My experience with this route is excellent. Going up and back is approx. 30 miles. The trailhead is at 4995 Green River Rd., Corona. It has ample parking. I hit the path going south with the river to my right and the 91 fwy to my left. Once I get to the first park, Featherly Regional Park, you end up looping so that the river is now on your left and riding alongside E. La Palma Ave. for a couple of miles.

Shortly after you cross Yorba Linda Blvd. going south, you're now led to the dedicated bike path for the remainder of the ride and much closer to the river. The riding surface is in very good condition. Yorba Linda Regional Park is on your right. It's a long beautiful park. You may want to stop and explore it. Right after the park ends you cross a bridge with a wooden surface and now have the river on your right. You're now at approx. mile 5.

As you proceed south, you go under several overpasses and there are some nice wide curvy sections with beautiful vegetation on both sides. At approx. 12 miles there's a mini park rest area with benches and water fountain on your right. It's a nice place to stop and have a snack for a few minutes.

It starts to gets more barren as you go further south. Looking ahead you can now see the Honda Center, Anaheim transportation center, and Anaheim Stadium a few miles away. When I get there its mile 15 and I turn back.

As I end, I do want to say that it's best to check out the weather forecast mainly for wind. There have been a couple of times when I had to turn back because of strong winds! I recommend you start in the morning around 7-9 am. From the trailhead at Green River to the Honda Center it's mainly going downhill. So, just keep in mind that you'll be returning going uphill. But it is a moderate climb. During my rides I did not see any homeless encampments. If you prefer it on the quiet side, it best to ride the bike path on weekdays. I did go on it one Sunday and it wasn't too bad but there was noticeably more traffic with bikers and walkers. Well, I hope you enjoyed my review of the Santa Ana River Trail from Green River to the Honda Center.

My husband and I rode this trail again today for the fourth time. It was cold and windy. 25 mile ride from Aliso and Wood canyon nature preserve to cooks corner and back. Not much bird activity along the creek yet. Too cold I think. The parks were all full of soccer and Little League baseball activity. The trail is still closed at the I-5 due to construction. Be sure to take your GPS so you can navigate the detour through Lake Forest.

My husband and I rode from Aliso Wood Canyon nature preserve to Cook’s corner and back today. 25 miles total. It was a cold and windy ride today but this is still one of my favorite trails. Because it was Saturday, and we hit the trail at 9 AM, we ran into a 5K run, lots of walkers, and other bike riders. It still felt like winter along the trail. Not much bird activity on the creek yet. The trail is still closed at I-5 due to construction. Be sure to take your GPS to maneuver the detour through Lake Forest.

So many street crossings, it was frustrating. Not worth the time.

I ride it quite often, by often I mean almost every sunday morning year round...
But I ride the north portion only and not all the way for a combination of reasons.
First reason is, because of the river and the freeway, the path is pretty much a wind tunnel, so you waste a lot of energy when you have crosswind or front wind just fighting the wind.
Second reason is the fact the only shades you have on most of the path are from the bridges you cross, otherwise prepare to be frying specially between June and August.
Third reason are the homeless, I never had problems with them, but probably because Sunday mornings are relatively busy so they stay put, some are not even there by the time, but I wonder if that's the same on different hours with less traffic.
So what do I do them? First I stay on Riverside and ride the Zoo Drive all the way to the Crystal Spring Dr. until I reach the Los Feliz Blvd. and that's where I join the path, yes you have to share the road with some cars trying to reach the I-5, but if you use the crossing paths on traffic light and pay attention it's all good.
From there I ride to the end of the Greentrail (Near the Dodger Stadium) and return... On my way back I always stop by the Spokes Cafe around Atwater Village area. It's a nice cafe/bike shop focused on cyclists, not the cheapest place to stop by, but the food is high quality and the environment and staff are really nice and is a great place to meet other cyclists (before the pandemic was even better to share experiences and talk about cycling and making friends).
People that drive to the path, can park by the Griffith Park or another suggestion I would give if you wanna add some miles to your ride (specially if you have a EV this tip is golden cause that's what I sometimes do when I have to charge my car), park at Burbank Town Center (so you can leave your car on one of the chargers or superchargers for tesla owners) and ride from there through the bike lanes on San Fernando Blvd. to Riverside Dr. bike lane and them join the Bike Path or do as I do going thru the Griffith Park on Zoo Dr.

Went here today and honestly it wasn't bad. Large cracks in the path were a bit of a pain but it's not a major issue.. I fell 3 times but I was going backwards and not paying attention so thats all on me.

Asked police and a few workers at transit station... still got on the wrong trail...cut through town to this trail... very very poorly marked... got outside Escondido and trail disappeared...detours through...poorly marked... smart to avoid trail

Left transit station...no markings in plaza..rode about 2 miles....trail marked stay out...private land... other side of the canal is closed... the trail has no markings...avoid it

I start at Citrus and ride to Claremont. Nice ride, only one detour where a portion is being rebuilt; have to detour up to Arrow but it takes you thru the Colleges campus to the village.
