Adobe Falls, Seasonal waterfall in San Diego, United States

Adobe Falls is a seasonal waterfall in San Diego that flows down Alvarado Creek in several steps, creating a series of rock drops. The waterfall is located in a suburban area and shows different water flows across its various sections.

The waterfall was recognized as Historic Landmark number 80 by the San Diego Historical Resources Board in 1973. This designation acknowledged its geological and natural importance to the region.

The rocks surrounding Adobe Falls are covered with spray paint art created by local people, showing the blend of nature and community expression near San Diego State University.

There is no legal public access: the land is owned and managed by San Diego State University, and signs, fences and regular patrols mark the site as closed. The waterfall is seasonal, so the flow varies with rainfall and the channel can be dry. Do not plan a visit around reaching the falls.

The falls are a seasonal cascade on a tributary of the San Diego River, so the flow depends on rainfall rather than a year-round source. San Diego State University owns and manages the land around them.
