Annie Falls is a waterfall on Annie Creek in Crater Lake National Park in southern Oregon, at the south end of the Rim Village Historic District. It is the tallest of three waterfalls of the same name along the creek and drops within a steep canyon shaped by the landscape around Mount Mazama. The canyon’s walls of petrified volcanic ash are remnants of the eruption that created Crater Lake. Because the falls lie deep in Annie Creek canyon, they are difficult to reach directly, though partial views are available from a nearby picnic area and the U.S. Forest Service snow park provides access to the creek. Both are known for high water flow.
