If you’re looking for an amazing hike in the Inland Empire, you have to check out Sapphire Falls. Located in Rancho Cucamonga, Sapphire Falls makes a great day hike alone or with a friend.
This trail used to be 100% open. Due to the massive amount of vandalism and other issues, the private property owners have signed No Trespassing orders and asked the City to enforce No Trespassing laws.
Here are some directions taken from the Rancho Cucamonga website:
If you are visiting Cucamonga Canyon you will most likely enter through the City of Rancho Cucamonga. The only legal way to enter or leave the canyon is on Skyline Road. Skyline Road is located at the top of Sapphire Road and runs north from Almond Street. All of the land to the west of Skyline Road and south of the second forestry gate (including the wash) is private property. If you utilize private property to enter or exit the canyon, you are subject to arrest or citation for trespassing. The police department is working in the canyon every weekend to enforce all laws.
Remember; if you leave the main trail you must have a way to get back. Many of the routes to Sapphire Falls are easy to get down, but nearly impossible to get back up.
Sapphire Falls trailhead is located at 8043 Almond St, Rancho Cucamonga, CA 91701.
