Santa Ana Canyon

Santa Ana Canyon (or the Santa Ana Narrows) is the water gap where the Santa Ana River passes between the Santa Ana Mountains and the Chino Hills, near the intersection of Orange, Riverside, and San Bernardino Counties. It receives particularly strong Santa Ana winds in comparison to surrounding areas, hence the name.

Originally, U.S. Route 91 ran through the canyon; however, it has long since been re-signed or upgraded along the entirety of its former right-of-way in the state. California State Route 91 - known as "the 91" - is its primary successor.

The Santa Ana River bicycle path runs through the canyon. This recreational path was constructed on the bank of the river and abuts the length of Yorba Regional Park in Anaheim. The bike trail, as it is referred to by locals, roughly parallels the 91 in certain areas, extending all the way to PCH on the coast of the Pacific Ocean. Across SR-1, Santa Ana River County Beach awaits, which shares a border with Huntington State Beach.
