Did the section between Bundy Gateway and Upper Bundy Canyon, and it was pretty good! Overgrown in some places (I’d wear long pants next time), but you can ride that section from end to end. There is exposure in some places, but the trail surface is smooth and it’s a pretty easy ride.

Unfortunately it’s too overgrown to ride right now.

Don’t ride… abandon trail… overgrown vegetation with poison oak. Trail is not maintained.

I’m actually glad most people don’t like this trail. It’s not for people who don’t like real tight exposure with super loose conditions, challenging climbs, or steep and loose and off camber switchbacks that are also exposed. You should probably avoid. You probably won’t like it.

Not in love with that trail. Seems abandoned. Lot of switchbacks.

Bundy Canyon, aka Riordan Trail, is a spectacular trail that can be accessed from St Mary’s, Mountain Gate, Tigertail, or Kenter. Most riders will hike at least a few, short sections. 100% single track. Extremely varied with cliff hugging, scary exposed sections, a shady creek bottom with ancient Walnut trees, tight switchbacks, and beautiful wildflowers in spring. Strong climbers will love it; others may find it an unrelenting sufferfest. Recent trail improvements have substantially improved the love to suffer ratio. Now worth riding as an out and back; equally fun, and difficult, in both directions.

Just wanted to add that there really should be a way for riders and hikers to circumnavigate the gated community at the top to get back to Canyonback Rd. After casing it out on google earth, it looks like you have to either clamber over the fence...or, go back the way you came. We lucked out and had some neighbors call security to let us through. They were very nice but it's not advised to bother them unless it's an emergency.

This trail is polarizing. It has moments of awesomeness and moments that suck. If you're looking to get in a good work out and don't mind a little hike a bike in spots, it's dfnly worth it. In certain sections, the exposure and the narrow trail reminds me of something you'd expect to ride in the San Gabriels. Thank you to those of you who put in the leg work to get this trail back on the menu.

Not sure what the previous reviewer rode, but LBC is not abandoned or overgrown at all. No poison oak unless you go off trail. I ride it once a week at least. It’s actually in good shape and fun to ride. Exciting exposure, tough climbs and switchbacks, cool scenery. Combine with Tree Fern for a nice loop, but walk the 100’ cliff section.

It was my first time on this trail, initially confused as this trail is still raw and not packed but is easy ridable with a mountain bike. Trail leads down to a pretty loose and narrow descent (fear of flying).
