A nice XC ride with great views. Unfortunately, the sections of the trail that allow Motos are destroyed in places. Large ruts and dips in the trail in unpredictable places make the trail unreliable for the rider.

We rode south to north, parking at the northern end and riding the road first. I'd recommend this direction because you get to climb on nice switchbacks that haven't been destroyed by Motos and then descend on the more rough stuff at the northern end. Nothing very technical on this trail but look out for unexpected trail erosion.

I rode this up from Stone Creek on July 5, it's a hardy climb especially if you arrived the day before form sea level! The initial switchbacks take a toll but once you pass those the climb mellows out and those views appear. I did this as an out and back, it's not a bad descending trail, but you could also continue on north on the central Bangtail section and then descend to the highway on Olsen Creek Rd and return to the Stone Creek trailhead. Also can be done as North to South from the top of Olsen Creek Rd, climbing the central section and then descending the south section to Stone Creek. Nothing particularly rugged, I was flying down the open straightaways.

I rode this today from Olsen Creek, so north to south. I drove up Olsen Creek Rd and parked, then took the 5+ mile ride to the large meadow before the descent to south Bangtail. Solid fun, about 1300 ft of climbing on the outbound and then fun return. I’d actually call most of this section XC and saw a guy on a gravel bike. Super fun that it has some stellar views but also is in some thicker woods for parts of the ride too. Shared with Motos but only a few places where they have cratered it out, otherwise is a nice smooth track w just a few rocky areas.

Beautiful views! If you want to see the wildflowers now is a great time to go. Trees were down over the trail in 6 spots. Three small areas where we had to lift and trek the bikes over snow drifts. Otherwise perfect weather to ride.

Good, clean fun. Rode on moto, but would be a great pedal too. Flowy, smooth, no face wackers.

Motorized access is destroying this trail. Sad to see a epic trail slowly erode into a rutted v rather than smooth flowing singletrack
