To get here exit the 91 freeway at Green River Road. Take Green river road towards the Green River Golf course, Park at a big dirt pullout on your right. Now start west toward the golf course. You will see the paved Santa Ana River tail heading west take that. Cross the bridge over the Santa Ana River and follow the paved trail until you see the underpass for the 91 Freeway. From here head south under the freeway overpass to the Chino Hills State Park Sign. From the Sign continue on the only path south. stay on the trail/Road south. Then after a while you will come to the State Park Boundary. Now drop down to the right into the dry creek. Continue up the canyon avoiding all side forks. Soon you will approach the narrows where the falls are located. Spring/Summer/Fall watch out for rattlesnakes!!!!!

easy enough trail for mtb-ing makes for a fun little warm up before taking the much harder coal canyon fire trail to the right.
fyi,for those who cant find the trail or have posted their ride on the golf course side of the 91 you're on the wrong side. if your at the green river bike trail go west go under freeway left at coal canyon, go through gate and follow trail. if you take the fire road you are on the wrong trail.

This is a nice little hike up the middle of Coal Canyon. The final half of this hike is basically trekking up a mostly dry stream bed. We went immediately after a pretty heavy rain storm so towards the back of the canyon, the falls were actually running, but we noticed there was significantly diminished water flow by the time we left, so if you do this hike to see the falls, be sure to go right after it rains. The Canyon itself was surprisingly quiet and peaceful, especially so when you consider it's proximity to a major freeway.

A small, hidden, box canyon waterfall right off the side of the 91 freeeway at the “Offramp to Nowhere” in Coal Canyon. (Date hiked: April 2, 2011 and April 26, 2009.) Read the full write-up at:

Headed up this way after work. Have not been into this area before so I took the mountain bike up the road into the canyon proper (as there are 3 options: a road leading up to a ridge on the west rim of the canyon, a road leading up the east side of the canyon and the road down the center of the canyon) and ended up at the reserve boundary marker. From here, I carried the bike a few hundred yards up the creek and stashed it. From here I headed up hiking up the dry creek bed and took off up a side canyon to a small cliff. After bushwacking up the side canyon I decided it was time to go, so havent made it up to the narrows yet. Definitely a cool area that warrants a bit more exploring. I think I'll wait a few months as I imagine it would be quite a bit more interesting with some water.
