Nice trail with scenic views of ocean and mountains. Nothing difficult. Should be rated green.

Some ruts and normal rocks for a blue mountain bike trail. Good flow. By no means are there any rock gardens. Rate it a solid blue due to decent speed, elevation loss and switch backs. Nothing to be scared of.

I rode this from the Encinal trailhead up to the fire road and back. My 3 year was riding shotgun and this was honestly a great trail, especially for beginners or those taking their kids. It's got a mellow climb and enjoyable descent with beautiful views.

Just realize this is a very popular trail and ride in control and/or bring bells. I rode on a Sunday morning and had at least 3 guys rip around blind corners nearly crashing into us.

3.8 miles of fun flow, maybe 30 total yards of semi tech. Not really worth going above single track unless you want more views or are on a bigger ride. Doable and fun on pretty much anything from gravel to enduro. Bring a bell, trail has lots of fun/blind corners, but be careful recent drainage work has really ruined the exits on a few.

Trail should be green, not blue. Rode it both ways and nothing technical or difficult, climbs or going down. Views are nice but trail not super interesting.

This trail is a nice workout trail with great views. But the downhill sections are more green than blue; nothing too technical. Climbs are blue for sure. Did it both ways, have a slight preference for Encinal-Kanan direction.

Don’t know what to think about this trail. I completed it both way so I can have an educated guess. Scenery are beautiful. But the climbing parts are pretty grueling (both ways) and technical. You either need very strong legs or an ebike. I had neither! The downhill sections are pretty nice and chunky. Round trip is 2,500 ft elevation.

Trail is pretty fun, technical and long. Loved riding it down. The only drawback of this trail is to come back where you started. If you don’t shuttle, you’ll suffer!

This trail should be a bike trail. Complete BS that it is not. Who actually makes these stupid arse rules?

Visiting the area and had a fun evening riding here. I took the fire road from the campground on the coast side up to Backbone and rode that down. The switchback fire road seemed to have most of the steep climbing in the first half. I am 52, 6’4” and 260 lbs and I made it up. Some great views to the ocean and also inland along the climb. Backbone is a flow trail some of the time and some set chunky rock other times. It is not extremely technical. I rode up a ways on the main dirt road, Sycamore and took a quick ride down the green trail that runs along that road. That was a really fun and fast trail.

A bit bumpy in the middle and then chunky at the end. Nothing an enduro bike can't handle, but do keep in mind if you are expecting the smooth entrance to be indicative of the entire thing, you will be mistaken ;-)

Just a suggestion to folks that the canyon is pretty crowded during the Fall on weekends and there are lots of ways to get up to the top other than riding or pushing up Backbone. The trail is narrow enough in places that it is not possible to keep a safe distance as uphill and downhill traffic pass. We had to climb off the trail for 3 different groups this weekend to let them pass upwards as we were descending. Push up or ride Hell Hill or the switchback fire road.

Rode the section between Kanan Dume and Latigo. Trail is very overgrown and needs some love. What a beautiful piece of single track.

descent on way back is super fun. Single track at start and at end. Steeper climbs at top are fire road/double track.
