I was recently able to scratch the Grand Canyon River Trip off my bucket list. I went with a photo tour rather than a regular commercial trip as the photo tour would have us in the right locations at the best time with best light for photography. We had clouds, sun, rain, blue waters, colorful sunsets, canyon glow, dappled light, reflections, waterfalls, and good food. Here is a selection of favorite images, but there is a plethora more on the website.
