The Nahanni Range Road heads east from the Robert Campbell Highway to Tungsten, Northwest Territories. It is 200 km (125 mi) long with no services. Enough fuel for at least 400 km (250 mi) is required to drive the whole road. As well, the Nahanni RR turnoff is 100 km (60 mi) north of the nearest fuel stop in Watson Lake YT. This means, travelers must have enough fuel for at least 600 km (370 mi). We carried an extra 10 gallons of diesel.
If the tungsten mine at the end of the road is open (which it was in 2007) the road will be maintained. Stay alert for one or two semi-trucks a day barrelling along the middle of the road. The trucks go in and out on the same day. I am sure they did not expect to see tourists meandering along towing a little fifth wheel trailer.
It took us a day to drive in, but we were meandering along enjoying the views. Despite diligent efforts looking for wildlife, we saw very little.
For additional information about the Nahanni Range Road (external links):
The government campground at Simpson Lake (km 81 on the Campbell Hwy) was a pleasant beginning to our day. The start of the Nahanni Range Road was just 25 km north of the campground.

Information sign at the start of the Nahanni Range Road
This sign, at the start of the road, turned out to be an accurate sign, other than for the typo.

Today, blue skies and good gravel road greeted the truck ...
Clear blue skies can be amazing in the north in the autumn. We were thrilled to see the unending blue horizon.

Nahanni Range Road
The first 80 km provided reasonable road conditions and nice scenery.
We didn't know yet that the best was another 50 km ahead.

Nahanni Range Yukon gov't campground sign, km 84
The campground was in the middle of a large
forest fire that burned about five years ago.
Even so, it would have been a good
overnight spot.

Hyland River from the Nahanni Range campground
It was only midday though, so we carried on after lunch.

Hyland River where it intersects the road at km 110 (mile 68)
This warning at km 134 should be taken seriously ...

Warning sign alongside the road
We carried on past the sign ... we understood the risk of traveling on remote roads and were prepared to take care of ourselves for an extended period if necessary.
Further along the road, the blue skies and clear day provided perfect picture opportunities ...

Overall, the road was in good condition. This area had been freshly graded ...

View looking west as we head towards the Northwest Territories
After leaving the valley floor, the road climbed towards the Northwest Territories.

Looking back at the Yukon
The road was narrow as it climbed. On one side of us was a wall and on the other side was a severe drop with no roadside barrier.

Small lake near the highest point along the pass
We wondered where the border between Yukon and Northwest Territories would be. A "Notice to Hunters" was the only marking.

Sign marking the boundary between Yukon and NWT
The sign below gave several warnings:
downhill (graphic), DEADEND AHEAD
300-400 FT, and KEEP RIGHT.
We were not sure what was ahead so inched along. We had little choice, as there was no place to turn around with a fifth wheel behind us.
Turns out the sign should have said "90 degree left turn and if you don't make the turn you're going to drop over a vertical bank that drops a long way".

I took video of this experience, so wasn't able to take a picture. There was a checkerboard sign as we approached the corner, visible in this 36-second video. Apologies for the low-res video ... I was using my small Canon digital and it is best for still shots.
Continuing along, the scenery was spectacular ...

Looking towards the Northwest Territories and the Ragged
Mountains
We drove to the end of the road at the tungsten mine.
There isn't much to see from the end of the road ...

End of the road at Tungsten
We heeded the "No Trespass" signs and turned back.
A few kilometres of backtracking and we found a fine spot to set up camp.
If you look again at the fourth picture up, you'll recognize the spectacular
backdrop of the Ragged Mountains ...

Boondock site alongside the Nahanni Range Road, near Tungsten
The evening was very quiet, with a few planes flying overhead. A couple of workers from the mine came along, on their way to retrieve a moose they shot the night before. They told us the planes were flying between Tungsten and Macmillan Pass, where there was another mine (end of the North Canol Rd). They also told us not to wander too far without reflective gear as some hunters liked to shoot into this valley from the road above (the road we drove in on), and they thought some of the hunters wouldn't expect to see two humans and a dog out for an evening stroll and might assume we were something else in the dusk. So they thought it best we be brightly decorated.
We didn't meet anyone else that night; nor were we used for target practice.
