We have had several trips to the USA and have seen the good, the bad & the ugly.
Top of my list for special places is the Grand Canyon and the other canyons which make up Canyonlands National Park. It is truly a spectacular place.
My impression of the Grand Canyon is best summed up by this expression..
“There is of course , no sense at all in trying to describe the Grand Canyon. Those who have not seen it will not believe any possible description. Those who have seen it know that it cannot be described. In fact, the Grand Canyon is a sort of landscape Day of Judgment. It is not a show place, a beauty but a revelation. The Colorado River made it, but you feel when you are there that God gave the Colorado River its instructions.” J Priestly 1930
We stayed overnight at the Canyon which meant we were able to sit and watch the sun set over the Canyon thus creating a myriad of colours. It truly is a spectacular place.
