Trail is in great shape considering the traffic and recent rains. Not sure why anyone would complain. If an old keg of fat can climb the whole trail to cocktail without putting a foot down… the trail is running really well.

There is no YouTube video that will show you current conditions, this is now a full black trail and should be updated. Uphill is a complete disaster as you will pedal strike inside most ruts. Since the trail is narrow you have no choice but to get inside the rut but you should be fine with not pedal striking the edges. The corners lost significant amount of dirt and it just exposed rock after the rains and even experienced bikers will walk them. Too bad, this used to be so flowy.

This is not really a trail. This is a section of "North Main Divide" 3S04 forest service road.

This trail is the only trail in OC that feels like your a 100 miles from anywhere else. There are ticks in the fall and hot in the summer. So little used the trail closes in during high rainfall years. It’s an adventure ride with lots if climb and not technical. Gets right down to business with lots of climbing at first then mellows out a bit. Bring lots of water

I would not recommend this trail to anyone. As you can see from my pictures we had to be air lifted out. This trail is a lot of up hill and exhausting. It is not fun, and the maps are misleading. Fatalities have occurred out here due to dehydration and exhaustion. We are lucky to be alive. There was not a single soul biking that day and I doubt anyone does this trail either. This is meant for trucks and dirt bikes. Take my word and please be safe by not coming here.

In all respect... you got air-lifted off Main Divide? It's a FIRE ROAD! I have ridden this section of trail more times than I can count. It is a 50 minute ride at a moderate (not fast) pace. It is mostly downhill (albeit with some short, steep climbs), and you lose 800 feet of elevation over the 6 mile length. Is your trail comment intended to be a joke(?)

One of the steepest parts of Main Divide. Attempted to ride up this today but was a bit too steep & rocky for my 26er.
