If you are going to go all the way to the North Rim of the Grand Canyon to camp and ride the Rainbow Rim trail, it is well worth it to add a segment or two of the Arizona Trail that runs through the area into the mix. This is from an 18 mile snippet of the trail south of Jacob Lake. We did this on Day 11 of August MTB Vacation.
Getting out to the North Rim of the Grand Canyon to ride the Rainbow Rim trail is not an easy feat. For just about everyone it will be a camping trip. This is from my August MTB vacation were we camped on Locust Point for a handful of days and enjoyed the views and the riding on this trails as well a bit of the Arizona Trail. The video really does not do the experience justice. You need to get there to enjoy it for yourself.
I had to put the videos on hold while I went down the rabbit hole of squaring away data storage and backup system. I came back from the August trip with just about a terabyte of video and photos which put my overall storage at near capacity. I now have a more robust system that should scale a lot better in the future.
