I have a bad foot and riding a bike has zero impact on it so I can go and go when trails are flat. I catch it right at the I-15 and Baseline. I'm happy.

Upper trail is about 18 miles one way. Trail condition are good, path is well maintained. Not the most scenic, but there were zero traffic intersections to negotiate. Most of upper riverbed was dry.

Pretty awesome bike trail From mountain to seal beach, there is plenty points can let you out and park your car there. More than maps shows. But in the middle, 18m ~ 13 there are some horse manures on the ground which stinks and make the road ugly and it seems nobody will clean them up. I spent about 7-10 trips to finish the whole. 6 miles round trip per trip since I do have friends to complete with

This trail is great. The first three miles are gorgeous, surrounded by orange trees, the mountains, and the equestrian center. The smell is not the most pleasant for the first half mile, but still bearable. The last three miles are okay - the San Juan Creek is not pretty by any means, but it is neat to follow the downtown San Juan Capistrano area for a little bit. I wish the signage was better when crossing La Novia Street. Signage was also a tad confusing and I actually merged into the Trabuco Creek Trail before realizing and turning around and crossing the bridge. .

Counted 28 traffic light crossings and another 24 crossings with stop signs. However, very functional community bike transportation corridor. Paving good, but yes, it lacks restrooms.

I’ll make this short and too the point. 1. Needs a restroom facility on the trail at least halfway throughout the trail. 2. Lots of bumps in between intersections. 3. Lots of sketchy people chilling on the trail around Euclid through Upland towards Claremont .

these trails are actually really fun but yet very distant. i find it enjoyable to bike through these trails catching a breeze & watch bunnies or lizards come across the road every now & then. these trails can also lead to the norco powerhouse which is awesome to take pictures in & is close to the river. however, it feels a bit uncomfortable going though a plant nursery & interrupting people’s jobs. also, it does smell like horse dropping throughout the way so hopefully you don’t mind.

Nice trail to ride without cars. Go early because you will heat up. Free of debris. I am happy that I changed from my usual ride. Many parks along the way.

I guess I am the only one reviewing this trail who actually both runs and rides every inch of this trail on a regular basis. My home is near Milliken and is just several block north of the trail. I typically run from my home to the trail at the central park, and decide either westbound (to Claremont Blvd or even a little bit further to the metrolink station) for about 20 miles out & back, or eastbound (to Fontana, and recently as trail expanded, into Rialto) for 20 to 22 miles. Except for two parks near the trail in Rancho, there is no restroom. But water fountain is abundant in west half of the Rancho west to east part of Upland, then there is none in Claremont. There is again no water fountains in east part of the Rancho until you are 1 miles into Fontana, then you will enjoy at least one for each mile all the way into Rialto. Standing at the end of the trail, sometimes I can see the railway train on the rail shadowed by the far away snow capped mountains. If the trail continous eastbound, it will makes a sudden turn southbound before 215 freeway, and it will join the Santa Ana river trail, which eventually (except for miles of disconnect before Yorba Linda) goes all the way south to Huntington Beach. I heard that westbound of the trail also has the potential to join the San Gabriel river trail, though I have no ideal how it will go that way. Given the slow progress, not sure in my lifetime I can see that happens.
