The trip starts at my house getting on PET from Campus Ave. in Upland. The distance is 17.5 miles one way from where I start. The trail goes east and at about two miles into the trip there are two brief climbs and from there on it's pretty much level. At the Foothill Blvd. trailhead there is restroom access. It's important to mention that unlike the Santa Ana River Trail,, there are many intersections you have to cross. With some short and some long stretches. After about nine miles, starting from the under the 15 fwy you will be on a mile stretch that is very bumpy with the concrete slabs. Not very pleasant at all for road bikes. This section ends with a rest area in Rancho Cucamonga. I look at this portion as the first half of PET. It's now mile 10.

The second half of PET begins across Baseline Rd. where you enter Fontana. You are now going southeast. The trail takes on a different character where you are in a community setting and many portions of the trail have a neat accent to them. There's a park at Oleander Ave. with a nice restroom right off PET to your left. Other parks and exercise equipment are alongside the trail, along with a number of historical buildings. Once you enter the city of Rialto, you see neat signs telling you you're at Rialto with numerous cement benches and water fountains. The trail ends at Cactus Ave. at mile 17.5.

I gave this trail a four because in Fontana and Rialto I noticed that the trail isn't being kept up regarding weeds growing inbetween the concrete slabs you're riding on. Those weeds often have thorns that can puncture tires. I recommend you check the weather forecast for wind. Cucamonga, Fontana, and Rialto are know as "wind tunnels" so better to be safe than sorry. On my second trip, I did notice signs of the homeless with trash and other items associated with them. It wasn't much but I suspect it's going to get worse because on my first trip I didn't see anything. That's not good. Hope it doesn't get too bad!

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.

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.

Recommend to walk or ride bike on this trail. Relax and enjoy nature! :)

The trail is nice, but you have to stop at every street, and in most cases get off your bike as there are a lot of nuisance barricades and signs. It really detracts from the enjoyment of the trail, especially on the east end, where it's so frustrating that it's almost better to take the streets. I think this is a much nicer trail for walking than for cycling. The west end is a lot better, and I will probably ride it sometimes, west of santa fe springs.

Tried it for the first time, nice trail that follows the Santa Ana river. Nice and paved all the way, scenic of birds and mountains. Maybe three sections of homeless camps but nothing to worry about. I made it a little pass Rancho Jurupa Regional Park before I turned back to Colton starting point.

these trails are awesome and full if wild life and scenery..but also be aware that you share the trails with bike riders and equestrians..please be cautious in blind spots you might be surprised who you come face to face with ...most equestrians are open to having thier horses approached but please ask first ..and be cautious around them ..
