Thunder Mountain is considered a marquee/classic/bucket list type trail in many publications. I have to say it lives up to hype. This video is from Day 15 of the Summer MTB vacation which was our second crack at this trail. We got rained out for this ride on Day 13. We managed to catch a good weather window and for the most part we were rewarded some near hero dirt. But be warned, even if you “shuttle” it you will be spending plenty of time cranking the pedals. It is well worth every bit of grunting you have to do.
