The president's Grand Canyon visit on Sunday was a private affair with no public events. He plans a speech at the annual Veterans of Foreign Wars convention in Phoenix on Monday.
Obama's motorcade passed by a large crowd of waving tourists who lined the roadway west of the park's main South Rim lodge area at midday. The family then toured an area known as Hermit Road, which has various lookout points, a rest area and a rocky but popular trail meant for experienced hikers.
The Obamas spent less than four hours at the scenic wonder carved out by the Colorado River.
The president arrived in Arizona on Saturday evening on the last leg of a swing through western states that included visits to national parks and town hall meetings.
