Long Roadless Trails ?

Trail around Three Sisters in Oregon is maybe 47 miles – PCT on the West side, Green Lake trail on the East side

Lots of PCT sections in Washington, like South of White Pass through the Goat Rocks

Lots of trails in the Olympics – I bet you could find a 100 mile loop

The Wallowas in Northeast Oregon

The High Sierra trail across SEKI to Whitney is ~70 miles with no roads. One of my all-time favorite trips.

What about the Bob?

Check out the Pasayten Wilderness in north Washington.

"I'm looking for long, high, roadless (and ATV-less) trails, greater than 50 miles."

1) The High Sierra Trail to the Kern Canyon Trail to the John Muir connector trail to the JMT to Roads End in KCNP.

1) Mineral King to the Kern Canyon Trail over Franklin Pass and down Rattlesnake Creek. From there to Lake South America and then use two short connecting trails (see Mt Whitney 15' map) to the JMT and head north to Roads End in KCNP. This route will take you through the heart of the Kern River/Upper Kern Basin, which is some of the mos magnificent country in the Sierra. Lots of opportunities for beautiful one/two day side trips(Milestone Basin, Thunder Basin). Well over 50 miles. It could be done in 5-6 days if you wanted to push it, but I'd recommend 8-9 days to leave time for really enjoying the experience. There are also a couple of neat variations that involve off trail travel. PM me if interested.

Tom,
I have a couple of your routes bookmarked.

This is indeed a great area amenable to building long loops.

Thanks.

"This is indeed a great area amenable to building long loops."

Very much so, Greg. Somehow I overlooked the possibility that you might want to do a loop. If you have gone as far as bookmarking the routes and have the relevant maps, you'll have an easy time coming up with a number of loops. You really can't go wrong down there. It is my favorite part of the Sierra, hands down. You'll have a great time if you end up going there. Let me know if you need any info that isn't in the books or online; I know the area pretty well.

I was trying to figure out a place for a next Sierra hike, that sounds like a real winner.

Canada, you can go hundreds of KM on trails with no roads/ATV tracks in the parks up here. with no people on them. And u don't need a bear canister.

You might look into the Frank Church Wilderness in Idaho.

Anytime, Dirk.

Tom's suggestion is similar to the route that I plotted out for myself for this summer. One variation is to go north past Lake South America and over Harrison Pass to East Lake to Bubbs Creek. The major problem is one of transportation back to Mineral King. Kaweah Gap, Colby Pass, and all of the rest of the high spots in that vicinity have fabulous views.

Since you are in Colorado, how about a traverse of the Weminuche wilderness. Probably 110+ miles from Wolf Creek Pass to Vallecito Creek TH near Durango. You can add on another 80 miles or so if you start at Cumbres pass and do the CDT through the S. San Juan Wilderness first. Then you would have to cross US160 @ wolf creek, but you could just close your eyes and run, and your back in the wilderness. Also the Gila wilderness in NM could swallow a 2-week trip with no road crossings if planned correctly.
