The South Rim of The Grand Canyon is more popular then The North. It has the picturesque views you think of when you hear "Grand Canyon" and it's really breath taking. In 2009, we took a side trip to The Grand Canyon while out in Las Vegas for the Nellis Air Force Base Air Show. I mark this trip as the beginning of my obsession with the National Parks.
After being to both rims of the Grand Canyon, the last part is to see it from the bottom up. In August 2015, we took a 3 day rafting trip that covered about 100 miles of the Colorado River ending at Lake Mead.
The North Rim of the Grand Canyon is the lesser traveled to part. Partly because its so much further away, and partly because it's not as tourist friendly. But the views up there are just as breathtaking.
