There are a few other adventures to be had up there. As others mentioned you could get a float plane to fly you from the end of the TT to near Churchill and combine it for a great loop of Quebec. Also there is a LONG hydro line that connects the TT to the North road. When you get up there its on the Hydro maps and no others. We were intrigued but it would be a big undertaking and we weren't prepared or have the time for it this time around. A local said it is very rough and a bridge or two may be washed out. Dont think we weren't tempted, we'll leave that one for someone else. My guess is its about 300 to 400 km long, hasn't been travelled in a few years and probably never by bike. Your gonna have to be creative for some river crossing. Good luck, let me know when it gets done, I look forward to reading the ride report.
