There are many wonderful programs, exhibits, and events presented by the National Park Service (NPS) and Grand Canyon Association (GCA) at Grand Canyon, as well as lectures offered by GCA at various locations throughout the state on Grand Canyon and Colorado Plateau subjects. I have included these in the calendar below.
For more details on any event, click on it. Some events have even more details (and maps) linked within the description.
To minimize the number of items displayed on the calendar, you may simply click on the "down" arrow next to the Agenda tab and "uncheck" the events you wish to remove from view. Since they can impact scheduling, I included U.S. holidays in the calendar as well. The default view is is "Agenda" but you may easily change it to "Month" or "Week" by selecting the desired tab.
