I'll ride my Fargo-29incher. One loop would be great, North from Whitefish to Red Meadow Lake campground, then over to Polebridge, South on North Fork Road-that's what shows up on google maps (It's actually Outside North Fork). halfway down toward Columbia Falls there's a campground right off the road, but---it's heavily traveled, with everything from private cars to semi-tractors, and dusty in Summer. Inside North Fork has not been passable by automobiles in a few years. still OK for mountain bikes though. It has several campgrounds on it, and is used by backcountry travelers, but I don't know the condition of the campgrounds if they haven't been serviced. That road will require crossing washouts and some downed trees I'm sure. If we can handle the dust for about 25 miles on North Fork road, the opportunity presents itself for a fully supported tour with us not hauling anything. If we cross the river at Polebridge, and travel down the Inside North Fork, we'll have to lug our stuff, but what if we split that with a support vehicle that would meet us at Fish Creek Campground? It's about 27 miles from Polebridge to Fish Creek campground. we could do that in a day, or we could split it up and camp one night there. We'd certainly haul less on our bikes that way. Inside North Fork ends right at Fish Creek Campground, too! I'm attaching a video of 4 people who did this from Whitefish. I'm certain that they took the Red Meadow/Polebridge/Inside North Fork loop, rented the B.O.B trailers in Whitefish, probably from Glacier Cyclery. At one point, they're camped at Logging Creek Campground, and that's on the Inside Road. There's some hills on the road, but it's pretty much all gravel/dirt except around Whitefish and Columbia Falls.
