Proceed down highway 313. Once entering the park proceed to Grand View Point. At Grand View Point take a right and walk the rim about 1/4 of a mile for this breathtaking spot.
Winter is a great time to go however dress warm and be prepared for some relentless cold wind.
This shot was taken at sunset near Grand View Point Overlook. I find when photographing canyons it's especially hard to show just how vast they are. For this shot I placed the subject on a ledge to show the vastness of the canyon as well as how steep the cliff ledges are.
