Etiwanda Falls is a waterfall in the North Etiwanda Preserve in Rancho Cucamonga, California, fed by East Etiwanda Creek and reached through a short hike of about 1.6 miles into the canyon. About 50 feet high in total, it was formed where two streams joined and concentrated their flow into a single channel. Instead of dropping in one continuous plunge, the waterfall descends in three separate tiers measuring roughly 15 feet, 10 feet, and 25 feet, giving the falls their distinctive stepped character.
