 can get a little slick and approaching Whitehorse Ranch from the west may be best.
If not pulling a trailer it really does not matter which way you travel.
