Coal Canyon is officially located in Chino Hills State Park; however if accessed from Green River Golf Course area in Corona then the trail will be found from following the bike trail path after a mile or so. On the left is the underpass which leads to two main pathways.

After the bike trail, you'll make a left. Go straight up the middle and you'll eventually find the trail. Once you find the stream, follow the stream all the way to the end.
Pay attention on your way back. if you follow the stream back, you'll end up off the trail. There's a little stream waterfall at the end. Right before it there's some shade. Quite relaxing for a little break.

there's a little waterfall at the end of this trail. probably a rare sight that only happens after the rains we've been getting. very rocky trail, stream from waterfall is going right through the middle of the trail. bring waterproof shoes.

The recent fires destroyed most of what must have been a beautiful place, but there is life coming back to the area.

I did this hike yesterday.
I enjoyed it. A good amount of incline actually, so I would rate it more on the moderate side. I went on a afternoon hike, so the sunset looked pretty great. I suggest people park at the entrance of the golf course on green river rd. You will see parking spaces and a bike path will be very visible when you park. You have to walk the bike path to get to the trail. It's about a 15 to 20 minute walk on the bike path. You will come to a point where there's a mining/drilling type of tractor and u will see the freeway bridge to your left. Walk under it and you will finally see the sign saying coal canyon trail. Enjoy!

definitely multiple ways to get up, used Google maps along with this app to guide my way to the radio towers and explore the abandoned star ranch saloon.

I had to visit this trail twice just to find the right one that went to the waterfall. As long as you keep to the left after going under the freeway and follow the"Big Mo Tail"you'll be fine. I Just hate walking that paved road back to our cars. It's tough on the feet.

This was a good hike but I never did see a waterfall. Where is that at? Felt like we were walking uphill forever. We walked under the freeway off the bike track and took the dirt trail on the left. Does anyone know where we should of gone to see the waterfall? Hit me up please and let me know cause I would like to go back. crystal_newhouse@Yahoo.com

Only made it half way to the towers gonna go all the way next week, was kinda confused couldn't see the towers not one time during the hike found out we were almost there. It's up up up !!!

Great easy hike. The waterfall was flowing pretty good! The trail is a bit washed out and muddy in some areas from the recent storms.

Monday, January 16, 2017

park at the golf course at green river. take the bike path for about a mile. you will see a point where you either continue on bike path or go left under freeway. go left, go under and you will see sign for chino hills state park. that it the entrance. then look for sign that says big no trail. keep going. it's about 2 miles or so till you get to the point the waterfall would be. we went, a couple days after the storms and no water fall just a trickle. BUT we would totally go back after the rain. this is an easy hike and it beautiful! #kidfriendly #plussizefriendly

Off the 91, head north on Green River Rd and park just past the golf course entrance. There is a water fountain there to fill up your bottles. From there, walk down the incline to the start of the new bike path (through the gate) which runs parallel to the Santa Ana River. Ignore the first underpass (private road entrance) and continue walking for about 15-20 minutes. After a short incline and bend, you will come to an information kiosk on the right with the underpass leading to the trails to the left.

Because of the complete absence of signage and construction activity it is easy to get confused and not even find the trailhead.

if this is your 1st time, READ THIS! park at the golf course entrance where the bikers park. go left on the bike trail for about 1/2 mile. you will see a an opening under the freeway in the left. on tje right you will see a little bench shadded area with some wildlife info. that how you will know you are ready to leave the Santa Ana Bike Trail. once under the bridge you will see a trail head named Chink Hills State Park. almost immediatly there is a fork in the road. we went to the right/straight which was bery tough! all uphill with hardly any shaded areas! ive read that id you go left at the trail it may be easier. will be teying that side on a later date!

got confused once i hit the sign for coal canyon...i did make it to "Big Mo Trail" which i am almost positive this is the same exact trail as my GPS shows i followed the same path indicated here.......its an out and back of pretty gravely terrain and a steady mild climb to the top, probably an old rain wash path or creek bed..... awesome ride for a fat bike or niner with low gearing, its a straight shot out to the ecological boundary then a straight (mostly downhill) return the exact way you came...pretty hard to get lost but always be cautious and use common sense.... its isolated, dry, and the terrain is a little on the rough side but the solitude is enjoyable and so close to home!

A little difficult to find if you don't know the area. The road to the trail is actually closed for construction, but there is parking just before the entrance to the golf course and you can walk on the bike path to the bridge under the 91 to the trailhead. The creekbed is indeed rocky, and the fire road up the hills is fairly steep and a constant incline. The views are fantastic and there was no other people when I was there on a Saturday afternoon. It was a good workout, and worth the walk on the bike path to enjoy a beautiful sunset in total solitude.

A little rocky through the dry riverbed but still a nice little hike to the end.

Beautiful cool day with soft rain and intermittent sunshine… Once the 91 freeway is out of sight this becomes a very beautiful hike. Take the route that says MO trail along the dry Creek. There's no water in the creek most of the yearl which just means that you'll be able to hike all the way to the dry waterfall. The walk is a geologist's dream with sub-bituminous or possibly lignite coal, gypsum and classic stratification on the way to the end. There's also a tremendous amount of plant life; a variety of succulents and brush that yields berries and some kind of yellow fruit that looks like a tennis ball but is as hard as a rock. The trail peters out long before the waterfall, But keep going up the creek to the end of a very narrow slot canyon. Nice little hike.

Great and easy trail.. Still very accessible. Waterfall was just a trickle but if El Niño ever shows up I'm sure it's a great sight to see

Trail is inaccessible

I hiked the route Chris Leschke uploaded going to Lookout Rocks, but I made the trip coming from the Gypsum Canyon side. Easy parking, and you start out walking along the Santa Ana River Bike Trail to get to the underpass and the real trailhead. Once you've trudged up the steep road and gained the first saddle atop the ridge, it's nice and quiet, and the views just keep getting better as you climb. This is a great hike for spring, or anytime the weather is not too hot, and you get a rare close-up look at Tecate Cypress, which grows along a stretch of the trail about a mile or so before you get to the summit, and Lookout Rocks. I'll be in the area again soon, so I think I'll check out the waterfall trail this time (not that there would be much water this time of year, but I bet it won't be as steep!)

No access to coal Canyon only riverbed trail next to the freeway. Too bad I guess it used to be a good hike into the canyon but I heard there was an accident that put a stop to all that hiking back into the coal Canyon not allowed to go cross the railroad tracks that block it.

Came here after Thanksgiving to walk off the turkey, didn't see a single soul for the entirety of the hike which was awesome. Check out my write-up at http://travel.suwdo.com/2014/11/after-thanksgiving-hike-on-coal-canyon-trail/ complete with photos, map, and elevation profile.

Great hike with awesome scenery.

Beautiful, moderate hike. Definitely a must do hike in the area. It's hard to find hikes in the Riverside area, I would recommend this one, for sure. Another plus: it's quiet! For the most part, it's not too crowded! Easy parking too!

After you get to the trail head, by way of the Santa Ana River bike trail, this is a really cool outing. There are loads of different tracks and access roads in the back country that can take you to quite a few different places. We went up to Sierra Peak on this occasion, but the whole area is pretty fun to explore. The trail doesn't get very heavy use either and it's kind of peaceful not having to deal with tons of people.

Nice hike. Didn't see anyone else the entire hike. With the drought very, very little water at the fall. Still enjoyed the peace and quiet. Look out for poison oak at the top near the falls.

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.)

I work a couple exits from this place and have been looking forward to checking it out for awhile. With decent rains yesterday, a short day at work, and some friends available to go with me, we set off! The hike on the bike trail felt like it went on forever (even more so on the way out), but we got to see some awesome machinery the men below were using. Once on the path SOMEONE READ THE MAP WRONG, and we ended up going 1/5 of the way on the Coal Canyon trail. We made a fun exercise out of it though and jogged the whole way down. Once on the right (Big Mo) trail, the directions seemed to make more sense, and we were there in no time. This place is gorgeous, but there was very little water. It was still a breathtaking surprising. The grotto was stunning. The weather was perfect with a nice, cool breeze, and the views were out of this world! We could see the mountains in the distance, smothered in snow. Definitely plan on checking this place out more often, and hopefully have more time before the sunsets to explore!

Waste of time. We wasted a whole day trying to get into this trail. Finally on the third try we were able to access the Chino State "Park" from Brea only to find out that dogs are "not" allowed (ALLTRAILS says otherwise). Won't be back and questioning this site now as well.
