We went there in the early morning to be there before the tourist Bus crowds arrived.
Arriving early morning allowed us to beat out the hottest part of the day. Do still plan for the 15 minute walk from the parking lot to the viewpoint Rim to be hot and unshaded (it was 90 degrees).
Since it was morning, for photo purposes the Bend and surroundings are partially in the Sun and partially in the Shade.
I do hope the US Dept of Interior would place trash containers near the Rim since littering is an issue there.
For a less crowded viewpoint, walk to the far right where it is more peaceful.
